RadGrid disappearing on sort after deployment

[Jon]

Good Morning,

I am trying to deploy my VS2010 solution to our internal dev web server (.net 4.0)
so our management team can see the demo i made.

I have included references to
Telerik.Web.Design.dll
Telerik.Web.UI.Skins.dll
TelerikCode.dll

I copy the code out to the dev webserver
Create the IIS directory
Set up the app pool. ect.

The grid shows up with my data in it.
Then i click on the column to sort and the radgrid disappears
This does not happen locally.

What am i missing on my server to make this work?

Thanks, Jon

I found a random post talking about giving the IIS worker process full control the the folder.
it works

why do i need to give it full control??

Hello Jon,

This is not a common problem with our controls, so it should be related to some specific about your scenario. One option is that you are using RadGrid with RadAjax in medium trust, if so take a look at this article and use of of the work arounds:

Also, if you have .NET 3.5 - based Entity Framework binding, try using the following hotfix from Microsoft, as without it such scenario is not supported:

I hope this helps.
