The server-side framework facilitates the developers to develop Ajax functionality, without gaining much knowledge of JavaScript.
This framework supports server controls and components as well as the drag and drop features.
This framework is usually preferred when you required to rapidly ajaxify an asp.net web page. The drawback is that a round trip will take place to the server to
execute a client-side action.
The Client-Side Framework allows you to build web applications with rich user-interactivity as that of a desktop application.
It includes a set of JavaScript libraries, which is not dependent from ASP.NET. The functionalities of this library are enhanced in every release.
