Examples
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)
If (textpatternPattern Is Nothing) Then
Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
Return Nothing
End If
Dim currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
Return currentSelection(0).GetEnclosingElement()
End Function
Remarks
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.
