    SelectionItemPattern pattern = listItem.GetCurrentPattern(SelectionItemPattern.Pattern) as SelectionItemPattern;
    if (pattern == null)
    {
        return null;
    }
    else
    {
        SelectionItemPattern.SelectionItemPatternInformation properties = pattern.Current;
        return properties.SelectionContainer;
    }

Function GetListItemParent(ByVal listItem As AutomationElement) As AutomationElement
    If listItem Is Nothing Then
        Throw New ArgumentException()
    End If
    Dim pattern As SelectionItemPattern = _
        DirectCast(listItem.GetCurrentPattern(SelectionItemPattern.Pattern), SelectionItemPattern)
    If pattern Is Nothing Then
        Return Nothing
    Else
