error with url mapping

[Jonathan Hunter]

In a website I'm developing, I'm mapping URL paths to specific files with query strings. This was working great with the non-Ajax controls (both Q1 and Q2) but when I put in the AJAX Manager, or Panel, it breaks. Each time a page starts the request, an error will pop up saying the following:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 404

If I replace <telerik:RadAjaxPanel></telerik:RadAjaxPanel> with <radA:RadAjaxPanel></radA:RadAjaxPanel> everything goes back to working as expected.

Is there a way to get the AJAX version to work with URL mapping like the non-AJAX version? I can use the standard <radA:RadAjaxPanel> but I'd like to swap it out if at all possible.

Thanks!

Hello Jonathan,

The new AJAX controls as well the other controls from the ASP.NET AJAX suite are built on top of the MS AJAX framework. Have you tried replacing the panel with the standard UpdatePanel? Do you get the error there as well?

Hello Konstantin,

I switched out a non-AJAX (Prometheus) RadAjaxPanel with the AJAX Extensions Update Panel (I assume this is what you meant) and it started tossing that same error again.

This kinda baffles me. Why would it work with the standard RadAjaxPanel and not the AJAX/Prometheus version? Is it just based on different code?

Hello Jonathan,

This is e exactly what I meant. The new RadAjax is built on top of MS AJAX and generally those scenarios which fail with MS UpdatePanels for example will fail with the new RadAjaxPanel/RadAjaxManager. The "Classic" RadAjax framework is entirely different though and we support some other scenarios there. While on this topic, you may find the following articles helpful:

Hey Konstantin,

This is what I was afraid of. I appreciate your help tremendously. Thanks!

Just wanted to update this post as i have found a fix for this issue and thought it might be useful for anyone hitting the same issue:

Post this code on your front-end code...

<script language="JavaScript" type="text/javascript">
function EndRequestHandler() { theForm.action = document.location.href; theForm._initialAction
= theForm.action; } if( typeof(Sys) != "undefined" ) { EndRequestHandler(); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}</script>

Hope this helps

Thanks a lot for this info. Had the same issue and the above Javascript solved my problem. Strange that this is not mentioned anywhere in the documentation. Anyone serious about E-Business use URL rewriting.

I am not getting an error, my problem is like this:
I have an asp.net 3.5 website, I actually have more than one and my webrewrite works on all the others, but not this one.  The only difference I can think of is I am using Ajax toolkit on this one. 

If I manually type in the new url,,,that WORKS!, BUT  if I hit it from a link that is directing me to the old link, it doesn't rewrite it!  Any help for me??  If you want you could also email me at [e-mail].  Thanks.
