Control add-ins for the Microsoft Dynamics NAV are built with the Microsoft .NET Framework–based assemblies that you install on computers that are running the Microsoft Dynamics NAV Windows client.
To include a control add-in on a Role Center, you apply the control add-in on a page that is assigned to a part of the Role Center. Control add-ins are not supported by the Microsoft Dynamics NAV Web client or Microsoft Dynamics NAV Portal Framework for Microsoft SharePoint 2010
