Nested grids and listviews data binding problem

Question

Here is the scenario.

I have a telerik radgrid which loads a user control inside nested template. An id gets binded in the declaration.

The user control (Control1) contains a listview. Inside the item template for the listview, there is another user control which also 2 IDs databinded. ClientId and ServiceId.

This user cootrol (Control2) contains a gridview which gets databinded in the code behind.

What is the correct way to databind all this? I am doing it on PageLoad and checking for postback but a problem occurs when it is postback nothing gets databound, but if I remove that, Control2 loses its actions and nothing happens when you edit the gridview.
