Opmerkingen

Deze id wordt gebruikt door UI Automation clienttoepassingen. UI Automation providers moeten het equivalente veld in GridItemPatternIdentifiers gebruiken.

De patroon-id wordt doorgegeven aan methoden zoals GetCurrentPattern het controlepatroon van belang ophalen van de opgegeven AutomationElement.
