Remarques

La LockAllAttributesExcept propriété vous permet de verrouiller tous les attributs à la fois, à l’exception de celui que vous spécifiez. Pour ce faire, utilisez la Contains méthode , comme expliqué dans la section Exemple.

Notes

La LockAllAttributesExcept propriété vous permet d’empêcher la modification des éléments de configuration enfants de l’élément auquel vous appliquez la règle. Utilisez la LockItem propriété si vous souhaitez placer un verrou général sur l’élément parent lui-même et ses éléments enfants.

Notes pour les héritiers

Si vous utilisez les LockAllAttributesExcept propriétés et LockAttributes en même temps, la règle la plus restrictive s’applique.
