Exemples

 private AutomationElement EnclosingElementFromSelection(AutomationElement target)
{
    // Specify the control type we're looking for, in this case 'Document'
    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;
    }
    TextPatternRange[] currentSelection = textpatternPattern.GetSelection();

    return currentSelection[0].GetEnclosingElement();
}

Private Function EnclosingElementFromSelection(ByVal target As AutomationElement) As AutomationElement
    ' Specify the control type we're looking for, in this case 'Document'
    Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)

    ' target --> The root AutomationElement.
    Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)

    Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)

Remarques

AutomationElementEnglobant , généralement le fournisseur de texte qui fournit la plage de texte. Cependant, si le fournisseur de texte prend en charge des éléments enfants comme des tables ou des liens hypertexte, l'élément englobant peut être un descendant du fournisseur de texte.
