When I open an RDL / RDLC file in Visual Studio Design view, It opens as html file.--- Hope this helps. Ananth Ramasamy Meenachi http://www.msarm.com

I found the solution for this issue: Just see the warning message under the warning tab, it seems there is error in the auto generated file. I have faced this issue it several times but now I found why it is behaving so :-)--- Hope this helps. Ananth Ramasamy Meenachi http://www.msarm.com
