Dear Buddies:

I have three main elements in a WPF program as follow:

1. a UserControl with a Button in it.
2. a UserControl with a TreeView in it.
3. and my MainWindow which has a grid named GridRoot.

when I press the button in the 1st UserControl, one instance of UserControl with TreeView is created. So here the problem is araised. I want to add this object in the GridRoot of MainWindow(
). however, I can not do that. because I donot have access to GridRoot from the 2nd UserControl (because its private and non-static element). How should I do that?

Sincerely Yours
