Excel Exporting -The server closed the connection without se

Question

Hi All,
I am working on JQX Grid in MVC, But when I try exporting as excel from the grid, I am getting error as "The server closed the connection without sending any data" . I know it is not the problem with the JQX. The problem is it happens only if I am exporting large number of data (let us say 8000). I have searched for this , I have found the same problem here http://www.codeproject.com/Questions/413999/The-server-closed-the-connection-without-sending-a, but it does not solve my problem. Help me if you can . Any help is appreciated.

I have tried this also in my web config.
