How does AJAX differ from ASP.NET 2.0 Callback? 2

[bitseeker]

How does AJAX differ from ASP.NET 2.0's new CallBack feature? Are they functionally the same thing?

Thanks!

I'm no expert on ASP.NET 2.0, however it seems to callback by invoking server side code from client javascript over XMLHTTP, which is exactly how AJAX works.

The callback feature is Microsoft's first attempt at an AJAX library (it IS AJAX) but it's a bit immature. There are more robust libraries for AJAX and .NET.

Cool. I'll take a look at both in more detail. Thanks for the info!

Asynchronous JavaScript And XML, or its acronym Ajax, is a Web development technique for creating interactive web applications.

As you'll see from that quote, AJAX is simply a methodology that uses JavaScript and XML to transfer data to and from the server/client. Microsoft have developed Client Callbacks classes which allow ASP.NET developers an "easier" way of writing these functions.

Check out the following site for an alternative method of creating these functions:

aj.." is basically a dishonest usurpator marketing word. In its buzz-word launching article, it did not give a fair review of the state of the affair or the matter being core to the scripting/coding construction they want to demonstrate. And now, those less well-informed tend to aj**-this, aj**-that... It would be wise to stay out of that shameful campagne of usurpating other party's technology as their own. Just use some more neutral name at its place.

ca8msm: thanks for input. Knowing more about what can be done with AJAX techniques, and how the mechanics of AJAX works is very useful. It would seem that there is a choice between using an AJAX "product" and MS. At that point, thought, the decision criteria include both technical and commercial factors...much to ponder there. In the meantime, knowing the what and how of AJAX opens the door to designing around it, which is a good thing!

You may also want to keep abreast of the Atlas project which is Microsoft's next crack at AJAX (and it promises to be a BIG deal).

tsuji, I know what you mean! AJAX is pretty overhyped. It's useful for what it does, but people talk about it like the end-all be-all of web programming and it's not.

Thanks for the perspectives!
