For developers: Override the ResourceAssemblyInfo property

The ContentViewDesignerBase class uses a predefined template for its UI. It is located in the Telerik.Sitefinity.Resources assembly. The ContentViewDesignerBase uses the ResourceAssemblyInfo property to locate its resources. You must override this property to return a type form the Telerik.Sitefinity.Resources assembly. 

To do this, perform the following:

1. Add a reference to the Telerik.Sitefinity.Resources assembly.
   You can find the assembly in folder C:\Program Files (x86)\Telerik\Sitefinity CMS 4.0\Libraries.
2. Override the ResourceAssemblyInfo property to return the type of the Reference class, using the following code sample:
   
   protected override Type ResourcesAssemblyInfo

   {

       get

       {

           return typeof(Telerik.Sitefinity.Resources.Reference);

       }

   }
