Unable to add a ReportViewer to a web page

Hi All

I have used ReportViewer in winforms projects in the past with no problems at all.

I would now like to use it in a web application; however, when I try to drag and drop the control onto the web page in design mode I get a pop up saying "Access is denied".

There are lots of threads out there where people have experienced this but none seem to have a solution.

I am using visual studio 2005 (it's an old project that we don't want to convert at this stage) and .NET framework 2.

NB the same thing happens if I try to drag and drop the CrystalReport's viewer also.

All other controls drag and drop without any issues.

Any help would be gratefully appreciated.

Thanks
Dave
