Beispiele

Das folgende Beispiel veranschaulicht das Registrieren einer DesignerEventHandler und behandeln die DesignerCreated und DesignerDisposed Ereignisse.The following example demonstrates registering a DesignerEventHandler and handling the DesignerCreated and DesignerDisposed events.

public:
   void LinkDesignerEvent( IDesignerEventService^ eventService )
   {
      // Registers an event handler for the DesignerCreated and DesignerDisposed events.
      eventService->DesignerCreated += gcnew DesignerEventHandler(
         this, &DesignerEventHandlerExample::OnDesignerEvent );
      eventService->DesignerDisposed += gcnew DesignerEventHandler(
         this, &DesignerEventHandlerExample::OnDesignerEvent );
   }

private:
   void OnDesignerEvent( Object^ sender, DesignerEventArgs^ e )
   {
      // Displays designer event information on the console.
      Console::WriteLine( "Name of the root component of the created or disposed designer: " +
         e->Designer->RootComponentClassName );
   }
public void LinkDesignerEvent(IDesignerEventService eventService)
{                                   
    // Registers an event handler for the DesignerCreated and DesignerDisposed events.
    eventService.DesignerCreated += new DesignerEventHandler(this.OnDesignerEvent);
    eventService.DesignerDisposed += new DesignerEventHandler(this.OnDesignerEvent);            
}

private void OnDesignerEvent(object sender, DesignerEventArgs e)
{
    // Displays designer event information on the console.
    Console.WriteLine("Name of the root component of the created or disposed designer: "+e.Designer.RootComponentClassName);
}
Public Sub LinkDesignerEvent(ByVal eventService As IDesignerEventService)
    ' Registers an event handler for the DesignerCreated and DesignerDisposed events.
    AddHandler eventService.DesignerCreated, AddressOf Me.OnDesignerEvent
    AddHandler eventService.DesignerDisposed, AddressOf Me.OnDesignerEvent
End Sub

Private Sub OnDesignerEvent(ByVal sender As Object, ByVal e As DesignerEventArgs)
    ' Displays designer event information on the console.
    Console.WriteLine(("Name of the root component of the created or disposed designer: " + e.Designer.RootComponentClassName))
End Sub

Hinweise

Beim Erstellen eines DesignerEventHandler-Delegaten bestimmen Sie die Methode für die Ereignisbehandlung.When you create a DesignerEventHandler delegate, you identify the method that will handle the event. Um dem Ereignishandler das Ereignis zuzuordnen, fügen Sie dem Ereignis eine Instanz des Delegaten hinzu.To associate the event with your event handler, add an instance of the delegate to the event. Der Ereignishandler wird bei jedem Eintreten des Ereignisses aufgerufen, sofern der Delegat nicht entfernt wird.The event handler is called whenever the event occurs, unless you remove the delegate. Weitere Informationen zu den Ereignishandlerdelegaten, finden Sie unter behandeln und Auslösen von Ereignissen.For more information about event-handler delegates, see Handling and Raising Events.
