Which Ajax Library for ASP.Net

Trying to decide

[Red_Eye]

I am looking at creating a web applicaton (I am using visual studio 2005). Normally I would do this in the normaly way however I feel that as it would benfit from ajax to make it feel a bit more like a desktop app.

I have been looking at a few examples for Ajax

1. Anthem.Net
2. MS Atlas
3. Ajax.Net.

Does any one have any experianace of any of these lib's and if so which would they recommend. I am looking for the simplest to intergrate / use.

Thanks in advance

The libs in question have some differences in how they are designed fundamentally, which could affect how you design your website project.

Ms Atlas uses a methodology to post everything back to the page to trigger all the events, and then returns a JavaScript back to make the changes. Depending on the site the extra post backs which include the entire viewstate which can be rather large, can eat up a lot of extra bandwidth.

Ajax.Net is more of a webservice approach, where you define the function and it will convert the result of that function into a JavaScript/json stream to be used by the client’s browser. And this does not send the entire viewstate the last time I evaluated it.

My personal preference is to use more of an Ajax.Net approach and define very specific function, that effect the data being displayed and items currently visible, without the overhead of sending the entire viewstate and requiring a complete page reload to process the request.

I have just been playing with Atlas for the moment and have found it very simple to achieve what I want. I will try the other 2 and see how it goes but I might stick with Atlas
