Differences are as follow:

Postback: indicates whether the page is being loaded in response to a client postback or it is being loaded first time.

Eample: When you click Button page is first submited to server and then post back to browser, then is time Page.IsPostBack would be true and it would be false if it is normally loaded (eg.it is first time loaded).

CallBack: indicates wether the page request is result of a call back.

Example: Page.IsCallback would be true if a page is loaded by a call from another page.

I believe that this blog post explains the difference very well: http://geekswithblogs.net/AaronLi/archive/2007/04/20/111817.aspx[^]

The link given above by Mika should explain that well.

But let me tell you Google is your or for that matter every programmers' friend!

If you would have tried this - Google Search - difference between postback and callback[^] you would have got 22500 links which somehow discusses the same thing. So next time please, please do a search before you ask. :thumbsup:
