UpdatePanel inside ListView

I have a web page with a TabContainer control in it.  The master page has a Toolscript Manager on it for use in all the pages.  I have a ListView inside one of the tabs of the TabContainer and would like to use an UpdatePanel inside of the InsertItemtemplate of that ListView.  I put the UpdatePanel inside the template but it did not work 9continued to do a full postback).  I even tried it around the entire ListView but neither worked.  What do I need to do to get this to work and not postback the full page?  Thanks.
