Raises the KeyUp event.

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

Parameters

e
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' OnKeyUp(KeyEventArgs) method so that registered delegates receive the event.
