Control.KeyUp Event
.NET Framework (current version)
Occurs when a key is released while the control has focus.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Key events occur in the following order:
To handle keyboard events only at the form level and not enable other controls to receive keyboard events, set the KeyPressEventArgs.Handled property in your form's KeyPress event-handling method to true. Certain keys, such as the TAB, RETURN, ESC, and arrow keys are handled by controls automatically. To have these keys raise the KeyUp event, you must override the IsInputKey method in each control on your form. The code for the override of IsInputKey would need to determine if one of the special keys is pressed and return a value of true.
