UIElement.KeyUp Event


Occurs when a key is released while focus is on this element.

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

public event KeyEventHandler KeyUp

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