Difference between callback and postback in asp net?
A Postback occurs when the data (the whole page) on the page is posted from the client to the server..ie thedata is posted-back to the server, and thus the page is refreshed (redrawn)...think of it as 'sending the server the whole page (asp.net) full of data'. On the other hand, a callback is also a special kind of postback, but it is just a quick round-trip to the server to get a small set of data (normally), and thus the page is not refreshed, unlike with the postback...think of it as 'calling the server, and receiving some data back' With Asp.Net, the ViewState is not refreshed when a callback is invoked, unlike with a postback.
