Definition

Raises the OnKeyUp(KeyEventArgs) event.

protected:
 override void OnKeyUp(System::Windows::Forms::KeyEventArgs ^ kevent);
protected override void OnKeyUp (System.Windows.Forms.KeyEventArgs kevent);
override this.OnKeyUp : System.Windows.Forms.KeyEventArgs -> unit
Protected Overrides Sub OnKeyUp (kevent As KeyEventArgs)

Parameters

kevent
KeyEventArgs KeyEventArgs KeyEventArgs KeyEventArgs

A KeyEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnKeyUp 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 OnKeyUp(KeyEventArgs) in a derived class, be sure to call the base class's OnKeyUp(KeyEventArgs) method so that registered delegates receive the event.
