5. Declarative Programming • XAML replaces code • Attributes control Layout and Style • Event handlers wired-up in XAML • Declarative Data Binding

6. 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

7. Sample XAML Runs in a WPF Application: Runs in the Browser::

8. 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.

10. 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

11. 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.

12. 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.

13. Positioning • Horizontal and Vertical Alignment • Margin • Padding Padding Margin Text Block Text Block

15. 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

16. Standard Common Controls • TextBox • Button • CheckBox / ComboBox • Image • ListBox • Tab

17. WPF Controls • Menu and Toolbar • TextBlock • InkCanvas / InkPresenter • Expander • TreeView • DocumentViewer • UniformGrid

18. Silverlight Controls • DataGrid • Calendar • ProgressBar

19. Surface Controls • ScatterView • Menu • TagVisualizer • InkCanvas

21. Working with Data • Overview • Simple Data Binding • Complex Data Binding

22. 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

23. 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

24. 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

26. Adding Style to Your Application • Overview • Resources * • Triggers * * Partial or no support in Silverlight

27. 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

28. Style Examples

29. 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

30. Resource Dictionary • Contains hash table of resources • Great way to organize resources • Resource.MergedDictionaries combines many different file based resources * * Not supported in Silverlight

31. 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

32. 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

34. 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.
