Raises the OnMouseLeave(EventArgs) event.

protected:
 override void OnMouseLeave(EventArgs ^ eventargs);

protected override void OnMouseLeave(EventArgs eventargs);

override this.OnMouseLeave : EventArgs -> unit

Protected Overrides Sub OnMouseLeave (eventargs As EventArgs)

Parameters

eventargs: EventArgs

An EventArgs 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 OnMouseLeave 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 OnMouseLeave(EventArgs) in a derived class, be sure to call the base class's OnMouseLeave(EventArgs) method so that registered delegates receive the event.
