UIElement.TouchDown Event

.NET Framework (current version)
 

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

Namespace:   System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

public event EventHandler<TouchEventArgs> TouchDown

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.
