I just upgraded to SQL 2008 reporting services from 2005. I had a report that I was displaying in an asp.net web page via an iframe. The report had a drill down in it. It worked fine. Now, in SQL 2008, the drill down does not work. I opened the report rdl file in VS2008, edited it and saved it and uploaded it thinking that might help. It still doesn't work. The report has no parameters. When you click the drill down, it appears that the report re-runs and just displays the undrilled down original report.
I also have another report in an iframe that does have a parameter. That also does not work, but I believe it is trying to run the report, but it no longer has a parameter value and I get an error about supplying the required parameter value.
How do I get the drill down to resume working within an iframe?
