Its not a "postback", its a callback, and that is where your javascript
callback function is specified, depending on what AJAX framework you are
running.
For example, a typical JSON structure returned from an "AJAX" call would
actually invoke your javascript function by itself, passing in the JSON data
as an argument.

Regarding the "j" in AJAX, that's actually the ONLY letter in the acronym
that makes any sense:

A - asynchronous: not all Remote Scripting calls are async.
J - javascript: yes - all Remote Scripting involves Javascript.
X - Xml: Just about nobody uses XML anymore with AJAX.

I liked it better when it was just called "Remote Scripting". That was 1998.

see the Sys.WebForms.PageRequestManager, it has an endRequest event you
can attach your javascript to.

Howdy,

From top of my head:
<script type="text/javascript">

var requestManager = Sys.WebForms.PageRequestManager.getInstance();

requestManager.add_initializeRequest(IntializeRequ estHandler);
requestManager.add_endRequest(EndRequestHandler);

function IntializeRequestHandler(sender, args)
{
// this function will be called
// before async request is executed

// do soemthing here
}

function EndRequestHandler(sender, args)
{
// this function will be called
// after async request is completed

// do soemthing here
}

</script>

Hope it helps
