Remarks

This identifier is used by UI automation client applications. UI Automation providers should use the equivalent field in MultipleViewPatternIdentifiers.

This property is not present in MultipleViewPattern.MultipleViewPatternInformation and must be retrieved by using GetCurrentPropertyValue or GetCachedPropertyValue.
