Dim instance As TabControl

public TabPage SelectedTab { get; set; }

    TabPage^ get ();
    void set (TabPage^ value);
}

public TabPage get_SelectedTab ()

Eigenschaftenwert

Eine TabPage, die die derzeit ausgewählte Registerkarte darstellt. Wenn keine Registerkarte ausgewählt ist, ist der Wert NULL (Nothing in Visual Basic).

Hinweise

Die Registerkarte muss sich in der TabPages-Auflistung befinden, wenn sie zur aktuellen Registerkarte werden soll.

Beispiel

Im folgenden Codebeispiel wird ein TabControl mit zwei TabPage-Objekten erstellt. Die SelectedTab-Eigenschaft legt tabPage2 als die derzeit ausgewählte Registerkarte fest.

Verwenden Sie für dieses Beispiel den System.Drawing-Namespace und den System.Windows.Forms-Namespace.
