Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie den Stil der Unterelemente eines ListViewItem durch die Verwendung der ListView.TopItem -Eigenschaft und der ResetStyle -Methode zurücksetzen. Fügen Sie zum Ausführen des Beispiels den folgenden Code in ein Formular ein, das eine Schaltfläche mit dem Namen Button1enthält, und rufen Sie die InitializeListView -Methode im Konstruktor oder Load der Ereignisbehandlungsmethode des Formulars auf.
