Hinweise
Ein TaxonomyWebTaggingControl -Objekt ist ein Websteuerelement, das einer Seite hinzugefügt werden kann, damit ein Benutzer eine oder mehrere Taxonomie Term -Objekt von einem bestimmten TermSet Objekt oder von einem gesamten TermStore Objekt auswählen kann.
Dieses Steuerelement wird sichergestellt, dass alle Bedingungen gelten, ist dies nicht der Fall ist, erfordert es Validierung der Benutzer, wenn einen ungültigen Ausdruck gefunden. Wenn die TermStore oder TermSet -Verbindung kann nicht hergestellt werden, wird die TaxonomyWebTaggingControl deaktiviert.
