Question

as you all know update panel send the same response to server as a full post back ( or maybe i am understanding wrong), it is true that it is much better than a full post back.

so is there an alternative to send only response data ? like you have a method that ill return date, i think this is the only thing that should be sent and not the whole control view state that is going to show it ( again maybe i understood it wrong).

i am using Telerik AJAX controls, and they are built upon Microsoft AJAX so there is not much of improvement there.

one approach i like is http://www.coolite.com/ they have AJAX Methods and events, which i think is what i am looking for, but the project is moving slowly and does not have flexibilities for my requirements.

so any input is highly appreciated.

Answer 1

This is why I encourage programmers new to AJAX to learn the basics before adopting a library – when you understand what’s actually happening, this sort of optimization becomes obvious.

so is there an alternative to send only response data? Like, you have a method that will return only a date?

Yes. The most basic way is to just write the date string to the response stream and end the response before anything else is sent – HTTP Handlers (ashx) work great for this. For a more ASP.NET AJAX-friendly technique, check out Web Methods.
