Assembly: System.Windows (in System.Windows.dll)
'Declaration Protected Overrides Sub OnKeyUp ( _ e As KeyEventArgs _ )
protected override void OnKeyUp( KeyEventArgs e )
The event data.
e is nulla null reference (Nothing in Visual Basic).
Notes to Inheritors
If you override OnKeyUp, always call the base implementation in your OnKeyUp 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.
