Associate a WPF TreeView with a Common View Model

Question

I have a usercontrol that contains a TreeView control. I am using the MVVM pattern. I want to reuse this user control in different windows, each time binding the usercontrol to another datacontext.

   <UserControl Name="UserControl1".......>

      ..............

        <TreeView ItemSource={Binding ...}...>


             <HierarchicalDataTemplate...........\>

        </TreeView>

      .............. 

   </UserControl>

In window 1, I want to bind List<ObjectA>to a TreeView.

In window 2, I want to bind List<ObjectB>to a TreeView.

Is it possible to write a generic ViewModel for this user control so that I can bind different data types to a TreeView ?? If my question is not understood, please let me know.
