In my IIS 5 Test Environment, I have a ModalPopup come up and show some options that are populated from a DB. When I hit the "Save" button on the Panel, it hits my click event handler and updates the DB, then repopulates the page with data without a postback.

In IIS 6, on my production server, it posts back the entire page on that button click. Why is it doing this in production, but not on my machine's environment?

Where are you testing this page? What browser in what environment?

This could be because you are trying to test this from I.E. on the server itself. The default installation of I.E. is pretty locked down on windows server 2003. It could simply be because I.E. isn't set to support the complex javascript needed by ajax.

It works on my local machine environment in Firefox, IE 6, IE 7. So I don't think it's limited by IE. I've heard it's possibly an installation on the server that is out of date, but would an out of date AJAX extension cause the Popup to still come up, but the UpdateProgress and the UpdatePanel to not work correctly?

Can you explain more about the application configuration in general?

Is this a compiled web application project or a web site? Does it have a web config?

Can you view the source HTML for the version that isn't working and see if all the AJAX parts are getting emitted the same way as for the working version?

Is this site somewhere public where we could look at it to diagnose the problem?
