Please let us know what web application you are using to perform this call back.

 

As the error states,the object you are trying to use ''Rmg.ClientReportTop' ' is not marked as serializable. What exactly is 'Rmg.ClientReportTop' that you are tyring to use.

We are using (ASP.NET 2.0) visual studio .net 2005, and ASP AJAX Ext. 2.0. Does that help?
