How to access Parent Element of the ItemsControl's Panel?

Here is the situation: I have created an overloaded Canvas object as an
external assembly.
Now I use it as a panel object in ItemsControl:

<Viewbox
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:Custom="clr-namespace:CustomNamespace"
Stretch="Fill">
<ItemsControl>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Custom:CustomCanvas/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
........
</Viewbox>

How can I access that ItemsControl object from my assembly. Thing is
that I define some resources on ItemsControl and I want to use them in
my Canvas Assebmly C# code. On runtime the CustomCanvas has Parent
property set to null, so I'm really interested almost all the day how
to get that damn parent.

I will really appreciate your help with that.

Hi Anton,

Parent refers to the logical tree. Perhaps try checking the visual tree
using the VisualTreeHelper.GetParent method.

TemplatedParent lets you access the itemspresenter, which should give
you access to the itemscontrol via parent or templatedparent.
if you don't expect things to change much, use visualtreehelper.
