Kommentarer

Den här identifieraren används av UI Automation klientprogram. UI Automation providers bör använda motsvarande fält i SelectionPatternIdentifiers.

Den här egenskapen finns inte i SelectionPattern.SelectionPatternInformation och måste hämtas med hjälp GetCurrentPropertyValue av eller GetCachedPropertyValue.
