3 Declarative Programming Layout and Controls Events and Commands Working with Data Session Agenda Styles

4 4 Reference Applications Demo Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

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.

9 9 Declarative Programming: XAML ProductSeach in WPF & Silverlight Surface XAML Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

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 Margin Text Block Padding

14 14 Layout Demo WPF -warehouse\ProductLocation.xaml Silverlight-StoreInformation.xaml (in controls/store) Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

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

20 20 Controls Demo Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

21 Events and Commands Standard.NET Events Routed Events * Commands * * Partial or no support in Silverlight

22 Routed Events Bubbling *  Starts at the current element and bubbles up to the current element’s parent and that elements parent and so on [MouseLeftButtonDown] Tunneling *  Works opposite of bubbling and starts at the root element and works down to the originating element [PreviewMouseLeftButtonDown] Direct  Works like standard.NET event handling with only direct handlers being notified of events [Click] * Partial or no support in Silverlight

23 Commands Logical action that can be invoke in several ways Based on the RoutedCommand Class Uses both event tunneling [PreviewExecuteEvent] and event bubbling [ExecuteEvent] Not supported in Silverlight

24 24 Events and Commands Demo Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

25 Working with Data Overview Simple Data Binding Complex Data Binding

26 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

27 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

28 Complex Data Binding Binding to Lists Supports two-way data binding to list if list inherits from ObservableCollection Data Templates Sorting Filtering Master/Detail/Detail

29 29 Working with Data Demo Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

30 Adding Style to Your Application Overview Resources * Triggers * * Partial or no support in Silverlight

31 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

32 Style Examples

33 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

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

35 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

36 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

37 37 Adding Style to Your Application Tim Huckaby CEO, InterKnowlogy Microsoft RD & MVP

38 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.
