Delegate

EventHandler<TEventArgs> of type TouchEventArgs.

  • The corresponding tunneling event is PreviewTouchDown.

  • Override OnTouchDown to implement class handling for this event in derived classes.

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.
