What is Difference between Callbacks and Postback in ASP.NET?
Answer Posted / dhiraj kumar
Callbacks :- It is a way to get data related to particular
control which is implementing call back. Callback is
nothing but asynchronous postback in which only data
related to the control is came instead of whole page data.
Postback :- It is property of server controls in which
whole page get refreshed. It sends data to server and then
server process the data and after completion of life cycle
process, result is rendered on browser.
Postback is heavyweight methods or execution is slow but
callback is lightweight methods or execution is fast
because here whole page is not getting refreshed or
rendered.
