Voorbeelden

 private AutomationElement EnclosingElementFromSelection(AutomationElement target)

    PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document);

    // target --> The root AutomationElement.
    AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);

    TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;

    if (textpatternPattern == null)
    {
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
        return null;
    }

    return currentSelection[0].GetEnclosingElement();
}

Opmerkingen

De ingesloten AutomationElementtekstprovider, meestal de tekstprovider die het tekstbereik levert. Als de tekstprovider echter onderliggende elementen, zoals tabellen of hyperlinks, ondersteunt, kan het insluitende element een afstammeling van de tekstprovider zijn.
