Hinweise

Ein LinkLabel Steuerelement weist nicht automatisch darauf zurück, dass ein Link ein besuchter Link ist. Um den Link als besuchter Link anzuzeigen, können Sie den Wert dieser Eigenschaft true auf einen Ereignishandler für das Klickereignis des LinkLabelKlickens festlegen. Ein besuchter Link wird mithilfe der farbe angezeigt, die in der VisitedLinkColor Eigenschaft des ToolStripLabel Steuerelements angegeben ist.
