Description
OnKeyDown event dispatcher.
Key
specifies the key on the keyboard.
KeyChar
specifies the character code.
Shift
indicates which shift keys--SHIFT, CTRL, ALT, and CMD (only for Mac)--were down when the specified key was pressed with the control in focus.
KeyDown is automatically called each time keys are pressed with the control in focus.
Override the protected KeyDown method to provide other responses when a key is down while the control has keyboard focus.
