13. SILVERLIGHT

14. silverlight o a subset of the.net framework and WPF o first introduced as a browser plug-in o.net runtime on multiple platforms (mac, windows) o currently targeted for: o device apps (currently windows phones) o client apps (emphasis on enterprise) o rich media apps (such as streaming video) o reuse code for desktop, web and phone apps! introduction

15. silverlight o code + xaml o controls o layout o data binding o graphics principals

16. code + xaml o xaml is basically a declarative language for object instantiation o xaml is great for UI development. it’s: o standard XML o hierarchical o extensible o declarative o we can do most things both in xaml and in code, but you’ll quickly find that xaml is much more convenient for some tasks

17. code + xaml comparison XAML <Grid x:Name="ContentPanel" Margin="12,0,12,0"> <TextBlock Text="Hello, Windows Phone 7!" Margin="6" HorizontalAlignment="Center" VerticalAlignment="Center" /> C# var tb = new TextBlock(); tb.Text = "Hello, Windows Phone 7!"; tb.HorizontalAlignment = HorizontalAlignment.Left; tb.VerticalAlignment = VerticalAlignment.Top; tb.Margin = new Thickness(6); ContentPanel.Children.Add(tb);

18. code + xaml o controls contain other controls, and some controls are built using other controls o this creates a hierarchical relationship between the controls which we call the visual tree o when you write xaml, the structure of the visual tree is very clear the visual tree

19. demo hello, xaml

20. controls

21. o inherits from FrameworkElement o two main types: o custom control – a reusable, templatable control (e.g. a button) o user control – a way to modularize your application (e.g. employee view) o uses dependency properties and routed events o responds to input (touch, keyboard) anatomy

22. controls o extend CLR properties with: o data binding o change notification o animation o validation o control-tree inheritance dependency properties

23. controls o extend CLR events o can travel along the visual tree: o bubbling or tunneling routed events

24. controls routed events Root Element 1 Element 1.1 Element 2 Element 2.1 Element 2.2 Element 1.2  PreviewMouseDown on Root  PreviewMouseDown on Element 1  PreviewMouseDown on Element 1.2  MouseDown (bubble) on Element 1.2  MouseDown (bubble) on Element 1  MouseDown (bubble) on Root

25. layout basic properties Element Horizontal Alignment Vertical Alignment Container Margin Padding {Min, Max} Height {Min, Max} Width Render Transform

26. layout o Grid o StackPanel o WrapPanel (*) o Canvas * can be found in the silverlight toolkit panels

27. demo layout with panels

28. controls o defines a set of dependency properties and values o similar to CSS in HTML o provides a great way to control the looks of your app from a central location styles

29. controls o completely customize appearance of controls without having to write any code or inherit from the control o all controls have default styles and templates o template editing is easy with Expression Blend templates

30. demo template editing in blend

31. data binding o flow data from a source to a target o source: any CLR object o target: Dependency Property only o modes: one way, two way o supports change notifications o changes to a source object automatically sent to the UI o both property and collection changes are supported

32. data binding o provide a visual representation of an object o the default behavior if no template is specified is to display the Object.ToString() result o use bindings to display data o respond to changes using triggers o can only be written in xaml data templates

33. data binding o use ItemsControl whenever you need to bind to a collection o provide an ItemTemplate to change the visuals of each item o controls that inherit from ItemsControl: o ListBox, ContextMenu, MenuItem, Panorama collections

34. demo data binding

35. o designed specifically with WPF/Silverlight in mind o relies on bindings to retrieve and set data from and to the view model o uses commands to perform operations on the view model o relies on notifications to communicate between the layers o creates a data-driven UI the mvvm pattern Model View View Model business logic and data presentation logic and state UI (and possibly some UI logic)

36. graphics o store images as resources or as content o content is recommended o use the Image control to show them o use WritableBitmap to create images in runtime o you can also use it to capture your screens images

37. graphics o controls inheriting from Shape can be used to create 2D shapes o Rectangle, Ellipse, Line, Polyline, Polygon, Path o Path is the most versatile, accepting a Geometry object which can represent any shape o it is easiest to create shapes using Expression Blend vectors

38. graphics o FrameworkElement has a RenderTransform property which can be assigned to: o TranslateTransform (move) o ScaleTransform o RotateTransform o SkewTransform o CompositeTransform (combine any of the above) o additionally, the Projection property allows creating 3D-like effects transforms

39. graphics o animate dependency property using a Timeline that fits the property type: o DoubleAnimation, ColorAnimation, PointAnimation o use Storyboard to group a few animations together o use an easing function to make the animation look more “real” (e.g. to add elasticity) o it’s easiest to create storyboards in xaml and in Expression Blend animations

40. demo animations

43. WINDOWS PHONE

44. windows phone o application structure o phone-specific controls o sensors and services

45. application structure o App.xaml: application entry point. contains global resources, services, events (startup, shutdown, etc.) and instantiates PhoneApplicationFrame o WMAppManifest.xml: contains application deployment information: capabilities, tasks, icon. o MainPage.xaml: a PhoneApplicationPage that contains the main view of the application. files

46. application structure o PhoneApplicationFrame o PhoneApplicationPage o Grid named “LayoutRoot” o StackPanel named “TitlePanel” o TextBlock named “ApplicationTitle” o TextBlock named “PageTitle” o Grid named “ContentPanel” o you can clear the entire page content and write your own, but for most apps it is recommended to stay within the ‘metro’ guidelines default control tree

47. application structure o just like a web browser, each page in windows phone can be navigated to using the NavigationService by passing a URI o the PhoneApplicationFrame can only display a single page at a time! o the hardware back button can be used to go back to the previous page on the stack o you can pass data to the page using URI query or by placing it in a globally known location (such as the App class) navigation

48. application structure o windows phone can only run one application at a time. so, each time you switch to another application, the current one gets terminated – i.e. tombstoned o your app will get tombstoned if: o you click the start button o you get a call while the app is running o the phone gets locked o the app uses a launcher or a chooser (e.g. use the camera) o you can use the app’s Activated and Deactivated events to handle tombstoning tombstoning

49. demo tombstoning

50. application structure o preferred menu system for your apps o up to 4 buttons, monochrome 62x62 bitmaps o add a button from Blend to get some default bitmaps o get more from http://thenounproject.com o add up to 5 menu items application bar

51. demo application bar

52. phone controls o most of silverlight’s controls have been adjusted to windows phone, supporting touch and templated to the phone’s theme o while some controls such as ComboBox and ToolTip exist on the phone, their use is discouraged

53. phone controls o panoramic applications offer a unique way to view controls, data, and services by using a long horizontal canvas that extends beyond the confines of the screen. o pivot can be used for filtering large datasets, viewing multiple data sets, or switching application views. panorama and pivot

54. demo panorama & pivot

55. sensors o measures acceleration forces such as gravity or the forces caused by moving the sensor o can tell the direction of the earth relative to the phone o use the Accelerometer class to access the sensor o this sensor reports a constant value in the emulator, so it is recommended that you mock its values for testing o possible uses: responding to phone movements in games, bubble levels, etc. accelerometer

56. demo accelerometer

57. sensors o obtain the current location of the phone using the GeoCoordinateWatcher class o you can get the latitude, longitude, altitude and current speed of the device o this sensor is not available in the emulator. use the GpsEmulator project, available at app hub o use the Bing maps control to display a map of the current location geo-location

58. sensors o obtain photos from the camera using the CameraCaptureTask chooser o get a Stream from the chooser and create a BitmapImage from it o the emulator will provide a simple black- and-white image to capture camera

59. demo camera

60. services o allows applications to receive updates in the background (app doesn’t need to be running!) o three types of notifications: o toast – when app is inactive o tile (background, title, count) o raw – directly to the app o you need to create a compatible web service push notifications

61. what’s coming o internet explorer 9 o SQL CE: in-memory local SQL database o multi-tasking and live agents o silverlight 4 o raw camera feed access o tcp/ip sockets o better developer tools o beta sdk shipping this month in version 7.5 (aka “mango”)
