The event data.
The user presses the SPACEBAR.
The user presses ENTER and AcceptsReturn is true for this control.
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.
