Thanks for the reply Veskoni
That article you pointed me to was helpfull.
For a further question, is there a way I can add the script by referencing the embedded resource inside assembly, instead of copying the scripts files to the application? It would make maintenance and deployment easier. I would like to add the scripts by some line like below
RadScriptManager1.Scripts.Add(New ScriptReference("Core.js", "Telerik.Web.UI")),
except I don't know the naming convention used for the embedded resources.
