Declarative Programming
• XAML replaces code• Attributes control Layout and Style• Event handlers wired-up in XAML• Declarative Data Binding
What the heck is XAML?• Separates the front-end from the back-end• Simple declarative programming language suitable for
constructing and initializing .NET Objects• Usually the most concise way to represent user
interfaces (or other hierarchies of objects)• Doesn’t need a compile to render• The language that almost all WPF related tools emit
Sample XAML
Runs in a WPF Application:
Runs in the Browser::
Declarative Programming Gotcha(s), tips & tricks
• Not all XAML is created equal• Silverlight was designed to be a small subset
of WPF not a direct port• Surface works with gestures so unique
versions of some controls are required• The Surface SDK is going to permeate WPF
and Silverlight to provide a consistent API for touch across the stack.

Layout Overview
• Content rendering flows inside parent• Fixed positioning (Canvas) is seldom used• Panels are used to house content• Margins and Padding over fixed size
Panels (ALL)• StackPanel
• Arranges child elements into a single line that can be oriented horizontally or vertically.
• Grid• A flexible grid area that consists of columns and rows.
• Canvas• An area within which you can explicitly position child
elements by using coordinates that are relative to the Canvas area.
Panels (WPF and Surface)• WrapPanel
• Positions child elements in sequential position from left to right, breaking content to the next line at the edge of the containing box.
• DockPanel• An area where you can arrange child elements either
horizontally or vertically, relative to each other.
Positioning
• Horizontal and Vertical Alignment• Margin• Padding

Controls Overview
• Not all controls are created equal• Silverlight is a subset of WPF so certain
controls have not ported over yet• Surface relies on touch so it has unique
versions of some controls
Standard Common Controls
• TextBox• Button• CheckBox / ComboBox• Image• ListBox• Tab
WPF Controls
• Menu and Toolbar• TextBlock• InkCanvas / InkPresenter• Expander• TreeView• DocumentViewer• UniformGrid
Silverlight Controls
• DataGrid• Calendar• ProgressBar
Surface Controls
• ScatterView• Menu• TagVisualizer• InkCanvas

Working with Data
• Overview• Simple Data Binding• Complex Data Binding
Data Binding Overview
• Simple Field level Data Binding• Complex Data Binding to multiple controls at a
time (Master/Detail/Detail)• Client-Side Sorting and Filtering• Support for binding to Objects, XML and
Relational data sources
Simple Data Binding
• Simple Data Binding using Business Objects• Support for two-way synchronization in simple
objects via the INotifyPropertyChanged interface
• Implicit and Declarative binding via the DataContext
Complex Data Binding
• Binding to Lists• Supports two-way data binding to list if list
inherits from ObservableCollection<T>• Data Templates• Sorting• Filtering• Master/Detail/Detail

Adding Style to Your Application
• Overview• Resources *• Triggers *
* Partial or no support in Silverlight
Styles Overview
• What are styles?• Problems they address in WinForms 2.0
– Styling controls one at a time– Unnecessary Custom Control Creation
• Similarities to Cascading Style Sheets– Inline declaration– Page level declaration– Separate file declaration
Style Examples
Resources
• Static Resources– Loaded when Window or Page Loads– Leads to slower page loading– Changes to underlining values are not propagated
• Dynamic Resources *– More overhead to allow for constant updates– Can only be used to set dependency properties– Can potentially improve Page and Window load time
* Not supported in Silverlight
Resource Dictionary
• Contains hash table of resources• Great way to organize resources• Resource.MergedDictionaries combines many
different file based resources *
* Not supported in Silverlight
Triggers
• Setters that are set based on one or more conditions
• Three Types of Triggers– Property – Invoked when the value of a
dependency property changes– Data – Invoked when the value of a plain .NET
property changes– Event – Invoked when a routed event changes
Not supported in Silverlight
The Silverlight Visual State Manager
• Alternative to Triggers in Silverlight• Promotes separation between UI and code• Controls have States and State Groups• States within a State Group are immutable• Fully supported in Blend
Not supported in WPF

Summary• Layout in XAML is flexible• Each technology has it’s own set of controls• Data Binding is rich & supports many data types• Styles bring life to your applications• The learning curve can be steep, but is worth it.• Download all my resources and dedicate some time to
learn.
