Answer Posted / kiran varma
Postback is something that happens whenever the server
gets a request for this page from the second time onwards
It need not be mandatorily a submit button, probs even a
click which requiers a server side validation is also
results in a postback.
A callback function is a function which you register/ask to
be called later, usually as a result of a particular event
happening.
