How to get the Owner of the ContextMenu (from Silverlight 4 toolkit)?

When I use ContextMenu from Silverlight 4 Toolkit I want to get ContextMenu instance's Owner, but it's not available since in ContextMenu class Owner is an internal property. For example, I have a Rectangle put inside a Border. When I right-click a Rectangle (and a context menu appears) I need to change the Rectangle Border's thickness to indicate that the Rectangle is the current element of the parent Grid, for example. So I try to use ContextMenu.Loaded event where I get the ContextMenu (through the sender parameter), but I can't get the Owner of that ContextMenu (i.e. the Rectangle with its Border). And I need that Owner to make its Border thicker. Please help me find the way to do that.

Maybe you mean the PlacementTarget property. – vortexwolf
to vorrtex: I can't find the PlacementTarget property among ContextMenu's members in Silverlight. Is it supposed to be there in Silverlight or is it just there in WPF? – Dmitriyz
@Dmitriyz I've confused Silverlight with WPF. But I know what to do: use reflection and read the private field _owner. – vortexwolf
Reflection doesn't work. It seems that it is impossible to get owner. – vortexwolf
I think also ContextMenu element handles MouseRightButtonDown event of the owner, so I can't even set needed border thickness in that event handler. If I define an event handler for the border it just never goes there. Are there any other ways to keep ContextMenu and still do what I need? – Dmitriyz

The only soultion I found was to set ContextMenu's DataContext to the needed element from code behind. And then to address the element on which the context menu was opened throught that DataContext property.
