Comentarios

La propiedad LockAttributes permite bloquear todos los atributos que se especifiquen.The LockAttributes property allows you to lock all the attributes you specify.

Para ello, use el método Contains, como se explica en la sección ejemplo.To do that you use the Contains method, as explained in the Example section.

Nota

La propiedad LockAttributes permite evitar que se modifiquen los elementos de configuración secundarios del elemento al que se aplica la regla.The LockAttributes property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. Use LockItem si desea colocar un bloqueo general en el propio elemento y sus elementos secundarios.Use LockItem if you want to put a general lock on the element itself and its child elements.

Notas a los desarrolladores de herederos

Si usa las propiedades LockAllAttributesExcept y LockAttributes al mismo tiempo, se aplica la regla más restrictiva.If you use the LockAllAttributesExcept and LockAttributes properties at the same time, the most restrictive rule applies.
