A KeyEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnKeyDown method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnKeyDown(KeyEventArgs) in a derived class, be sure to call the base class' OnKeyDown(KeyEventArgs) method so that registered delegates receive the event.
