Smart navigation makes web application a real fantastic and pretty look that it feels like it is a window application. Now the questions comes in our mind how its makes web application to window application because one of the drawback of web application is the http architecture means when client send some request to server data is post back and data when come back full redrawing of page it takes really lot of time not only this but also goes top of screen and does not maintain focus on same control on before post back.

But in window application user have ability to change a part or required part to be effected with out change in full page. The smart navigation helps web application to redrawing a full page after post back.

But there is some condition that is always there, the internet explorer must be greater then or equal to version 5. There are many situations where smart navigation do really well enough. We can disable/enable the smart navigation as well. We can use multiple browsers because smart navigation detects it enable on supported browser. There are many more features that smart navigation has:

•Restrict on screen flash.

•Scroll position remains as it is.

•Focus remains as it is.

•History of last page also maintains.

Smart navigation really plays well where lot of post back is to be taken. And another feature that makes it so popular is coder not to code too much for that. This is controlled by the web.config file and a little thing in page directive.
