Callback is very good approach,when we dont want to postback the whole page to the sever.Here we make the html from server and simply paste that html in our page useing the callback response. For details Have a look

Hi, Callback is used to contact web server(either submitting some information to Web server OR retrieving information from Web Server) in such a way that end user does not experience the processing of request. In simple words when a callback request is made, system serves the request on the web server and present the information requested on the user interface without refreshing the entire web page on the end user's machine. Techinally speaking when a callback request is made then Page_PreRender(Before, On and After) events are not fired and the requested information is handed to user interface, this will prevent the complete rendering of page and only the portion that requested the call back operation/request will be updated. Callback improves the user experience, saves performance and saves the response time. Postback is the normal process that happens when a page contact web server(either submitting some information to Web server OR retrieving information from Web Server) and it refreshes complete page on the web server. In simple words when a postaback occurs complete page is rendered again. Hope this helps, let me know if you need any further information on the same. Thanx, Adil...:))
