instance.OnKeyDown(sender, e)

Parameters

sender
An System.Object value that indicates the event sender.
e

Remarks
Raising an event invokes the event handler through a delegate.

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 in a derived class, be sure to call the base class's OnKeyDown method so that registered delegates receive the event.
