Definition

Namespace:
System.Windows System.Windows System.Windows System.Windows
Assembly:
PresentationCore.dll

Occurs when a finger touches the screen while the finger is over this element.

public:
 event EventHandler<System::Windows::Input::TouchEventArgs ^> ^ PreviewTouchDown;
public event EventHandler<System.Windows.Input.TouchEventArgs> PreviewTouchDown;
member this.PreviewTouchDown : EventHandler<System.Windows.Input.TouchEventArgs> 
Public Custom Event PreviewTouchDown As EventHandler(Of TouchEventArgs)

Remarks

By default, the PreviewTouchDown and TouchDown events do not occur until a finger touches the screen and moves. Pressing a finger on the screen and holding it without moving it causes the press and hold behavior of a Stylus. The press and hold behavior is equivalent to a mouse right-click.

To cause the PreviewTouchDown and TouchDown events to occur as soon as a finger touches the screen, set the Stylus.IsPressAndHoldEnabled attached property to false for this element.
