Comentarios

Este identificador lo usan las aplicaciones cliente de Automatización de la interfaz de usuario. Automatización de la interfaz de usuario proveedores deben usar el campo equivalente en GridItemPatternIdentifiers.

El identificador de patrón se pasa a métodos como GetCurrentPattern para recuperar el patrón de control de interés del especificado AutomationElement.
