[Solved] JSON Error When SQL StateServer

[Jose Miguel]

Hello all

i have a very weird problem, i have a MVC Telerik Grid in my application, this grid is configured for custom binding, it supports pagination and sorting, the grid was working fine.

Today i changed my StateServer from InProc, to SQL Session State Server, and then the grid started showing me the following error:
"Error! The requested URL did not return JSON"

I See that i fill the information same as when it was InProc, but if i use fiddler to see the request/response, i see that the response changes to empty when switching into SQL State Server,

This is how i'm returning the data:

return View(new GridModel { Data = matchedInfo, Total = total }); 

and the method has the following attribute:

[GridAction(EnableCustomBinding = true)] 

As i'm saying in order for me to reproduce this, i only change the configuration in IIS to go to SQL State Server.

Thanks in advance.
