Comentarios

La LockAttributes propiedad permite bloquear todos los atributos que especifique.

Para ello, use el Contains método , como se explica en la sección Ejemplo.

Nota

La LockAttributes propiedad permite evitar que se modifiquen los elementos de configuración secundarios del elemento al que se aplica la regla. Use LockItem si desea colocar un bloqueo general en el propio elemento y sus elementos secundarios.

Notas a los desarrolladores de herederos

Si usa las LockAllAttributesExcept propiedades y LockAttributes al mismo tiempo, se aplica la regla más restrictiva.
