Raises the EnabledChanged event.

protected:
 virtual void OnEnabledChanged(EventArgs ^ e);

protected virtual void OnEnabledChanged (EventArgs e);

abstract member OnEnabledChanged : EventArgs -> unit
override this.OnEnabledChanged : EventArgs -> unit

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