I. Concepts of WPF and Silverlight Origins of WPF and Silverlight Compared with the winform of the previous generation, WPF has the advantage that it is easier to create beautiful applications.ProgramInterface, but not many changes in other aspects.

Introduction to WPF ControlsWith an introduction to the previous XAML language, we know that XAML is a tree structure, and that WPF controls, as part of the entire XAML tree, are also a tree-shaped structure. Let's look at a simple example."F:\01.Code\01.MyCode\WpfApplication1\WpfApplication1\Resources\. jpg"Width=" -"/> "Red"Foreground="Red"Verticalalignment="Ce

one by one according to this recursive method to form the interface that you see. 1. Basic elements-panel In the previous section, we learned about the WPF layout principle, which can be simply understood as a small control placed in a large control by row or column, while a small control placed in a smaller control according to the same rule. This control that can be placed in other controls is the basic element in the

to design the style of the interface, define the display elements in the interface, and completely separate from the background data. Unconsciously, problem 1 is also resolved.Public partial class PresentationLayerExt: Form {public TextBox ui = new TextBox (); public PresentationLayerExt () {InitializeComponent (); this. Controls. Add (ui );}}PresentationLayerExt Of course, to specify the synchronization relationship, you still need to implement it using code, but not in the presentation layer,

the other elements do not need to process the event again.private void Button_mousedown (object sender, MouseButtonEventArgs e){MessageBox.Show ("button is clicked! ");E.handled = true;}If you want the grid to participate in event processing, you only need to addhandler it.Grid. AddHandler (Grid.mousedownevent, New Routedeventhandler (Grid_mousedown), true);Here I think we should have a general understanding of routed events. Routed events are actually divided into two categories: Bubble events

First, Canvas Layout controls for absolute positioning of neutron elements in WPF Its child elements define the width and height of the element using width and height Use Convas.left (convas.right), Convas.top (Convas.bottom) to define the relative position of the Convas container If Convas.left and Convas.right, Convas.top and Convas.bottom are present at the same time, Convas.left, Convas.top takes precedence For

that the System. timers. timer runs on a different thread then the user interface (UI) thread. in order to access objects on the user interface (UI) thread, it is necessary to post the operation onto the Dispatcher of the user interface (UI) thread using Invoke or BeginInvoke. for an example of using a System. timers. timer, see the Disable Command Source Via System Timer sample. reasons for using a DispatcherTimer opposed to a System. timers. timer

example, if I want to access the button of the main thread in another thread: Private void oneventfired (Object sender, mousebuttoneventargs E){ BTN. Dispatcher. Invoke (new action (delegate {button1.content = "some text ";})); } Assume that oneventfired is being executed by other threads. In the code, an (anonymous) function is executed through the invoke method of BTN. Dispatcher. This function sets buttton1.content. Invoke and begininvoke are in

WPF closes the application method, while wpf closes the application Many people think that closing an Application should be very simple, for example, an Application in Windows form. exit (); method can solve the problem, but do not abuse it in WPF, because the Application class in
