Hello Srinivasa Rao Ranga,

The reason for this postback is because the navigation triggered on nodeClick event. The way a masterPage works is fairly different that one could expect (including me in this number):
- Instead updating only the content place holder, navigating to different content pages, makes a full navigate (merge between master and requested page) like opening a new page.

In order to achieve the smooth update that you want here you probably will not use a masterpage. You can use a regular page in which you can update some placeHolder (again through updatePanel or better through our RadAjaxManager, using server-side code to change the content in this placeHolder).

Also there is another solution that comes in mind - you can use an iFrame, but then the placeholder will be full page.

Hope this is helpful for you!
