StateServer sessionState and JQGrid

Question

My users are constantly logged off the web app, so I am trying to use <sessionState mode="StateServer" cookieless="false" timeout="480" /> but I get a server error 500 because JQGrid cannot be serialized. Any ideas?

Answer 1

I stopped using

Session["MyGridState"] = model.MyGrid.GetState();

Answer 2

Change Webconfig sessionState to InProc and change IIS WorkerProcess to 1

"<system.web>    
<sessionState mode="InProc" timeout="25"></sessionState>
