I am deploying a site on a hosted server that uses RadControls for ASPNET AJAX Q3 2008. Everything runs fine locally. The site is throwing the error below after the RadGrid runs through OnNeedDataSource.

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Any help would be appreciated.

Vlad,

Here is what the server administrator had to say about the trust level.

All websites under .NET 2.0/3.0/3.5 run under a custom trust level, derived from the Medium trust level. In addition to all allowed through Medium trust, we allow OLEDB and ODBC functionality. If you’re using the latest version of the control from Telerik, it should be working.

That being said, I did some research and have tweaked some permissions on the site, granting NETWORK SERVICE access to the assembly. I’m not sure which page was giving you trouble, but please try again and let me know whether or not it’s working.

Update:
After a bit of testing, I have narrowed it down to 2 things. If I remove the AllowPaging property from the grid, it works fine. I also receive the same error if I try to sort by clicking on one of the colums. Grid markup below.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"
Width="500px"
OnNeedDataSource="RadGrid1_NeedDataSource"
PageSize="25"
AllowSorting="True" AllowPaging="true" GridLines="None">
<MasterTableView DataKeyNames="OrderId">
   <Columns>
     <telerik:GridTemplateColumn>
     <ItemTemplate>
       <asp:LinkButton ID="lbtnEdit" runat="server"></asp:LinkButton>
     </ItemTemplate>
     </telerik:GridTemplateColumn>
     <telerik:GridBoundColumn DataField="ShowName" HeaderText="Show" SortExpression="ShowName"></telerik:GridBoundColumn>
     <telerik:GridBoundColumn DataField="Amount" HeaderText="Amount" SortExpression="Amount"></telerik:GridBoundColumn>
     <telerik:GridBoundColumn DataField="Status" HeaderText="Status" SortExpression="Status"></telerik:GridBoundColumn>
   </Columns>
</MasterTableView>
</telerik:RadGrid>

Thanks,
Doug
