Returns the innermost AutomationElement that encloses the text range.

Namespace:   System.Windows.Automation.Text
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public AutomationElement GetEnclosingElement()

Return Value

Type: System.Windows.Automation.AutomationElement

The innermost element enclosing the caller.

The enclosing AutomationElement, typically the text provider that supplies the text range. However, if the text provider supports child elements such as tables or hyperlinks, then the enclosing element could be a descendant of the text provider.

 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();
}
