f Task 4: Map the default MVC request routes

1. Import the System.Web.Mvc and System.Web.Routing namespaces in Global.asax to support MVC

request routing.

[Visual C#]using System.Web.Mvc;

using System.Web.Routing;

[Visual Basic]

Imports System.Web.MvcImports System.Web.Routing

2. Create a method named RegisterRoutes to register the MVC routes and exclude routes for existing

Web Form pages, handlers, and WCF services.

[Visual C#]

public static void RegisterRoutes(RouteCollection routes)

{routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");

routes.IgnoreRoute("{resource}.svc/{*pathInfo}");

routes.MapRoute(

"Default", // Route name

"{controller}/{action}/{id}", // URL with parametersnew { controller = "Home", action = "Index", id = "" } // Parameter defaults

);

}

[Visual Basic]Shared Sub RegisterRoutes(ByVal routes As RouteCollection)

routes.IgnoreRoute("{resource}.axd/{*pathInfo}")

routes.IgnoreRoute("{resource}.aspx/{*pathInfo}")routes.IgnoreRoute("{resource}.svc/{*pathInfo}")

routes.MapRoute(

"Default","{controller}/{action}/{id}",

New With {.controller = "Home", .action = "Index", .id = ""}

)End Sub

3. Call the RegisterRoutes in the Application_Start method.

[Visual C#]

protected void Application_Start(object sender, EventArgs e){




RegisterRoutes(RouteTable.Routes);

}

[Visual Basic]Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)

RegisterRoutes(RouteTable.Routes)

End Sub

4. Save the Global.asax file.

f Task 5: Change project to reflect an MVC Project

1. Open the project, AdventureWorks.csproj or AdventureWorks.vbproj file in Notepad for direct

editing.

2. Locate the ProjectTypeGuids element.

[Visual C#]

2 Lab Instructions: Developing MVC Views

Lab 5: Developing MVC Views

Note: You can perform the tasks in this lab by using either Microsoft Visual C#® or Microsoft Visual

Basic® as your programming language.

Objectives

After completing this lab, you will be able to:

• Create a List MVC view.

• Create a Details MVC view.

• Create a Create MVC view.

• Create an Edit MVC view.

• Create a Delete MVC view.

Introduction

In this lab, you create MVC views for listing, adding, editing, and deleting blog entries. You use strongly-

typed views, ViewData and TempData to retrieve the data from the controller. Also, you use partial views

to reuse markup that is used on multiple pages.




Lab Scenario

Based on your recommendations for redesigning the AdventureWorks website, the blog pages need to be

developed by using MVC. You have already created an ADO.NET Entity Data Model to build your MVC

model classes. You have also developed an MVC controller to handle database operations. With the

database access and application logic in place, you now need to create a set of MVC views to render the

UI based on controller actions.




Exercise 1: Develop a List MVC ViewThe main tasks for this exercise are as follows:

1. Add a Blog menu item to the Site.Master page.

2. Add a view to display the complete list of blogs.

3. Test the new view.

Task 1: Open the AdventureWorksMvc solution in Visual Studio 2010







Task 2: Add a Blog menu item to the Site.Master page

1. Open the Site.Master page.

2. Add a menu item to the menu on the Site.Master master page, by using an Html.ActionLink method wrapped in a li HTML element, within the ul element, with an id attribute value of menu.

Add the new menu item between the Home and About menu items.

[Visual C#]

<li><%= Html.ActionLink("Blog", "", "Blog")%></li>

[Visual Basic]

<li><%: Html.ActionLink("Blog", "", "Blog")%></li>

3. Verify that the ul element matches the following markup.

[Visual C#]

<ul id="menu">

<li><%= Html.ActionLink("Home", "Index", "Home")%></li><li><%= Html.ActionLink("Blog", "", "Blog")%></li>

<li><%= Html.ActionLink("About", "About", "Home")%></li>

/ul>

[Visual Basic]

<ul id="menu">

<li><%: Html.ActionLink("Home", "Index", "Home")%></li><li><%: Html.ActionLink("Blog", "", "Blog")%></li><li><%: Html.ActionLink("About", "About", "Home")%></li>

</ul>

Task 3: Add a view to display the complete list of blogs

1. Add a Blog subfolder to the Views folder.

2. Add an empty view named Index.aspx, based on the Site.Master page, to the Blog folder.

3. Update the new view to a strongly-typed view of type

System.Web.Mvc.ViewPage<IEnumerable<AdventureWorksMvc.Models.Blog>> or

System.Web.Mvc.ViewPage(Of IEnumerable (Of AdventureWorksMvc.Blog)).




4. Add the following markup and code to the Index view in the Content2 Content control, immediately

after the h2 element.

[Visual C#]

<% foreach (var item in Model)

{ %><div>

<%: Html.ActionLink("Details", "Details", new { id=item.BlogID })%><%: item.DatePosted %>-

<%: item.Title %>

</div>

<% } %>

[Visual Basic]

<% For Each item As AdventureWorksMvc.Blog In Model%>

<div>

<%: Html.ActionLink("Details", "Details", New With {.id = item.BlogID})%><%: item.DatePosted %>

-<%: item.Title %>

</div>

<% Next%>

5. Verify that the markup and code in the Index view matches the following.

[Visual C#]

6. Modify the Page_Load method in the Products class as shown.

[Visual C#]

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack){

string categoryName = null;

string categoryId;

// Retrieve category param from "/Products/{Category}" URL

categoryId = Page.RouteData.Values["category"].ToString();

categoryName =

DataAccessLayer.Products.GetCategoryName(int.Parse(categoryId));lblCategory.Text = categoryName;

var data =DataAccessLayer.Products.GetProductsByCategory(int.Parse(categoryId));

gvProducts.DataSource = data;gvProducts.DataBind();

}}

[Visual Basic]

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

If Not Page.IsPostBack ThenDim categoryName As String = Nothing

Dim categoryId As String

' Retrieve category param from "/Products/{Category}" URL

Exercise 1: Modifying a Web Forms Page to Display Localized ContentThe main tasks for this exercise are as follows:

• Create resource files so that Default.aspx can display the page in English and• language of your choice.• Localize the Site.Master master.




• On the Start menu of 10264A-GEN-DEV, point to All Programs, click Microsoft Visual Studio2010, and then click Microsoft Visual Studio 2010.

3. Open the AdventureWorks solution from the following location.




f Task 2: Create resource files for Default.aspx

1. Analyze the markup in Default.aspx.

2. Generate local resources for Default.aspx, by using the Generate Local Resource functionalityavailable in Design view.

Note: This automatically creates the App_LocalResources folder in the root of your webapplication, if one does not already exist. The process also creates a resource file calledDefault.aspx.resx, in the App_LocalResources folder.

3. Switch back to Source view of Default.aspx.

4. Notice that both the lbCategories and btnCategory server controls have had an extra attributecalled meta:resourcekey added to the existing markup.

<asp:Button ... meta:resourcekey="btnCategoryResource1"></asp:Button><asp:ListBox ... meta:resourcekey="lbCategoriesResource1"></asp:ListBox>

Note: The values of these attributes are used to find the localized values for the properties of thelocalizable controls in the Default.aspx.resx file.

5. Notice that the Page directive at the top of the page now contains the following information.

<%@ Page ... culture="auto" meta:resourcekey="PageResource1" uiculture="auto" %>

6. Open Default.aspx.resx.

Note: In the Resource Editor, you will see a list with all the localizable properties of the localizablecontrols from the Default.aspx page.

7. Switch back to Default.aspx.




8. Notice that the text strings Welcome to AdventureWorks! and Product Categories were notmodified, and they were not added to the .resx file either. This is because they were hard-coded inthe Web Forms page.

9. Localize the hard-coded Welcome to AdventureWorks! text implicitly, by adding a Localize servercontrol within the h2 element, with the following attributes.

Attribute Value

ID lclWelcome

Text Welcome to AdventureWorks!

meta:resourcekey LocalizeResource1

10. Delete the text Welcome to AdventureWorks! from the h2 element.

Note: Make sure that you do not delete the text Welcome to AdventureWorks! from theLocalize server control.

11. Add a resource string named lclWelcomeResource1.Text to the Default.aspx.resx resource file. Thestring must have the value of Welcome to AdventureWorks!.

12. Localize the hard-coded Product Categories text explicitly, by adding a Literal server control withinthe p element, with the following attributes.

Attribute Value

ID ProductCategoriesLiteral

Text <%$ Resources: ProductCategoriesLiteral.Text %>

13. Delete the text Product Categories from the p element.

Note: Make sure that you do not delete the text Product Categories from the Literal server

control.

14. Add a resource string named ProductCategoriesLiteral.Text to the Default.aspx.resx resource file.The string must have the value of Product Categories.


16. Verify that Default.aspx Web Form looks the same as it did before you modified it.


18. Add an existing German resource file for the Default.aspx Web Form to the App_LocalResources folder. The file is named Default.aspx.de.resx and it is located in the D:\Lab Files\CS\Lab07\Starter\Exercise 01 or D:\Lab Files\VB\Lab 07\Starter\Exercise 01 folder.

f Task 3: Localize the Site.Master master page


2. Localize the hard-coded Log In text, by adding a Literal server control within the a element, with thefollowing attributes.




Attribute Value

ID LoginLiteral

Text Log In

3. Delete the text Log In from the a element.

Note: Make sure that you do not delete the text Log In from the Literal server control.

4. Localize the hard-coded Welcome text, by adding a Literal server control within theLoggedInTemplate element, with the following attributes.

Attribute Value

ID WelcomeLiteral

Text Welcome

5.

Delete the text Welcome from the LoggedInTemplate element.

Note: Make sure that you do not delete the text Welcome from the Literal server control.

6. Open the Site.Master master page in Design view.

7. Generate local resources for Site.Master, by using the Generate Local Resource functionality.

Note: This generates a new file called Site.Master.resx in the App_LocalResources folder.

8. Add an existing German resource file for the Site.Master master page to the App_LocalResources

folder. The file is named Site.Master.de.resx and it is located in the D:\Lab Files\CS\Lab07\Starter\Exercise 01 or D:\Lab Files\VB\Lab 07\Starter\Exercise 01 folder.

f Task 4: Test the web application


2. Show the AdventureWorks home page in German, by changing the language preference in theInternet Options dialog box.




Note: The page should now be shown in German.



Results: After this exercise, you should have a web application that supports different languages, andshows the site in the user’s preferred language.




Exercise 2: Persisting Data on Web Forms PagesThe main tasks for this exercise are as follows:

1. Use a cookie collection to persist user information, setting scope and lifetime to save the last chosencategory.

2. Store system-wide information in the Application object, to hold the number of simultaneous visitors

on the site.

3. Use the session object to store the shopping cart.

4. Configure session state to run in SQL Server.




ProgrammingLanguage Location



f Task 2: Use a cookie collection to persist user information and set scope and lifetime to

save the last chosen category


2. On postback, create a cookie object called Preferences that holds the current product category,saved as a value named LastCategory. Make sure that the cookie will expire after one minute. Thecookie must be appended to the response.

[Visual C#]

else{

if (lbCategories.SelectedIndex != -1)

{

string category = lbCategories.SelectedValue;

HttpCookie cookie = new HttpCookie("Preferences");cookie["LastCategory"] = category;cookie.Expires = DateTime.Now.AddMinutes(1);Response.AppendCookie(cookie);

Response.Redirect("/Products.aspx?id=" + category);

}

}

[Visual Basic]

Else

If lbCategories.SelectedIndex <> -1 Then

Dim category = lbCategories.SelectedValue

Dim cookie As New HttpCookie("Preferences")cookie("LastCategory") = categorycookie.Expires = DateTime.Now.AddMinutes(1)Response.AppendCookie(cookie)




Response.Redirect("/Products.aspx?id=" & category, True)

End IfEnd If

3. If the page is rendered for the first time, add code to check that a cookie named Preferences exists inthe request cookie collection, and if there is, read the LastCategory value from the cookie, and assignit to the SelectedValue property of the ListBox control.

[Visual C#]

if (!Page.IsPostBack){

List<ProductCategory> data = DataAccessLayer.Products.GetCategories();

lbCategories.DataSource = data;

lbCategories.DataBind();

HttpCookie cookie = Request.Cookies["Preferences"];if (cookie != null){

lbCategories.SelectedValue = cookie["LastCategory"];}

}

[Visual Basic]If Not Page.IsPostBack Then

Dim data As List(Of ProductCategory) =

AdventureWorks.DataAccessLayer.Products.GetCategorieslbCategories.DataSource = data

lbCategories.DataBind()

Dim cookie As HttpCookie = Request.Cookies("Preferences")

If Not cookie Is Nothing ThenlbCategories.SelectedValue = cookie("LastCategory")

End If


f Task 3: Store system-wide information in the Application object

1. Open Global.asax in Code view.

2. In the Application_Start method, overwrite the existing code, by adding a new application variablenamed OnlineVisitors, to the Application object. The variable must have a starting value of 0.

[Visual C#]

void Application_Start(object sender, EventArgs e)

{Application["OnlineVisitors"] = 0;

}


Application("OnlineVisitors") = 0End Sub

3. In the Session_Start method increment the value of the OnlineVisitors application variable by 1.Make sure you prevent multiple threads from writing to the application variable, by locking theApplication object before writing, and unlocking once you have finished writing to it.

[Visual C#]




void Session_Start(object sender, EventArgs e)

{Application.Lock();int visitors = (int)Application["OnlineVisitors"];visitors++;Application["OnlineVisitors"] = visitors;Application.UnLock();

}

[Visual Basic]

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)Application.Lock()Dim visitors As Integer = Integer.Parse(Application("OnlineVisitors"))visitors += 1Application("OnlineVisitors") = visitorsApplication.UnLock()

End Sub

4. In the Session_End decrement the value of the OnlineVisitors application variable by 1, if thecurrent value is not 0. Make sure you prevent multiple threads from writing to the applicationvariable, by locking the Application object before writing, and unlocking once you have finishedwriting to it.

[Visual C#]

void Session_End(object sender, EventArgs e)

{

Application.Lock();int visitors = (int)Application["OnlineVisitors"];if (visitors > 0){

visitors++;Application["OnlineVisitors"] = visitors;

}

Application.UnLock();}

[Visual Basic]

Sub Session_End(ByVal sender As Object, ByVal e As EventArgs)

Application.Lock()Dim visitors As Integer = Integer.Parse(Application("OnlineVisitors"))

If visitors > 0 Thenvisitors -= 1Application("OnlineVisitors") = visitors

End If

Application.UnLock()End Sub


f Task 4: Use the session object to store the shopping cart

1. Open the ProductDetails Web Form in Code view.

2. Upon postback, the Order button has been pressed, so the information entered in the Web Form ispersisted. In the Page_Load method, notice how the product ID, product name, and list price, whichare not displayed to the user, are saved to hidden fields. In the btnOrder_Click event handler, noticethat a new List object of type clsShoppingCart is created and saved to Session state. Finally, the useris redirected to the ShoppingCart Web Form.




3. Open the ShoppingCart Web Form in Code view.

4. Analyze the code in the Page_Load method.

f Task 5: Configure session state to run in SQL Server

1. Open the Web.config file.

2. Configure your application to use the local SQL Server® instance named SQLExpress, for persistingsession information instead of the default InProc mode.

<system.web>...

<sessionState mode="SQLServer" sqlConnectionString="Integrated Security=SSPI;DataSource=.\SQLExpress;" /></system.web>

3. Configure the local SQL Server instance SQLExpress to host the state database, by running thefollowing command from the Visual Studio Command Prompt (2010). The Visual Studio CommandPrompt (2010) must be run as an administrator.

aspnet_regsql -E -S .\SQLExpress -ssadd

4. Open the SQL Server Command Line Tool, by running the following command from the Visual

Studio Command Prompt (2010).

sqlcmd –E –S .\SQLExpress

5. Add permissions for the user Student to access the tempdb and ASPState database to use the newSQL Server Session state, by running commands from the SQL Server Command Line Tool withinthe Visual Studio Command Prompt (2010). The commands are saved in the D:\Lab Files\CS\Lab07\Starter\Exercise 02\ASPState.txt or D:\Lab Files\VB\Lab 07\Starter\Exercise 02\ASPState.txt file, from where you can copy them and paste them into the SQL Server Command Line Tool.

6. Close the SQL Server Command Line Tool, by running the following command from the VisualStudio Command Prompt (2010).

quit

7. Close the Visual Studio Command Prompt (2010).8. Close Visual Studio 2010.

Results: After this exercise, you should have implemented state using different techniques, includingApplication and Session state.




Exercise 3: Utilizing View State EffectivelyThe main tasks for this exercise are as follows:

1. Configure the view state to persist page data.

2. Disable the view state and its effects.

f Task 1: Open the AdventureWorks solution in Visual Studio 20101. Open Microsoft Visual Studio 2010.





f Task 2: Configure view state to persist page data


2. View the source of the Default.aspx page in Internet Explorer, by using the View Source functionality.

3. Analyze the HTML code, and pay special attention to the __VIEWSTATE field.

4. Close the View Source window.


6. Open the Default.aspx Web Form.

7. Disable view state for the lbCategories server control.

<asp:ListBox ID="lbCategories" runat="server" DataTextField="Name"DataValueField="ProductCategoryID"

Height="270px" Width="186px" EnableViewState="False"

></asp:ListBox>



10. Analyze the HTML code, and pay special attention to the __VIEWSTATE field, which is now muchsmaller, almost half the size.


12. Notice the effects of disabling view state for the lbCategories server control, by clicking Submit.

Note: The lbCategories server control is now empty because it is not being populated by theserver code on a postback.


f Task 3: Disable view state and its effects

1. Disable view state for the Default Web Form by setting the EnableViewState property to False.

<%@ Page Title="Home Page" ... EnableViewState="False" %>





3. Click Submit.

Note: The lbCategories server control is now empty because it is not being populated by theserver code on a postback.


5. Enable view state for the lbCategories server control.


Height="270px" Width="186px" EnableViewState="True"

></asp:ListBox>


7. Click Submit.

Note: The lbCategories server control is now empty, even if you enabled view state for the control.This is because disabling view state for a control or page will disable the view state for all childcontrols.


9. Remove the EnableViewState attribute and value from the Page directive.

10. Remove the EnableViewState attribute and value from the lbCategories server control.

11. Disable view state for the Default Web Form by setting the ViewStateMode property to Disabled.

<%@ Page Title="Home Page" ... ViewStateMode="Disabled" %>

12. Enable view state for the lbCategories server control by setting the ViewStateMode property to

Enabled.


Height="270px" Width="186px" ViewStateMode="Enabled"></asp:ListBox>


Note: The rendered page looks okay.

14. Click Submit.

Note: The lbCategories server control is still populated because view state has been enabled forthe server control.






Results: After this exercise, you should have examined and implemented the view state in different

ways.

4 Lab Instructions: Developing Client-side Scripts and Services

Exercise 1: Using jQueryThe main tasks for this lab are as follows:

• Register a jQuery library in the HTML header.

• Use selectors and events.

• Use the tableSorter jQuery library to allow client-side sorting.





f Task 2: Register a jQuery library in the HTML header


2. Ensure that the jquery-1.4.1.js and jquery.tablesorter.min.js file are located in the Scripts folder.

3. In the head element of the Site.Master file, add the following script elements.

<head runat="server">

<title></title><link href="~/Styles/Site.css" rel="stylesheet" type="text/css" />

<script src='<%= ResolveUrl("~/Scripts/jquery-1.4.1.js") %>'type="text/javascript"></script>

<script src='<%= ResolveUrl("~/Scripts/jquery.tablesorter.min.js") %>'type="text/javascript"></script>

<asp:ContentPlaceHolder ID="HeadContent" runat="server"></asp:ContentPlaceHolder>

</head>

Note: Make sure that you add the closing script tag (</script>) and not the self-closing script tag

(</>). The self-closing tag for the script references is not recognized by the browsers.

Best Practices: For Web Forms applications, you can use the ResolveUrl method, which correctly

resolves the URL relative to the request.

f Task 3: Use selectors and events


2. Select the Bike Stands product category and click Submit.

3. Select the All-Purpose Bike Stand product.

4. Add the product to the shopping cart.

5. View the source for the rendered page.

6. Locate the gvCart GridView control, and note the ID for the rendered server control.

<table cellspacing="0" rules="all" border="1" id="MainContent_gvCart" style="border-

collapse:collapse;">

7. Close the source window.





9. In the Site.Master master page, insert the following JavaScript element, after the closing html tag.

<script type="text/javascript">

$(document).ready(function () {$("#MainContent_gvCart").tablesorter();

});

</script>

f Task 4: Use the tableSorter jQuery library to allow client-side sorting

1. Open the ShoppingCart.aspx Web Form in Code view.

2. Update the Page_Load method to reflect the following code. (This ensures that the thead and tbody

HTML elements are rendered with the GridView control.)



{

if (Session["_cart"] != null){

List<clsShoppingCart> cart = (List<clsShoppingCart>) Session["_cart"];gvCart.DataSource = cart;gvCart.DataBind();

}

else{

lblMessage.Text = "Your cart is empty";

btnPlaceOrder.Visible = false;

}}

if (this.gvCart.Rows.Count > 0){

gvCart.UseAccessibleHeader = true;gvCart.HeaderRow.TableSection = TableRowSection.TableHeader;

gvCart.FooterRow.TableSection = TableRowSection.TableFooter;}

}

[Visual Basic]Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles

Me.Load

If Not Session("_cart") Is Nothing Then

Dim cart = CType(Session("_cart"), List(Of clsShoppingCart))gvCart.DataSource = cart

gvCart.DataBind()

ElselblMessage.Text = "Your cart is empty"

btnPlaceOrder.Visible = False

End If

If gvCart.Rows.Count > 0 ThengvCart.UseAccessibleHeader = TruegvCart.HeaderRow.TableSection = TableRowSection.TableHeadergvCart.FooterRow.TableSection = TableRowSection.TableFooter

End IfEnd Sub


4. Select the Bike Stands product category, and then click Submit.







8. Select the Bib-Shorts product category, and then click Submit.

9. Select the Men's Bib-Shorts, L product.10. Add the product to the shopping cart.


12. Locate the gvCart GridView control, and note that the thead and tbody HTML elements are

rendered.



<thead><tr>

<th scope="col">ID</th><th scope="col">Name</th><th

scope="col">Price</th><th scope="col">Quantity</th>

</tr>

</thead><tbody><tr>

<td>879</td><td>All-Purpose Bike Stand</td><td>1</td><td>159</td>

</tr></tbody><tfoot>


14. Click the ID column header.

Note: Notice how the rows are sorted ascending according to the value of the ID column for the

individual rows.

15.

Close Windows Internet Explorer.16. Close Visual Studio 2010.

Result: At the end of this exercise, you should have enhanced the ShoppingCart interface to support

client-side sorting. You also learned how to perform script reference and use selectors in jQuery.




Exercise 2: Using Advanced jQueryThe main tasks for this exercise are as follows:

1. Implement jQuery events and effects.

2. Create a custom plug-in.

f Task 1: Open an existing ASP.NET web application1. Open Microsoft Visual Studio 2010.


f Task 2: Implement jQuery events and effects

1. Open the Products.aspx Web Form.

2. Locate the markup for the GridView control named gvProducts.

3. Append a custom TemplateField column to the Columns element of the gvProducts GridView

control.

<asp:BoundField DataField="ListPrice" HeaderText="List Price"DataFormatString="{0:c}" /><asp:TemplateField HeaderText="Ad">

<ItemTemplate><div style="display: none">

Advertisement for<%# Eval("Name") %>

</div></ItemTemplate>

</asp:TemplateField></Columns>

4. Append the following script element to the Products.aspx Web Form, at the end of the Content control with an ID attribute value of BodyContent.


$(document).ready(function () {$("a").mouseover(function () {

var divs = $(this).closest("tr").find("div").fadeIn("slow");

});

$("a").mouseout(function () {

var divs = $(this).closest("tr").find("div").fadeOut("slow");

});});

</script>

</asp:Content>


6. On the Products page, hover the mouse over the name of the product.

Note: The custom advertisement message is displayed in the rightmost column.


f Task 3: Create a custom plug-in

1. Add the following markup and code in the script element in the Products.aspx Web Form.





$(document).ready(function () {

$("a").mouseover(function () {var divs = $(this).closest("tr").find("div").fadeIn("slow");

});



});});

jQuery.fn.fadeInFadeOut = function (speed) {$(this).fadeIn(speed, function () {

$(this).fadeOut(speed);});

}


$(this).closest("tr").find("div").fadeInFadeOut("slow");});

});</script>



Note: The custom advertisement message is displayed in the rightmost column, but now it closes after

a short period.



Result: After this exercise, you should be able to embed jQuery effects in your application.




Exercise 3: Creating a WCF ServiceThe main tasks for this exercise are as follows:

1. Create an Ajax-enabled WCF service.

2. Add logic to the query, and return a random product from the database.

3. Examine the service configuration in the Web.config file.

4. Invoke WCF service using client-side code from the master page.




f Task 2: Create an Ajax-enabled WCF service

• Add a new Ajax-enabled WCF service named ProductsService to the project.

f Task 3: Add Logic to the query and return a random product from the database

1. Remove the default DoWork method and comments from the service class.

[Visual C#]// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat isWebMessageFormat.Json)

// To create an operation that returns XML,

// add [WebGet(ResponseFormat=WebMessageFormat.Xml)],// and include the following line in the operation body:

// WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";

[OperationContract]public void DoWork()

{

// Add your operation implementation herereturn;

}

// Add more operations here and mark them with [OperationContract]

[Visual Basic]' To use HTTP GET, add <WebGet()> attribute. (Default ResponseFormat is

WebMessageFormat.Json)' To create an operation that returns XML,

' add <WebGet(ResponseFormat:=WebMessageFormat.Xml)>,

' and include the following line in the operation body:' WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"

<OperationContract()>

Public Sub DoWork()

' Add your operation implementation hereEnd Sub

' Add more operations here and mark them with <OperationContract()>

2. Add the following GetRandomProduct method to the ProductsService.svc file.

[Visual C#]public class ProductsService

{[OperationContract]public string GetRandomProduct(){

var random = new Random();




using (var db = new AdventureWorksEntities()){

var randomNumber = random.Next(1, db.Products.Count() + 1);var randomProduct = (from p in db.Products

where p.ProductID == randomNumberselect new { p.Name, p.ListPrice, p.ProductNumber

}).FirstOrDefault();return new

System.Web.Script.Serialization.JavaScriptSerializer().Serialize(randomProduct);}

}}

[Visual Basic]Public Class ProductsService

<OperationContract()>Public Function GetRandomProduct() As String

Dim random = New Random()

Using db = New AdventureWorksEntities()Dim randomNumber = random.[Next](1, db.Products.Count() + 1)

Dim randomProduct = (From p In db.ProductsWhere p.ProductID = randomNumberSelect New With {p.Name, p.ListPrice,

p.ProductNumber}).FirstOrDefault()

Return NewSystem.Web.Script.Serialization.JavaScriptSerializer().Serialize(randomProduct)

End UsingEnd Function

End Class

Note: We are invoking the ProductsService from the client side. Hence, we want the returned format

to be XML or Json. For this reason, we are using the JavaScriptSerializer class to serialize the class into

a valid Json format.

f Task 4: Examine the service configuration in the Web.config file


2. Examine the configuration markup in the system.serviceModel element, which has been created by

the Ajax-enabled WCF service project item template.

<system.serviceModel><behaviors>

<endpointBehaviors>

<behavior name="AdventureWorks.ProductsServiceAspNetAjaxBehavior">

<enableWebScript /></behavior>

</endpointBehaviors>

</behaviors><serviceHostingEnvironment aspNetCompatibilityEnabled="true"

multipleSiteBindingsEnabled="true" />

<services>

<service name="AdventureWorks.ProductsService"><endpoint address=""

behaviorConfiguration="AdventureWorks.ProductsServiceAspNetAjaxBehavior"

binding="webHttpBinding" contract="AdventureWorks.ProductsService" /></service>

</services>

</system.serviceModel>




f Task 5: Invoke WCF service using client-side code from the master page


2. Add a reference to the ProductsService WCF by adding a ScriptManager control.

<asp:ScriptManager ID="ScriptManager1" runat="server">

<Services>

<asp:ServiceReference Path="~/ProductsService.svc" /></Services>

</asp:ScriptManager>

3. Add the following code to the Site.Master master page, after the closing html tag, at the end of the

script element.

getRandomProduct();

4 Lab Instructions: Implementing Advanced Ajax in a Web Application

Exercise 1: Using Microsoft Ajax in an MVC PageThe main tasks for this exercise are as follows:

1. Add the Ajax libraries to the pages.

2. Update the Index action method.

3. Create an Ajax Product Categories partial view.

4. Render the Partial view on the Index view.




3. Open the AdventureWorksMvc solution from the D:\Lab Files\CS\Lab 13\Starter\Exercise 01 or

D:\Lab Files\VB\Lab 13\Starter\Exercise 01 folder.

f Task 2: Add the Ajax libraries to the pages

1. Open the Site.Master file, located in the Views/Shared folder.

2. At the top of the Site.Master file, in the head element, add a reference to the Microsoft Ajax

libraries.

<script src="<%= Url.Content("~/Scripts/MicrosoftAjax.debug.js") %>"

type="text/javascript"></script><script src="<%= Url.Content("~/Scripts/MicrosoftMvcAjax.debug.js") %>"

type="text/javascript"></script>

f Task 3: Update the Index action method

1. Locate the Index action method in the Products controller.

2. Return the product categories from the Index action method by modifying the existing code.

[Visual C#]

public ActionResult Index(string CategoryID){

int id = int.Parse(CategoryID);var prodCategories = pr.GetCategories();

return View(prodCategories);}

[Visual Basic]

Public Function Index(ByVal CategoryID As String) As ActionResultDim id As Integer = CInt(CategoryID)

Dim prodCategories = pr.GetCategories()

Return View(prodCategories)End Function

f Task 4: Create an Ajax Product Categories partial view

1. Create a strongly typed, partial view named _AjaxProductCategories, based on the

IEnumerable<AdventureWorksMvc.Models.ProductCategory> or IEnumerable(Of AdventureWorksMvc.Models.ProductCategory) data class.




2. Insert the following markup and code in the _AjaxProductCategories.ascx file, after the Control directive.

[Visual C#]

<% using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "productCategories" }))

{ %><select size="4" id="CategoryID" name="CategoryID" style="height: 270px; width:

186px;">

<% foreach (var ProductCategory in Model)

{ %><option value="<%= ProductCategory.ProductCategoryID %>">

<%= Html.Encode(ProductCategory.Name)%>

</option><% } %>

</select>

<div id="productCategories">

</div><% } %>

[Visual Basic]

<% Using (Ajax.BeginForm(New AjaxOptions With {.UpdateTargetId = "productCategories"

}))%><select size="4" id="CategoryID" name="CategoryID" style="height: 270px; width:

186px;">

<% For Each ProductCategory In Model%><option value="<%= ProductCategory.ProductCategoryID %>">


</option>

<% Next%></select>

<div id="productCategories">

</div><% End Using%>




f Task 5: Render the Partial view on the Index view

1. Open the Index.aspx view in the Views/Products folder.

2. Delete the existing markup in the Content2 Content control.

3. Add the following markup to the Index view, at the top of the Content2 Content control.

[Visual C#]<h2>

Product Catalog</h2>

<label>

Choose a Category:</label><br />

<% Html.RenderPartial("_AjaxProductCategories", Model);%>

[Visual Basic]

<h2>

Product Catalog</h2><label>

Choose a category:</label>

<br />

<% Html.RenderPartial("_AjaxProductCategories", Model)%>



Products

6. Base the Index view on a different data class, by modifying the Inherits attribute value in the Page

directive.

[Visual C#]

Inherits="System.Web.Mvc.ViewPage<IEnumerable<AdventureWorksMvc.Models.ProductCategory>>"

[Visual Basic]

Inherits="System.Web.Mvc.ViewPage(Of IEnumerable (Of

AdventureWorksMvc.ProductCategory))"



Results: After this exercise, you should have added the product line to the index view using the

Microsoft Ajax Library.




Exercise 2: Using jQuery in an MVC ViewThe main tasks for this exercise are as follows:

1. Add the jQuery library to the pages.

2. Create a Featured Products action.

3. Load the Featured Products when a category is clicked.





f Task 2: Add the jQuery library to the pages



libraries.

<script src="<%= Url.Content("~/Scripts/jquery-1.4.1.min.js") %>"type="text/javascript"></script>

f Task 3: Create the Featured Products action

1. Open the ProductsController.cs or ProductsController.vb file in the Controllers folder.

2. Create an action for the Ajax method to call. The following code returns a view populated with

products.

[Visual C#]

public ViewResult FeaturedProducts(string CategoryId)

{int id = int.Parse(CategoryId);

var products = pr.GetProductsByCategory(id);

return View("_FeaturedProducts", products);

}

[Visual Basic]

Public Function FeaturedProducts(ByVal CategoryId As String) As ViewResult

Dim id As Integer = Integer.Parse(CategoryId)

Dim products = pr.GetProductsByCategory(id)

Return View("_FeaturedProducts", products)

End Function

f Task 4: Load the Featured Products when a category is clicked


2. The Ajax method needs a place to put the results from the called function. Add a div element at the

bottom of the page, before the closing Content tag.

<br />

<div id="featured-products"></div>

3. Create the Ajax method call. This function calls the controller action, and then returns the results into

the featured products div created earlier. Add the following markup to handle the click event for

the rendered select element, at the bottom of the page, before the closing Content tag.






$("#CategoryID").click(function () {var id = $(this).val();

$("#featured-products").load('<%= Url.Action("FeaturedProducts") %>', {

CategoryId: id });});

});

</script>


5. In Windows Internet Explorer, click Submit.

6. In Windows Internet Explorer, in the Choose a category list, click Bib-shorts.

Note: The products for the chosen category are displayed below the list.



Results: After this exercise, you should have added a "Featured Products" section to the Index.aspx

page. Using jQuery, the page should update the featured products based on the selection in the ProductCategories list.




Exercise 3: Handling EventsThe main tasks for this exercise are as follows:

1. Display a status message.

2. Alert the user when an error occurs.

3. Test the Index view.





f Task 2: Display a status message

1. Open the Index.aspx page in the Views/Products folder.

2. Before the featured-products div element, add a div to display the Ajax status messages.

<div class="log"></div>

3. After the featured-products div element, add a div to display the Ajax error messages.

<div class="error"></div>

4. In the $(document).ready jQuery function, add the following functions to display and hide the status

messages.


$("#CategoryID").click(function () {

var id = $(this).val();$("#featured-products").load('<%= Url.Action("FeaturedProducts") %>', {

CategoryId: id });

});$('.log').ajaxStart(function () {

$(this).text('Loading...');$('.error').text('');

});$('.log').ajaxComplete(function () {

$(this).text('');});

});

f Task 3: Alert the user when an error occurs

1. After the .ajaxComplete function, add the following function to display the alert.

$('.error').ajaxError(function () {$(this).text('There was an error! Please try again later...');

});

2. Ensure that the Index view page matches the following.

[Visual C#]


Inherits="System.Web.Mvc.ViewPage<IEnumerable<AdventureWorksMvc.Models.ProductCategory

>>" %>


Products</asp:Content>


<h2>





<label>Choose a category:</label>

<br />

<% Html.RenderPartial("_AjaxProductCategories", Model);%><br />

Header="Size" />

</sdk:DataGrid.Columns></sdk:DataGrid>

f Task 4: Call the services asynchronously

1. In the Designer, double-click the CategoriesDataGrid control.

Note: This creates an event handler named

CategoriesDataGrid_SelectionChanged in the MainPage.xaml.cs or

MainPage.xaml.vb code-behind file.

[Visual C#]

private void CategoriesDataGrid_SelectionChanged(object sender,

SelectionChangedEventArgs e) { } [Visual Basic] Private Sub CategoriesDataGrid_SelectionChanged(ByVal sender As




System.Object, ByVal e As

System.Windows.Controls.SelectionChangedEventArgs) HandlesCategoriesDataGrid.SelectionChanged

End Sub 2. In the MainPage class, create a protected variable for the ProductServiceSLClient object.

[Visual C#]

public partial class MainPage : UserControl {

protected AdventureWorks.ProductServiceSLClient productService

= new AdventureWorks.ProductServiceSLClient();

... [Visual Basic]

Public Partial Class MainPage Inherits UserControl

Protected productService As NewAdventureWorks.ProductServiceSLClient()

... 3. In the MainPage class constructor, wire up event handlers for the two Web service methods.

[Visual C#]

public MainPage() {

InitializeComponent(); productService.GetProductCategoriesCompleted += new

EventHandler<AdventureWorks.GetProductCategoriesCompletedEventArgs

>(productService_GetProductCategoriesCompleted);productService.GetProductsByCategoryCompleted += new

EventHandler<AdventureWorks.GetProductsByCategoryCompletedEventArg

s>(productService_GetProductsByCategoryCompleted);

} [Visual Basic]

Public Sub New() InitializeComponent()

AddHandler productService.GetProductCategoriesCompleted,

AddressOf productService_GetProductCategoriesCompleted

AddHandler productService.GetProductsByCategoryCompleted,AddressOf productService_GetProductsByCategoryCompleted

End Sub 4. Each event handler needs a method to execute once the asynchronous call completes.

[Visual C#]

void productService_GetProductsByCategoryCompleted(object sender,

AdventureWorks.GetProductsByCategoryCompletedEventArgs e) { } void productService_GetProductCategoriesCompleted(object sender,

AdventureWorks.GetProductCategoriesCompletedEventArgs e) {




} [Visual Basic]

Private Sub productService_GetProductCategoriesCompleted(ByValsender As Object, ByVal e As

AdventureWorks.GetProductCategoriesCompletedEventArgs) End Sub Private Sub productService_GetProductsByCategoryCompleted(ByVal

sender As Object, ByVal e AsAdventureWorks.GetProductsByCategoryCompletedEventArgs) End Sub

5. When the page loads, the CategoriesDataGrid control must be populated. In the class constructor,

add a call to the service method GetProductCategoriesAsync.

[Visual C#]

public MainPage() {



>(productService_GetProductCategoriesCompleted); productService.GetProductsByCategoryCompleted += new

EventHandler<AdventureWorks.GetProductsByCategoryCompletedEventArgs

>(productService_GetProductsByCategoryCompleted); productService.GetProductCategoriesAsync();

} [Visual Basic]

Public Sub New() InitializeComponent() AddHandler productService.GetProductCategoriesCompleted,

AddressOf productService_GetProductCategoriesCompleted AddHandler productService.GetProductsByCategoryCompleted,

AddressOf productService_GetProductsByCategoryCompleted productService.GetProductCategoriesAsync()

End Sub f Task 5: Bind the data returned from the services to the grids

1. The initial call to GetProductCategoriesAsync returns to

productService_GetProductCategoriesCompleted. In the

productService_GetProductCategoriesCompleted method, bind the results using the ItemsSource

property returned by the service to the grid.

[Visual C#]

void productService_GetProductCategoriesCompleted(object sender,

AdventureWorks.GetProductCategoriesCompletedEventArgs e){

CategoriesDataGrid.ItemsSource = e.Result;

}

[Visual Basic]

Sub productService_GetProductCategoriesCompleted(sender As Object,

e As AdventureWorks.GetProductCategoriesCompletedEventArgs)

CategoriesDataGrid.ItemsSource = e.ResultEnd Sub




2. In the CategoriesDataGrid_SelectionChanged event handler, get the selected category, and retrieve

the products by category.

[Visual C#]

private void CategoriesDataGrid_SelectionChanged(object sender,SelectionChangedEventArgs e)

{ AdventureWorks.ProductCategory category =

CategoriesDataGrid.SelectedItem as AdventureWorks.ProductCategory;

productService.GetProductsByCategoryAsync(category.ProductCategory

ID);}




[Visual Basic]

Private Sub CategoriesDataGrid_SelectionChanged(sender As Object,e As SelectionChangedEventArgs)

Dim category As AdventureWorks.ProductCategory =

TryCast(CategoriesDataGrid.SelectedItem,AdventureWorks.ProductCategory)

productService.GetProductsByCategoryAsync(category.ProductCategoryID)End Sub • The call to GetProductsByCategoryAsync returns to the

productService_GetProductsByCategoryCompleted method, where the results returned by the

service should be bound to the ItemsSource property of the grid.

[Visual C#]


AdventureWorks.GetProductsByCategoryCompletedEventArgs e){

ProductsDataGrid.ItemsSource = e.Result;

} [Visual Basic]

Sub productService_GetProductsByCategoryCompleted(sender As

Object, e As

AdventureWorks.GetProductsByCategoryCompletedEventArgs) ProductsDataGrid.ItemsSource = e.Result

End Sub • The final code should like this.

[Visual C#]


protected AdventureWorks.ProductServiceSLClient

productService = new AdventureWorks.ProductServiceSLClient(); public MainPage() {



>(productService_GetProductCategoriesCompleted); productService.GetProductsByCategoryCompleted += new

EventHandler<AdventureWorks.GetProductsByCategoryCompletedEventArg

s>(productService_GetProductsByCategoryCompleted); productService.GetProductCategoriesAsync();

} private void CategoriesDataGrid_SelectionChanged(object

sender, SelectionChangedEventArgs e) { AdventureWorks.ProductCategory category =

CategoriesDataGrid.SelectedItem as AdventureWorks.ProductCategory; productService.GetProductsByCategoryAsync(category.ProductCategory

ID); } void productService_GetProductsByCategoryCompleted(object

sender, AdventureWorks.GetProductsByCategoryCompletedEventArgs e) {





} void productService_GetProductCategoriesCompleted(object

sender, AdventureWorks.GetProductCategoriesCompletedEventArgs e) {

CategoriesDataGrid.ItemsSource = e.Result; }

} [Visual Basic]

Partial Public Class MainPage Inherits UserControl Protected productService As New

AdventureWorks.ProductServiceSLClient() Public Sub New()

InitializeComponent() AddHandler productService.GetProductCategoriesCompleted

, AddressOf productService_GetProductCategoriesCompleted AddHandler productService.GetProductsByCategoryCompleted

, AddressOf productService_GetProductsByCategoryCompleted productService.GetProductCategoriesAsync()

End Sub

Private Sub CategoriesDataGrid_SelectionChanged(ByVal sender

As System.Object, ByVal e As

System.Windows.Controls.SelectionChangedEventArgs) Dim category As AdventureWorks.ProductCategory =

TryCast(CategoriesDataGrid.SelectedItem,

AdventureWorks.ProductCategory) productService.GetProductsByCategoryAsync(category.ParentProductCa

tegoryID) End Sub Private Sub productService_GetProductCategoriesCompleted(ByVal

sender As Object, ByVal e As

AdventureWorks.GetProductCategoriesCompletedEventArgs) CategoriesDataGrid.ItemsSource = e.Result

End Sub Private Sub productService_GetProductsByCategoryCompleted(ByVal sender As

Object, ByVal e AsAdventureWorks.GetProductsByCategoryCompletedEventArgs)

ProductsDataGrid.ItemsSource = e.Result End Sub

End Class f Task 6: Bind the data returned from the services to the grids

1. Set AdventureWorksSLTestPage.aspx as the start page.


Note: It might take a while to load the data from the WCF service.

3. Select the Bib-Shorts category.

Note: Notice how the Products list is populated with all the products for the selected category.

f Task 2: Register a jQuery library in the HTML header



2. Ensure that the jquery-1.4.1.js and jquery.tablesorter.min.js file are located in the Scripts folder.

3. In Solution Explorer, expand Scripts.

4. Locate the jquery-1.4.1.js and jquery.tablesorter.min.js files.

5. In the head element of the Site.Master file, add the following script elements.

<head runat="server">

<title></title>

<link href="~/Styles/Site.css" rel="stylesheet" type="text/css" /><script src='<%= ResolveUrl("~/Scripts/jquery-1.4.1.js") %>'

type="text/javascript"></script><script src='<%= ResolveUrl("~/Scripts/jquery.tablesorter.min.js") %>'

type="text/javascript"></script><asp:ContentPlaceHolder ID="HeadContent" runat="server"></asp:ContentPlaceHolder>

</head>

markup.

<script src='<%= ResolveUrl("~/Scripts/jquery-1.4.1.js") %>'type="text/javascript"></script>

<script src='<%= ResolveUrl("~/Scripts/jquery.tablesorter.min.js") %>'type="text/javascript"></script>

Note: Make sure that you add the closing script tag (</script>) and not the self-closing script tag

(</>). The self-closing tag for the script references is not recognized by the browsers.

Best Practices: For Web Forms applications, you can use the ResolveUrl method, which correctly

resolves the URL relative to the request.

f Task 3: Add Logic to the query and return a random product from the database

1. Remove the default DoWork method and comments from the service class.

[Visual C#]// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat isWebMessageFormat.Json)

// To create an operation that returns XML,

// add [WebGet(ResponseFormat=WebMessageFormat.Xml)],// and include the following line in the operation body:

return;}


[Visual Basic]' To use HTTP GET, add <WebGet()> attribute. (Default ResponseFormat is

WebMessageFormat.Json)

' To create an operation that returns XML,' add <WebGet(ResponseFormat:=WebMessageFormat.Xml)>,' and include the following line in the operation body:

' WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"

<OperationContract()>Public Sub DoWork()

' Add your operation implementation here

End Sub


• In the ProductsService.svc window, select the following code, and then press DELETE.

[Visual C#] // To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is

WebMessageFormat.Json)

// To create an operation that returns XML,// add [WebGet(ResponseFormat=WebMessageFormat.Xml)],

' and include the following line in the operation body:

' WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"<OperationContract()>

Public Sub DoWork()

' Add your operation implementation hereEnd Sub


2. Add the following GetRandomProduct method to the ProductsService.svc file.

[Visual C#]public class ProductsService

{

[OperationContract]public string GetRandomProduct(){

var random = new Random();using (var db = new AdventureWorksEntities()){

var randomNumber = random.Next(1, db.Products.Count() + 1);var randomProduct = (from p in db.Products

where p.ProductID == randomNumberselect new { p.Name, p.ListPrice, p.ProductNumber

}).FirstOrDefault();return new

System.Web.Script.Serialization.JavaScriptSerializer().Serialize(randomProduct);}

}

}

[Visual Basic]Public Class ProductsService

<OperationContract()>Public Function GetRandomProduct() As String

Dim random = New Random()

Using db = New AdventureWorksEntities()Dim randomNumber = random.[Next](1, db.Products.Count() + 1)

Dim randomProduct = (From p In db.ProductsWhere p.ProductID = randomNumberSelect New With {p.Name, p.ListPrice,


Return NewSystem.Web.Script.Serialization.JavaScriptSerializer().Serialize(randomProduct)

End UsingEnd Function

End Class




• In the ProductsService.svc window, add the following code in the ProductsService class.

[Visual C#] [OperationContract]

public string GetRandomProduct()

{

var random = new Random();

int randomNumber = 0;

using (var db = new AdventureWorksEntities()){

int count = 0;

while (count == 0)

{

randomNumber = random.Next(500, 1000);

var query = (from p in db.Products

where p.ProductID == randomNumberselect p);

count = query.Count();}

var randomProduct = (from p in db.Productswhere p.ProductID == randomNumber

select new { p.Name, p.ListPrice, p.ProductNumber

}).FirstOrDefault();

return new

System.Web.Script.Serialization.JavaScriptSerializer().Serialize(randomProduct);

}

}

[Visual Basic] <OperationContract()>

Public Function GetRandomProduct() As StringDim random = New Random()Dim randomNumber As Integer

Using db = New AdventureWorksEntities()Dim count As Integer = 0

While count = 0randomNumber = random.[Next](500, 1000)

Dim query = (From p In db.Products

Where p.ProductID = randomNumberSelect p)

count = query.Count()

End While

Dim randomProduct = (From p In db.Products

Where p.ProductID = randomNumberSelect New With {p.Name, p.ListPrice,


Return New

System.Web.Script.Serialization.JavaScriptSerializer().Serialize(randomProduct)

End Using




End Function

Note: We are invoking the ProductsService from the client side. Hence, we want the returned format

to be XML or Json. For this reason, we are using the JavaScriptSerializer class to serialize the class into

a valid Json format.

f Task 4: Examine the service configuration in the Web.config file



2. Examine the configuration markup in the system.serviceModel element, which has been created by

the Ajax-enabled WCF service project item template.

ProductLabel.

c. In the Properties window, in the Height box, type 14, in the Width box, type 100, in the

Content box, type Products, and then press ENTER.

10. The final result will look something like this:




11. Examine the markup in XAML view.

<UserControl x:Class="AdventureWorksSL.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="400"xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"

Height="400" Width="600">

<Grid x:Name="LayoutRoot" Background="White" Width="600" Height="400">


HorizontalAlignment="Left" Name="CategoriesDataGrid" VerticalAlignment="Top"Width="100" Margin="5,30,0,0" />


HorizontalAlignment="Left" Margin="106,30,0,0" Name="ProductsDataGrid"VerticalAlignment="Top" Width="370" />

<sdk:Label Height="14" HorizontalAlignment="Left" Name="CategoryLabel"

VerticalAlignment="Top" Width="100" Margin="6,1,0,0" Content="Categories" /><sdk:Label Height="14" HorizontalAlignment="Left" Margin="106,1,0,0"

Name="ProductLabel" VerticalAlignment="Top" Width="100" Content="Products" />

</Grid>

</UserControl>

12.

Configure the CategoriesDataGrid control to display the necessary columns returned from theGetProductCategories service method, by adding a DataGrid.Columns element to the

CategoriesDataGrid control.

<sdk:DataGrid AutoGenerateColumns="False" Height="156" HorizontalAlignment="Left"Name="CategoriesDataGrid" VerticalAlignment="Top" Width="100" Margin="5,30,0,0">

<sdk:DataGrid.Columns><sdk:DataGridTextColumn Binding="{Binding ProductCategoryID}" Header="ID"

Visibility="Collapsed" />

<sdk:DataGridTextColumn Binding="{Binding Name}" Header="Name" /></sdk:DataGrid.Columns>




</sdk:DataGrid>

a. In the XAML view, change the self-closing DataGrid element with the Name attribute value of

CategoriesDataGrid, to an opening and closing element.

<sdk:DataGrid AutoGenerateColumns="False" Height="156" HorizontalAlignment="Left"

Name="CategoriesDataGrid" VerticalAlignment="Top" Width="100" Margin="5,30,0,0"> </sdk:DataGrid>

b. In the XAML view, between the opening and closing DataGrid element with the Name attribute

value of CategoriesDataGrid, add the following markup.


<sdk:DataGridTextColumn Binding="{Binding ProductCategoryID}" Header="ID"Visibility="Collapsed" />

<sdk:DataGridTextColumn Binding="{Binding Name}" Header="Name" />

</sdk:DataGrid.Columns>

13. Configure the ProductsDataGrid control to display the necessary columns returned from the

GetProductByCategory service method, by adding a DataGrid.Columns element to the

ProductsDataGrid control.


Margin="106,30,0,0" Name="ProductsDataGrid" VerticalAlignment="Top" Width="370" /><sdk:DataGrid.Columns>

<sdk:DataGridTextColumn Binding="{Binding Name}" Header="Name" />

<sdk:DataGridTextColumn Binding="{Binding ProductNumber}" Header="ProductNumber" />

<sdk:DataGridTextColumn Binding="{Binding Color}" Header="Color" />

<sdk:DataGridTextColumn Binding="{Binding Size}" Header="Size" /></sdk:DataGrid.Columns>

</sdk:DataGrid>

a. In the XAML view, change the self-closing DataGrid element with the Name attribute value of

CategoriesDataGrid, to an opening and closing element.


Margin="106,30,0,0" Name="ProductsDataGrid" VerticalAlignment="Top" Width="370"></sdk:DataGrid>

b. In the XAML view, between the opening and closing DataGrid element with the Name attribute

value of CategoriesDataGrid, add the following markup.


<sdk:DataGridTextColumn Binding="{Binding Name}" Header="Name" /> <sdk:DataGridTextColumn Binding="{Binding ProductNumber}" Header="Product

Number" />

<sdk:DataGridTextColumn Binding="{Binding Color}" Header="Color" /> <sdk:DataGridTextColumn Binding="{Binding Size}" Header="Size" />

</sdk:DataGrid.Columns>

Task 4: Call the services asynchronously

1. In the Designer, double-click the CategoriesDataGrid control.

Note: This creates an event handler named CategoriesDataGrid_SelectionChanged in the

MainPage.xaml.cs or MainPage.xaml.vb code-behind file.




[Visual C#] private void CategoriesDataGrid_SelectionChanged(object sender,SelectionChangedEventArgs e) { }

[Visual Basic] Private Sub CategoriesDataGrid_SelectionChanged(ByVal sender As System.Object, ByVal

e As System.Windows.Controls.SelectionChangedEventArgs) HandlesCategoriesDataGrid.SelectionChanged

End Sub 2. In the MainPage class, create a protected variable for the ProductServiceSLClient object.

[Visual C#]


protected AdventureWorks.ProductServiceSLClient productService = new

AdventureWorks.ProductServiceSLClient();

...

[Visual Basic]

Public Partial Class MainPage Inherits UserControl

Protected productService As New AdventureWorks.ProductServiceSLClient()

... • In the MainPage.xaml.cs or MainPage.xaml.vb window, add the following code at the top of

the MainPage class.

[Visual C#] protected AdventureWorks.ProductServiceSLClient productService = new

AdventureWorks.ProductServiceSLClient();

[Visual Basic] Protected productService As New AdventureWorks.ProductServiceSLClient()

3. In the MainPage class constructor, wire up event handlers for the two Web service methods.

[Visual C#]

public MainPage() { InitializeComponent();

productService.GetProductCategoriesCompleted += new

EventHandler<AdventureWorks.GetProductCategoriesCompletedEventArgs>(productService_GetProductCategoriesCompleted);

productService.GetProductsByCategoryCompleted += new

EventHandler<AdventureWorks.GetProductsByCategoryCompletedEventArgs>(productService_G

etProductsByCategoryCompleted);}




[Visual Basic]

Public Sub New() InitializeComponent()

AddHandler productService.GetProductCategoriesCompleted, AddressOf

productService_GetProductCategoriesCompleted

AddHandler productService.GetProductsByCategoryCompleted, AddressOfproductService_GetProductsByCategoryCompletedEnd Sub

• In the MainPage.xaml.cs or MainPage.xaml.vb window, append the following code to the

constructor in the MainPage class.

[Visual C#]

productService.GetProductCategoriesCompleted += new

EventHandler<AdventureWorks.GetProductCategoriesCompletedEventArgs>(productService_GetProductCategoriesCompleted); productService.GetProductsByCategoryCompleted += new

EventHandler<AdventureWorks.GetProductsByCategoryCompletedEventArgs>(productService_GetProductsByCategoryCompleted);

[Visual Basic]

AddHandler productService.GetProductCategoriesCompleted, AddressOfproductService_GetProductCategoriesCompleted

AddHandler productService.GetProductsByCategoryCompleted, AddressOfproductService_GetProductsByCategoryCompleted

4. Each event handler needs a method to execute once the asynchronous call completes.

[Visual C#]


AdventureWorks.GetProductsByCategoryCompletedEventArgs e) { } void productService_GetProductCategoriesCompleted(object sender,

AdventureWorks.GetProductCategoriesCompletedEventArgs e) { }

[Visual Basic]

Private Sub productService_GetProductCategoriesCompleted(ByVal sender As Object,

ByVal e As AdventureWorks.GetProductCategoriesCompletedEventArgs) End Sub Private Sub productService_GetProductsByCategoryCompleted(ByVal sender As Object,

ByVal e As AdventureWorks.GetProductsByCategoryCompletedEventArgs) End Sub

• In the MainPage.xaml.cs or MainPage.xaml.vb window, append the following code to the

MainPage class.




[Visual C#]

void productService_GetProductsByCategoryCompleted(object sender,AdventureWorks.GetProductsByCategoryCompletedEventArgs e)

{

}

void productService_GetProductCategoriesCompleted(object sender,AdventureWorks.GetProductCategoriesCompletedEventArgs e)

{

}

[Visual Basic]

Private Sub productService_GetProductCategoriesCompleted(ByVal sender As Object,

ByVal e As AdventureWorks.GetProductCategoriesCompletedEventArgs)

End Sub

Private Sub productService_GetProductsByCategoryCompleted(ByVal sender As Object,

ByVal e As AdventureWorks.GetProductsByCategoryCompletedEventArgs)

End Sub

5. When the page loads, the CategoriesDataGrid control must be populated. In the class constructor,

add a call to the service method GetProductCategoriesAsync.

[Visual C#]

public MainPage() {


EventHandler<AdventureWorks.GetProductCategoriesCompletedEventArgs>(productService_Ge

tProductCategoriesCompleted); productService.GetProductsByCategoryCompleted += new


productService.GetProductCategoriesAsync();

}

[Visual Basic]

Public Sub New() InitializeComponent() AddHandler productService.GetProductCategoriesCompleted, AddressOf

productService_GetProductCategoriesCompleted AddHandler productService.GetProductsByCategoryCompleted, AddressOf

productService_GetProductsByCategoryCompleted productService.GetProductCategoriesAsync()

End Sub • In the MainPage.xaml.cs or MainPage.xaml.vb window, append the following code to the

constructor in the MainPage class.

[Visual C#]

productService.GetProductCategoriesAsync();




[Visual Basic]

productService.GetProductCategoriesAsync()

Task 5: Bind the data returned from the services to the grids

1. The initial call to GetProductCategoriesAsync returns to

productService_GetProductCategoriesCompleted. In theproductService_GetProductCategoriesCompleted method, bind the results using the ItemsSource

property returned by the service to the grid.

[Visual C#] void productService_GetProductCategoriesCompleted(object sender,

AdventureWorks.GetProductCategoriesCompletedEventArgs e)

{CategoriesDataGrid.ItemsSource = e.Result;

}

[Visual Basic]

Sub productService_GetProductCategoriesCompleted(sender As Object, e As

AdventureWorks.GetProductCategoriesCompletedEventArgs)CategoriesDataGrid.ItemsSource = e.Result

End Sub

• In the MainPage.xaml.cs or MainPage.xaml.vb window, add the following code to the

productService_GetProductCategoriesCompleted method in the MainPage class.

[Visual C#]

CategoriesDataGrid.ItemsSource = e.Result;

[Visual Basic]

CategoriesDataGrid.ItemsSource = e.Result

2. In the CategoriesDataGrid_SelectionChanged event handler, get the selected category, and retrieve

the products by category.

[Visual C#]

private void CategoriesDataGrid_SelectionChanged(object sender,

SelectionChangedEventArgs e)

{ AdventureWorks.ProductCategory category = CategoriesDataGrid.SelectedItem as

AdventureWorks.ProductCategory;

productService.GetProductsByCategoryAsync(category.ProductCategoryID);}

[Visual Basic]Private Sub CategoriesDataGrid_SelectionChanged(sender As Object, e As

SelectionChangedEventArgs) Dim category As AdventureWorks.ProductCategory =

TryCast(CategoriesDataGrid.SelectedItem, AdventureWorks.ProductCategory)

productService.GetProductsByCategoryAsync(category.ProductCategoryID)

End Sub • In the MainPage.xaml.cs or MainPage.xaml.vb window, add the following code to the

CategoriesDataGrid_SelectionChanged method in the MainPage class.




[Visual C#]

AdventureWorks.ProductCategory category = CategoriesDataGrid.SelectedItem asAdventureWorks.ProductCategory;

productService.GetProductsByCategoryAsync(category.ProductCategoryID);

[Visual Basic]Dim category As AdventureWorks.ProductCategory =

TryCast(CategoriesDataGrid.SelectedItem, AdventureWorks.ProductCategory) productService.GetProductsByCategoryAsync(category.ProductCategoryID)

3. The call to GetProductsByCategoryAsync returns to the

productService_GetProductsByCategoryCompleted method, where the results returned by the

service should be bound to the ItemsSource property of the grid.

[Visual C#]

void productService_GetProductsByCategoryCompleted(object sender,AdventureWorks.GetProductsByCategoryCompletedEventArgs e)

{ ProductsDataGrid.ItemsSource = e.Result;

}

[Visual Basic]

Sub productService_GetProductsByCategoryCompleted(sender As Object, e As

AdventureWorks.GetProductsByCategoryCompletedEventArgs) ProductsDataGrid.ItemsSource = e.Result

End Sub • In the MainPage.xaml.cs or MainPage.xaml.vb window, add the following code to the

productService_GetProductsByCategoryCompleted method in the MainPage class.

[Visual C#]


[Visual Basic]

ProductsDataGrid.ItemsSource = e.Result

4. The final code should like this.

[Visual C#]


protected AdventureWorks.ProductServiceSLClient productService = new

AdventureWorks.ProductServiceSLClient(); public MainPage() {


EventHandler<AdventureWorks.GetProductCategoriesCompletedEventArgs>(productService_GetProductCategoriesCompleted);

productService.GetProductsByCategoryCompleted += new


productService.GetProductCategoriesAsync(); }




private void CategoriesDataGrid_SelectionChanged(object sender,SelectionChangedEventArgs e)

{ AdventureWorks.ProductCategory category = CategoriesDataGrid.SelectedItem as

AdventureWorks.ProductCategory; productService.GetProductsByCategoryAsync(category.ProductCategoryID);

} void productService_GetProductsByCategoryCompleted(object sender,

AdventureWorks.GetProductsByCategoryCompletedEventArgs e) {

ProductsDataGrid.ItemsSource = e.Result; } void productService_GetProductCategoriesCompleted(object sender,

AdventureWorks.GetProductCategoriesCompletedEventArgs e) {

CategoriesDataGrid.ItemsSource = e.Result; }

}

[Visual Basic]

Partial Public Class MainPage Inherits UserControl Protected productService As New AdventureWorks.ProductServiceSLClient() Public Sub New()

InitializeComponent() AddHandler productService.GetProductCategoriesCompleted, AddressOf

productService_GetProductCategoriesCompleted AddHandler productService.GetProductsByCategoryCompleted, AddressOf

productService_GetProductsByCategoryCompleted productService.GetProductCategoriesAsync()

End Sub Private Sub CategoriesDataGrid_SelectionChanged(ByVal sender As System.Object,

ByVal e As System.Windows.Controls.SelectionChangedEventArgs)
