Hinweise

Die CreateWebPartMenu -Methode wird aufgerufen, nachdem das geerbte System.Web.UI.Control.Load -Ereignis eingetreten ist, um das Webpart zum Festlegen der Eigenschaft WebPartMenu zu benachrichtigen.

Beispiele

Das folgende Codebeispiel zeigt eine überschriebene CreateWebPartMenu -Methode, die ein übergeordnetes Menüelement und zwei Menüelemente im Webpartmenü Standard hinzufügt. Es wird davon ausgegangen, dass diese Methode Teil einer WebPart -Klasse, die enthält zwei benutzerdefinierte booleschen Eigenschaften, ParentItemIsVisible und EnableItem1 ist, können Sie steuern, wenn diese Menüelemente im sichtbar und aktiviert sind. Ein Ereignishandler mit dem Namen EventHandlerForItem1 sollte auch erstellt werden.
