Kommentarer
Den här identifieraren används av klientprogram för användargränssnittsautomatisering. UI Automation providers bör använda motsvarande fält i MultipleViewPatternIdentifiers.
Den här egenskapen finns inte i MultipleViewPattern.MultipleViewPatternInformation och måste hämtas med hjälp GetCurrentPropertyValue av eller GetCachedPropertyValue.
