UIElement::PreviewMouseUp Event


Occurs when any mouse button is released while the mouse pointer is over this element.

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

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

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

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