Raises the OnLostFocus(EventArgs) event.

protected:
 override void OnLostFocus(EventArgs ^ e);
protected override void OnLostFocus (EventArgs e);
override this.OnLostFocus : EventArgs -> unit
Protected Overrides Sub OnLostFocus (e As EventArgs)

Parameters

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