UIElement::MouseUp Event


Occurs when any mouse button is released over this element.

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

event MouseButtonEventHandler^ MouseUp {
	void add(MouseButtonEventHandler^ value);
	void remove(MouseButtonEventHandler^ value);

This event creates an alias for the Mouse::MouseUp attached event for this class, so that MouseUp is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the MouseUp event are attached to the underlying Mouse::MouseUp attached event and receive the same event data instance.

The MouseUp event is often raised together with either MouseLeftButtonUp or MouseRightButtonUp, which correspond to a release of one of the two standard mouse buttons. MouseLeftButtonUp and MouseRightButtonUp are also routed events, but they are direct routed events, and the appropriate button-specific event is raised when the Mouse::MouseDown event reaches this element along the event route. See Remarks for MouseLeftButtonUp or MouseRightButtonUp.
