Hinweise

Das ItemInserted -Ereignis wird ausgelöst, wenn auf eine INSERT DetailsView -Schaltfläche im-Steuerelement geklickt wird, aber nach dem Einfügevorgang.The ItemInserted event is raised when an Insert button within the DetailsView control is clicked, but after the insert operation. Dies ermöglicht Ihnen die Bereitstellung eines Ereignis Handlers, der eine benutzerdefinierte Routine ausführt, z. b. das Überprüfen der Ergebnisse des Einfügevorgangs, wenn dieses Ereignis auftritt.This allows you to provide an event handler that performs a custom routine, such as checking the results of the insert operation, whenever this event occurs.

Ein DetailsViewInsertedEventArgs -Objekt wird an den-Ereignishandler übermittelt, mit dem Sie die Anzahl der betroffenen Zeilen und ggf. aufgetretenen Ausnahmen ermitteln können.A DetailsViewInsertedEventArgs object is passed to the event handler, which allows you to determine the number of rows affected and any exceptions that might have occurred. Sie können auch angeben, ob die Ausnahme im Ereignishandler behandelt wurde, indem Sie ExceptionHandled die-Eigenschaft festlegen.You can also indicate whether the exception was handled in the event handler by setting the ExceptionHandled property. Um das Steuerelement im Einfügemodus nach einem Einfügevorgang beizubehalten true, legen Sie die KeepInInsertMode -Eigenschaft auf festTo keep the control in insert mode after an insert operation, set the KeepInInsertMode property to true.

Weitere Informationen zum Behandeln von Ereignissen finden Sie unter behandeln und Auslösen von Ereignissen.For more information about how to handle events, see Handling and Raising Events.
