Hi Hari....

Thanks for asking question. I would recommend you to read the entire ASP.NET Ajax rather than learning control by control. It may take few hours but it worth spending few hours to get enough idea about ASP.NET AJAX. Here is the tutorials on this website http://www.dotnetfunda.com/tutorials/ajax/updatepanel.aspx that's why I am giving link here.c

Hope this helps.

Thanks

1.ASP.NET UpdatePanel controls enable you to build rich, client-centric Web applications. By using UpdatePanel controls, you can refresh selected parts of the page instead of refreshing the whole page with a postback. This is referred to as performing a partial-page update.

2.When you use an UpdatePanel control, the page behavior is browser independent and can potentially reduce the amount of data that is transferred between client and server.
