Indeed, the method you have found will do the trick but I strongly recommend to use the public set_enabled method - it has some additonal custom logic in it that will handle all the scenarios. Furthermore it is always recommended not to use private methods but only public ones for reliability because the private ones are considered for internal use and could be modified, refactored, etc in a manner that might cause troubles in future upgrades if they are used while we always keep the public ones backwards compatible. I want also to inform you that we are currently working on improving the RadRating documentation and adding javascript intellisense for all RadControls in order to save our clients time and efforts in such cases.
