Datagrid / Usercontrol problem

I created a usercontrol that is added to each of my pages. On one of my pages, I have a datagrid inside a table cell. I load the datagrid information fine and I can select a row on the first page. When I go to change the page it does nothing. I stepped through the code and when I click on a different page, the program goes to the usercontrol page_load event. The program doesn't go to the PageIndexChanged event for the datagrid. Anyone know how to fix this?

Thanks
