I have three dropdownlists that filter each other, so, in order to avoid full postbacks i used ur RadAjaxManager. I am getting the following error on some machines:
Sys.WebForms.PageRequestManagerServerErrorException. An error ocurred while processing the request on the server. The Status code returned was:500
Sometimes i get the error.. and it makes it very dificult to debug, because i dont get it even once on my machine and some clients get it..

Unfortunately the error itself does not help much in determining what the source of the issue might be. Can you please post the AJAX-related code as well as the involved controls along with a brief explanation on which action/steps throw the error?

I am having the same issue with two RadComboBoxes and heres the debug message that was caught in the AsynPostBackError event of the scriptmanager.
Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
I am using RadAjaxManager and RadAjaxLoadingPanel for AJAX.
Thanks in Advance,

Can you please use the Visual Studio debugger to see where exactly is this exception?

I wish I could do that but unfortunately the development environment that I am in does not let me debug on the in built Cassini server.This is due to the fact that I have custom authentication setup using CSLA and I will have to remove the entire security model.
The way I debug is write logging code and see the values in the logging tool or throw exceptions and catch it( that's like for every line of code I write, an extra line of logging code to check the values).
Anyways thanks for the reply.

An unknown error occured while processing the requests on the server. the status code returned from the server was: 500
Although from the information you provided I cannot say for certain what might be the exact reason for the issue you are facing, I think that the information from the resources linked below will help you troubleshoot your case to designate the cause of the erratic behavior:

http://www.telerik.com/help/aspnet-ajax/web-resources-troubleshooting.html (the last paragraph of the topic)
If you are not able to determine the reason for the abnormality, please isolate a simple working version of your project ,which works properly with the 2008.3.1125 of RadControls for ASP.NET AJAX and fails with the latest hotfix 2008.3.1314, and send it enclosed to a regular support ticket. We will test it locally and will get back to you with our findings.
