Remarks
Notes to Inheritors
If you override OnMouseMove, always call the base implementation in your OnMouseMove 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.
