List View in Update Panel

I have a listview with Datapager to show products. Everything works fine until i wrap the listview in Update Panel.

When i go to the second (or third etc..) page using pagination and select a product, it goes to another page(used Response.redirect). But when i click the browser back button, instead of showing second (or third etc..) page, it is showing the first page.

Without update panel it works fine.

Please let me know if i am unclear with my question.

Any help would be appreciated.

Thanks,

Laxman
