Description

OnKeyUp event dispatcher.

KeyUp provides a response when a key is released while the control has keyboard focus. KeyUp calls the OnKeyUp event handler if one is assigned.

A control calls KeyUp in response to any key-up messages, decoding the message parameters into the key code, character code, and shift state. The control passes them in the Key, KeyChar, and Shift parameters, respectively:

• Key is the scan code of the released keyboard key.
• KeyChar is the character code of the released key.
• Shift indicates which shift keys--SHIFT, CTRL, ALT, and CMD (only for Mac)--were down when you release the previously pressed key with the control in focus.

Override the protected KeyUp method to provide other responses when a key is released while the control has keyboard input focus.
