4. Canvas –The Best Thing To Draw In <Windowx:Class="CanvasDemo.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Canvas Demo" Height="150" Width="250"> <CanvasBackground="Yellow"> </Canvas> </Window>

5. Panel <Window x:Class="PanelDemo.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Panel Demo" Width="250" Height="150"> <Canvas Name="MyCanvas"> <Ellipse Canvas.Left="10" Canvas.Top="5" Width="100" Height="100" Stroke="Black" Fill="Red"/> <Ellipse Canvas.Left="60" Canvas.Top="5" Width="100" Height="100" Stroke="Black" Fill="Yellow"/> <Ellipse Canvas.Left="110" Canvas.Top="5" Width="100" Height="100" Stroke="Black" Fill="Green"/> </Canvas> </Window>

6. Panel –From Code Behind private void Window_Loaded(object sender, RoutedEventArgse) { Ellipse ellipse= new Ellipse(); ellipse.Width= 200; ellipse.Height= 50; ellipse.Stroke= Brushes.Black; ellipse.Fill= Brushes.Blue; MyCanvas.Children.Add(ellipse); Canvas.SetLeft(ellipse, 10); Canvas.SetTop(ellipse, 30); }

7. Ellipse

8. Rectangle

9. Scaling Shapes with a Viewbox <ViewboxGrid.Row="1" HorizontalAlignment="Left" > <Canvas> </Canvas> </Viewbox>

10. Line <Line Stroke="Blue" X1="0" Y1="0" X2="10" Y2="100“ Canvas.Left="5" Canvas.Top="100"> </Line>

11. PolyLine

12. PolyLine •StrokeDashArray="2 1"

13. Bézier Curves

14. Brushes

15. Transparency

16. Transparency

17. BlurEffect <Button Content="Blurred (Radius=2)" Padding="5" Margin="3"> <Button.Effect> <BlurEffectRadius="2"></BlurEffect> </Button.Effect> </Button>

18. Transforming Shapes

19. Transforming Shapes

20. WPF Content Heaven

25. Positioning in Layouts

26. Positioning public MainWindow() { InitializeComponent(); TextBoxt = new TextBox(); t.Text= "Hi"; t.RenderTransform= new TranslateTransform(10, 10); grid.Children.Add(t); }

27. Positioning

28. Positioning Ellipse ellipse= new Ellipse { Width = width, Height = height }; ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY); Ellipse ellipse= new Ellipse { Width = width, Height = height }; double left = desiredX; double top = desiredY; ellipse.Margin= new Thickness(left, top, 0, 0); Ellipse ellipse= new Ellipse { Width = width, Height = height }; canvas.SetLeft(ellipse, desiredX); canvas.SetTop(ellipse, desiredY);

29. Positioning –Transforms

30. Ellipse ellipse= new Ellipse { Width = width, Height = height }; ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY); Positioning Ellipse ellipse= new Ellipse { Width = width, Height = height }; ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY); ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY);

31. Ellipse ellipse= new Ellipse { Width = width, Height = height }; ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY); Positioning Ellipse ellipse= new Ellipse { Width = width, Height = height }; ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY); ellipse.RenderTransform= new TranslateTransform(desiredX,desiredY);

32. Routed Events

33. Routed Events Routed events normally appear as pair. The first is a tunnellingevent calledPreviewMouseDownand the second is the bubbling calledMouseDown. They don't stop routing if they reach an event handler. To stop routing then you have to set e.Handled= true;

34. Routed Events •Tunneling –The event is raised on the root element and navigates down to the visual tree until it reaches the source element or until the tunneling is stopped by marking the event as handeld. By naming convention it is calledPreview...and appears before corresponding bubbling event. •Bubbling –The event is raised on the source element and navigates up to the visual tree until it reaches the root element or until the bubbling is stopped by marking the event as handled. The bubbling event is raised after the tunneling event. •Direct –The event is raised on the source element and must be handled on the source element itself. This behavior is the same as normal.NET events.

35. Multi-touch Input

39. Drag-and-Drop

40. Drag-and-Drop nice task!

41. Drag-and-Drop •With, private void lblTarget_Drop(object sender, DragEventArgse) { ((Label)sender).Content = e.Data.GetData(DataFormats.Text); }

42. Drag-and-Drop

43. Drag-and-Drop Shapes

44. Drag-and-Drop Shapes •Let’s have just a rectangle names “myRectangle”

45. Drag-and-Drop Shapes private boolIsDragging= false; private void Rect_MouseDown(object sender, MouseButtonEventArgse) { Rectangle rectangle= (Rectangle)sender; IsDragging= true; } private void Rect_PreviewMouseMove(object sender, MouseEventArgse) { if (IsDragging) { Canvas.SetLeft(myRectangle, e.GetPosition(canvas).X -myRectangle.Width/2); Canvas.SetTop(myRectangle, e.GetPosition(canvas).Y -myRectangle.Height/2); } } private void Rect_PreviewMouseUp(object sender, MouseButtonEventArgse) { if (IsDragging) { Canvas.SetLeft(myRectangle, e.GetPosition(canvas).X -myRectangle.Width/2); Canvas.SetTop(myRectangle, e.GetPosition(canvas).Y -myRectangle.Height/2); IsDragging= false; } }

46. Binding

47. WPF Content HeavenBinding and MVVM

48. MVVMModel-View View-Model

49. Visit and know more about http://msdn.microsoft.com/en-us/library/ff648465.aspx Prism provides guidance to help you more easily design and build, flexible, and easy-to-maintain client business apps that run on Windows Runtime, Windows Presentation Foundation (WPF) desktop, Silverlight, or Windows Phone 7. These apps may start small and evolve over time. Visit also: http://compositewpf.codeplex.com/
