What is the use of x:code ?

x:Code is a directive element defined in XAML. An x:Code directive element can contain inline programming code. The code that is defined inline can interact with the XAML on the same page. The following example illustrates inline C# code. Notice that the code is inside the x:Code element and that the code must be surrounded by <CDATA[…]]> to escape the contents for XML, so that an XAML processor (interpreting either the XAML schema or the WPF schema) will not try to interpret the contents literally as XML. [XAML] <Page xmlns=\'http://schemas.microsoft.com/winfx/2006/xaml/presentation\' xmlns:x=\'http://schemas.microsoft.com/winfx/2006/xaml\' x:Class=\'MyNamespace.MyCanvasCodeInline\' > <Button Name=\'button1\' Click=\'Clicked\'>Click Me!</Button> <x:Code><![CDATA[ void Clicked(object sender, RoutedEventArgs e) { button1.Content = \'Hello World\'; } ]]></x:Code> </Page>

How do I create in-line event handlers?

Here are some examples: Example 1: animation.Completed += delegate { // Start the other animation after the end of the previous animation. index++; if (lstDefinitions.Count > index) this.PerformAnimations(index, lstDefinitions); }; Example 2: label.MouseDown += (sender, e) => { Console.WriteLine(\'MouseDown:{0}\', e.OriginalSource); //Not clear why this is needed, but I guess this can effectively bypass // any attempt from the parent control to capture the mouse inside MouseDown handler. e.Handled = true; };
