In het volgende voorbeeld ziet u hoe u de LinkLabel.LinkBehavior eigenschap instelt met behulp van de LinkBehavior opsomming. Ook ziet u hoe u de LinkLabel.LinkColoren LinkVisitedText eigenschappen instelt. Als u dit voorbeeld wilt uitvoeren, plaatst u dit in een leeg formulier en roept u de InitializeLinkLabel-methode aan vanuit de constructor of de methode Laden van het formulier.
