UpdatePanel and PostBackUrl

I have a GridView in an UpdatePanel so paging the resultset will partial render and I have a Update asp:Button that has a PostBackUrl to the update page that works great for posting across. I have a asp:LinkButton that has a PostBackUrl to go to the view page but it is not working. Both of these controls are in the GridView. I was wondering why this would be and if there is anything that I can do to get it to work? Is there anyway to tell Atlas to ignore and event in an UpdatePanel for a control?

I found that removing the PostBackUrl property solved a similar sounding issue I had a while back.
