Creating Metro (Microsoft UI) app for Windows 8 on WPF+C#, I met difficulty with PointerPressed event on a button. Event doesn't happen when i perform left-click (by mouse), but it happens in case with right-click or tap. So what's wrong with that event? for example

 <Button x:Name="Somebutton"  Width="100" Height="100"
PointerPressed="Somebutton_PointerPressed"/>

推荐答案

解决方案非常简单:这些事件必须通过 AddHandler 方法而不是通过 XAML 来处理.

The solution is pretty simple: these events have to be handled not through XAML but thorugh AddHandler method.

SomeButton.AddHandler(PointerPressedEvent, 
new PointerEventHandler(SomeButton_PointerPressed), true);
