We have an ASP.NET forms app which makes use of the Telerik RadGrid. One particular page has some code that allows the user's search criteria to be remembered (not sure if this relevant).

Quite often when adding updated or new pages to the same folder the page with the RadGrid starts crashing even though this page hasn't been updated itself. It seems more likely to crash for people who were using the page when the other content changed as it doesn't normally affect everybody. The problem can normally be cleared up by recycling the application pool or resetting IIS (Which isn't always possible to do quickly)

We have recently moved to a new web server (Windows 2012 / IIS8). We had the problem on the old server too - I was hoping the server move would help but it hasnt. Can anyone offer any advice?

Part of the error is pasted below

A]GridSettingsCollection cannot be cast to [B]GridSettingsCollection. Type A originates from 'App_Code.tjhpcefj,

Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET

\Framework64\v4.0.30319\Temporary ASP.NET Files\root\4d0bd47d\b6b2e877\App_Code.tjhpcefj.dll'. Type B originates from

\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\4d0bd47d\b6b2e877\App_Code.oxtbck2r.dll'.

Source Error:

Line 370: Public Shared Function LoadFromSerializedData(ByVal data As String) As GridSettingsCollection

Hello Graeme,

Based on the presented error it is a bit difficult to directly isolate the root cause of the issue you are facing.
Can I kindly ask you to post the full stack trace of the presented error so that we can revise it locally and advise you further?
It will also be very helpful if you post your full page markup as well as related code behind so that we can revise your code and do our best to isolate the problem.
