In Gmail once you received a new email it will update your inbox page with the new email without you reloading the page. How is Gmail doing this? How does Gmail knows I have a new email? From what I know AJAX only works if there's an action from a user, is this correct?

Please provide a sample code / a link to a tutorial on how I could do this.

different method if you're trying to do this using IMAP, POP or HTTP

No, you can do an ajax call using a timer, at page load and so on

I should have been more clear, I'm not doing this to access emails. I just want the functionality of Gmail where it knows there is new data for the inbox. In my case instead of emails, my data would come from the database. I need to update the page as soon as there is new data saved on the database.

Isn't this a resource heavy solution for the user? Is this how Gmail is doing it? A non stop timer?

My response was very terse I hit submit before explaining it. So much of the GMAIL functionallity is exposed to developers through Google API where you can get into the code of nearly everything Google has. If you follow my link and start searching and exploring in there you will find everything you need.

The term is << pulling >>, check this (HTTP Pull) : http://www.infoq.com/news/2007/07/pushvspull
At the opposite, << pushing >> same page (Reverse AJAX)

you have good info on the page.
setInterval on the client : http://www.w3schools.com/jsref/met_win_setinterval.asp
comet and ajax push on the server : http://www.ape-project.org/ and http://en.wikipedia.org/wiki/Comet_(programming)

Hi, You have to use the ajax control like update panel, and set its target control to refresh button. It is working like gmail inbox. Try this otherwise I will give you a video tutorials for ajax. ok
