Uwagi

Ten identyfikator jest używany przez aplikacje klienckie automatyzacji interfejsu użytkownika. automatyzacja interfejsu użytkownika dostawcy powinni użyć odpowiedniego pola w pliku MultipleViewPatternIdentifiers.

Ta właściwość nie jest obecna w MultipleViewPattern.MultipleViewPatternInformation elemecie i musi zostać pobrana przy użyciu polecenia GetCurrentPropertyValue lub GetCachedPropertyValue.
