Assembly: System.Windows (in System.Windows.dll)
If the item is a UIElement with its own peer as reported by Owner, then a string form of that owner is returned. Next, the container peer (which could be ItemsControlAutomationPeer, ListBoxAutomationPeer, or another class) is used as a possible source. If there is no container peer, but some valid string can be produced that is either the item as a string or a ToString call to it, that string is returned. Finally, if no string can be produced, this method returns a human-readable resource string that implies that there is no information, which automation reports.
