Occurs when a key is released while focus is on this element.
Assembly: PresentationCore (in PresentationCore.dll)
This event creates an alias for the Keyboard.KeyUp attached event for this class so that is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying Keyboard.KeyUp attached event and receive the same event data instance.
