How to get a object parent ? ( object, which is content of expander )
===

To specify my question more, let's say, i have a expander control and its content is a grid.
I have a handle to the grid only and i would like to get the grid parent or a control, which contain that grid.

if i try to get a parent, i will get real parent, but not a control, which is a content of the expander.

thank you
