Subject: [DOTNET-WINFORMS] MethodAccessPermission

.NETters,

Our application is a WinForms user control that gets hosted
in IE. This user
control contains a DataGridView control among other
controls. Our control
was getting downloaded just fine under IE, that is, until we
added a
DataGridViewLinkColumn column to the datagrid. IE's error
log suggests a
MethodAccessException.

The server the control is downloaded from is in the
"Local Intranet" zone.
It must have all the necessary privileges.

Any suggestions?

Thank you in advance for your help.

Pradeep
