wPF VisualTreeHelper.GetParent returns wrong class?

Question

I have the following XAML defined.

<Popup x:Class="EMS.Controls.Dictionary.MapTip"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"   
    PopupAnimation="Slide"
     AllowsTransparency="True" Placement="Mouse"       
       x:Name="root"                   
      >

    <Popup.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="../Resources/Styles.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Popup.Resources>
    <Viewbox x:Name="viewBox" IsHitTestVisible="True">
        <Grid Background="Transparent" Name="mainGrid">

        </Grid>
    </Viewbox>
</Popup>

If I walk up the visual tree using VisualTreeHelper.GetParent from "mainGrid", I eventually get System.Windows.Controls.Primitives.PopupRoot, but never get the Popup itself. Anyone with a theory on why this is and what I can do about it? I neeed Popup and not PopupRoot.

TIA.

Answer 1

LogicalTreeHelper is unable to reach the Popup as well the best one could do is try using the Name the "PopupRoot" to compare to GetType().Name.
