Using update panel in AJAX a good practice in asp.net?

Question

Using update panel in AJAX a good practice in asp.net ??? ... or one should code himself for AJAX for each and every control using HTTP-Object ? In which scenarios are the above two strategies used ???

Answer 1

The Update Panel is a good thing in that it allows the developer to code AJAX very simply. It has a lot of overhead, though, and I would not recommend it as a solution in most (if not all) cases.

Look into ASP.Net AJAX for a good way to get started using AJAX. Its fairly simple, robust, and flexible. (It doesn't prevent you from using the update panel either).
