RadControls for ASP.NET AJAX are built on top of the MS AJAX Framework and that is why their client-side API follows the conventions of the AJAX Framework. As these are server controls and they implement the IScriptControl interface, you should to use the $find()
method to access them. Once you have access to the component client-side object, you can use its public client-side and server-side properties to manipulate it.
It's hard to change the current APIs as this would lead to introducing breaking changes in the controls. However when making new components or new methods and properties, we will do our best to make them simpler.
Hope this helps.
All the best,
the Telerik team
