Using JQuery UI with Telerik together

I just know that the default configuration of telerik is blocked all JavaScript library. If you want to use another javascript library with telerik, call this method from Application_Start() method in Global.asax

ScriptRegistrar.FrameworkScriptFileNames.Clear();

Your full Application_Start in Global.asax maybe looks like this:

protected void Application_Start()
{
      AreaRegistration.RegisterAllAreas();
      RegisterRoutes(RouteTable.Routes);
      ScriptRegistrar.FrameworkScriptFileNames.Clear();
}
