How can we sort the parameter list in report created using report model in ssrs 2008 r2? Do I need to change some property in Model or elsewhere?

Following is a thread on the same topic. Let us know if helpful. http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/06a22ad8-829b-4b79-9407-f6c0dff58c40Kalman Toth, SQL Server & Business Intelligence Training; SQL 2008 GRAND SLAM

Thanks SQLUSA. I had looked into that thread. I was wondering if this problem has not been solved even till 2008R2. The solution provided needs the custom data processing extenstion. I would except this out of box now. Do you know if it can be done easily without having custom data processing in 2008R2? Thanks ,

The blog is for 2005 Reporting Services....do we still have to go with custom code somebody provided way back for 2005 ??? is it not there still in 2008R2 ??? Thanks,
