ButtonBase.OnKeyDown Method (KeyEventArgs)
This API supports the product infrastructure and is not intended to be used directly from your code.
Raises the OnKeyUp event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
Themethod 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.
Do not callif the button is disabled (this includes calls to the base class's method when you override in a derived class). When disabling the button in an override of , call the base class's method before disabling the button, or do not call it at all.
Notes to Inheritors:
When overridingin a derived class, be sure to call the base class's method so that registered delegates receive the event.
