TreeWalker.GetPreviousSibling Method (AutomationElement)
Assembly: UIAutomationClient (in uiautomationclient.dll)
The element from which to retrieve the previous sibling.
Return ValueThe previous sibling element, or a null reference (Nothing in Microsoft Visual Basic .NET) if there is no such element.
An AutomationElement can have additional sibling elements that do not match the current view condition and thus are not returned when navigating the element tree.
The structure of the AutomationElement tree changes as the visible user interface (UI) elements on the desktop change. It is not guaranteed that an element returned as the previous sibling element will be returned as the previous sibling on subsequent passes.
