Комментарии

Свойство LockElements позволяет заблокировать все указанные элементы.The LockElements property allows you to lock all the elements you specify.

Для этого используется метод Contains, как описано в следующем примере.To do that, you use the Contains method, as explained in the next example.

Примечание

Свойство LockElements позволяет предотвратить изменение дочерних элементов конфигурации элемента, к которому применяется правило.The LockElements property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. Используйте LockItem, если хотите поместить общую блокировку на сам элемент и его дочерние элементы.Use LockItem if you want to put a general lock on the element itself and its child elements.
