                                       </StackPanel>
                                   </DataTemplate>
                               </ListBox.ItemTemplate>
                           </ListBox>
                       </StackPanel>
                   </DataTemplate>
               </telerik:RadGridView.HierarchyChildTemplate>
           </telerik:RadGridView>

Now I have to find the listbox in order to bind the objects list to it. How to solve this? Any Help is appriciated.
