With .Net Framework 1.1 I successfully used ComponeneOne WebGrid control. I am now attempting a move to DNN 4.0.3.

When I attempt to load a module containing the C1 webgrid I get an exception:

"Attempted to access a field that is not accessible by the caller"

It fails in Skin.VB at line 466:

objPortalModuleBase = CType(Me.LoadControl("~/" & objModule.ControlSrc), PortalModuleBase)

It is enough to just place the C1WebGrid on the page to cause the error at run time. It just cannot load a module containing this control.  A standard out of the box VS2005 grid causes no trouble.

Has anyone else tried using C1 controls?

Rather than placing the grid on the ascx I tried creating it at run time. 

When I declare it :

Dim C1WebGrid2 As New C1.Web.C1WebGrid.C1WebGrid

I get an exception:

That assembly does not allow partially trusted callers.

How do I get around this?

On attempting to use C1WebGrid without placing the contrl on the ascx at design time I have tried creating the control at run time.  When I do this I get an exception:

A critical error has occurred.
That assembly does not allow partially trusted callers.

This problem seems to have something to do with Trust levels:

Changing trust level to full allows the grid load. I have been in contact with Component One and am hopeful of a resolution.

Thanks Cathal.

Change:
<trust level="Medium" originUrl="http://localhost/.*"/>

to:
<trust level="Full" originUrl="http://localhost/.*"/>
