Executing Javascript as soon as UpdatePanel trigger is fired

I have found out it is possible to execute javascript after an UpdatePanel has updated it's contents, but is it possible to execute javascript as soon as the trigger is fired?

I could probably hack some messy javascript, but I was wondering if ASP.NET had any 'inbuilt' functionality?

Quote from MSDN - endRequest Event:

The endRequest event is raised after an asynchronous postback is finished and control has been returned to the browser.

In other words you can attach a javascript handler function to the beginning and ending of a partial postback (when the update panel updates).

In the example on the page, you can see that the handler is attached using the PageRequestManager:

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler)

For reference purposes:

beginRequest - Start of the Request.

endRequest - When the request is completed.

I guess there are a few options here you could obviously do something like the following.

<div id="Container" onclick="__doPostBack('UpdatePanel1', '');">

But any of the page life cycle events could be used here is an excellent resource on what and when everything gets called.

UpdatePanel usage implies full page life cycle to be triggered again, so you should be able to catch the document ready, in jQuery terms, like this:

$(function() {
 // Handler for .ready() called.
});

see here: http://api.jquery.com/ready/
