override this.OnCommandChanged : EventArgs -> unit
Protected Overridable Sub OnCommandChanged (e As EventArgs)

Remarks

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

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