Assembly: System.Windows.Forms (in system.windows.forms.dll)
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnKeyPress 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 OnKeyPress in a derived class, be sure to call the base class's OnKeyPress method so that registered delegates receive the event.
