Use Update Progress before redirecting to another page

There are some troubleshooting tips here:http://weblogs.asp.net/leftslipper/archive/2007/02/26/sys-webforms-pagerequestmanagerparsererrorexception-what-it-is-and-how-to-avoid-it.aspx

Server.Transfer typically will cause this problem, but Response.Redirect should be ok (as you found in your test). There is a related post that may help, have a look here:http://forums.asp.net/p/1105985/1692095.aspx

Hope one of these helps you out.
