UIElement.PreviewTouchDown Event

Definition

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

public event EventHandler<System.Windows.Input.TouchEventArgs> PreviewTouchDown;

Event Type

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.
