Provides class handling for the KeyUp routed event that occurs when the user releases a key while this control has focus.
Assembly: PresentationFramework (in PresentationFramework.dll)
This implementation marks the KeyUp event as handled by setting the Handled property of the event data to true when the user releases the SPACEBAR. Otherwise, this implementation does not change the handled state (the Handled property) of the KeyUp event data.Notes to Inheritors
If you override , always call the base implementation in your implementation. Failure to call the base implementation prevents base classes from handling the event with a class handler, which might change the run-time behavior of the final class. You can call the base implementation either before or after your special handling, depending on your requirements.
