Commenti

Il LockAttributes proprietà consente di bloccare tutti gli attributi specificati.The LockAttributes property allows you to lock all the attributes you specify.

Per farlo, Usa il Contains metodo, come illustrato nella sezione esempio.To do that you use the Contains method, as explained in the Example section.

Nota

Il LockAttributes proprietà consente di evitare che l'elemento figlio gli elementi di configurazione dell'elemento a cui è applicata la regola da modificare.The LockAttributes property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. Usare LockItem se si desidera impostare un blocco generale sull'elemento stesso e i relativi elementi figlio.Use LockItem if you want to put a general lock on the element itself and its child elements.

Note per gli eredi

Se si usa la LockAllAttributesExcept e LockAttributes proprietà nello stesso momento, la regola più restrittiva viene applicata.If you use the LockAllAttributesExcept and LockAttributes properties at the same time, the most restrictive rule applies.
