Hi All

I have created custom control (StatePermissionsGrid) based on (StartKit\Library\Security\Permissions\Controls\DesktopModulePermissionsGrid.vb) and placed this source to the folder App_Code.

\App_Code\Custom\Permission\Controls\StatePermissionsGrid.vb
\App_Code\Custom\Permission\CompareStatePermissions.vb
\App_Code\Custom\Permission\StatePermissionCollection.vb
\App_Code\Custom\Permission\StatePermissionController.vb
\App_Code\Custom\Permission\StatePermissionInfo.vb

Code has been compiled without error.

Please advise how to add custom control to the page.

<%@ Register TagPrefix="grid" Namespace="Custom.Security.Permissions.Controls" Assembly="Custom.Security.Permissions.Controls" %>
or
<%@ Register TagPrefix="grid" Namespace="Custom.Security.Permissions.Controls" Assembly="App_Code" %><%@ Register TagPrefix="grid" Namespace="Custom.Security.Permissions.Controls" Assembly="App_Code" %>

<grid:statepermissionsgrid id="dgPermissions" runat="server" />


generate exception:
