ListObject.Change-Ereignis

Tritt auf, wenn Änderungen im ListObject-Steuerelement auftreten.

Namespace:  Microsoft.Office.Tools.Excel
Assembly:  Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)

Syntax

'Declaration
Event Change As ListObjectChangeHandler
event ListObjectChangeHandler Change

Hinweise

Das Ereignis wird ausgelöst, wenn das ListObject-Steuerelement entweder durch eine programmgesteuerte Änderung oder durch eine Benutzerinteraktion geändert wird.

Dieses Ereignis tritt nicht auf, wenn sich Zellen während einer Neuberechnung ändern.

Beispiele

Im folgenden Codebeispiel werden ein ListObject und ein Change-Ereignishandler erstellt. Zum Auslösen des Change-Ereignisses müssen Sie einer Zelle im ListObject Text hinzufügen und die EINGABETASTE drücken.
