  We've had a similar issue with HTTP compression. Once we added WebResource.axd to the exclusion list, everything was back to normal. We used Ben Lowery's HTTP compression module.

  Hi, Here is how I have fixed the "Telerik is undefined" js error if that can help anyone here... After having checked the web.config fil I have changed the application pool from DefaultAppPool to Classic .net AppPool and that's it. Without your post I was lost, many thanks

  Perhaps changing the AppPool is not the best solution. When dealing with IIS7 Itegrated mode you need to register HTTP handlers in the system.webServer/handlers section.

  I had the same "telerik undefined" script error, using version 2008.2.723.35. After searching for a very longtime I found a radmultipage wich had the EnableEmbeddedScripts set to false. See for an example the following link: http://www.telerik.com/community/forums/thread/b311D-baettk.aspx Greetings Carol

  Another thing worth checking for if you're getting 404s. If you're running an additional security layer such as SiteMinder or URLScan, that may block access to the .axd files. A number of folks have mentioned the need to put an empty ScriptResource.axd and WebResource.axd file in the root of your app if you use SiteMinder, as that checks whether the files exist. If you're using URLScan, you might need to change the config to put the .axd extension in its white list. Steve

  Also, make sure that if you add a wildcard application map (in Application Configuration section of IIS) for aspnet_isapi.dll, you UNCHECK the "Verify that the file exists" checkbox.  That was what was causing my "Sys is undefined" issue.

  Atanas, I have a RadMenu that displays funny in  the virtual directory. It's vertically aligned whereas  I specified horizontal in development. The menu subitems also display rather than being rolled up. Can you help? I tried looking at "Manually requesting the web resource handle" but I don't have an offending script.
  
  Thanks,

  Im using RadScriptManager but when i Debug the page i've keep getting this error:
  Microsoft ASP.NET AJAX cannot be initialized!
  [Break on this error] if(typeof(Sys) != "undefined"){$addH...t ASP.NET AJAX cannot be initialized!"
  
  RadScriptManager automaticly adds the folowing javascript:
  
  <script type="text/javascript">
  //<![CDATA[ 
      if(typeof(Sys) != "undefined"){$addHandler(window, "load", function(){Sys.Application.initialize();}); } else { throw new Error("Microsoft ASP.NET AJAX cannot be initialized!")}
  //]]>
  

  
  

  
  

  Foolowed yout guide and everything where corerct but stil i get "Microsoft ASP.NET AJAX cannot be initialized!"

  At least this post helped me look in the right place. Everything was put up as it should be, but whatever I did nothing seemed to solv the issue of getting the "'Telerik' is undefined" message.
  
  FINALLY, when diving down into the code I had added this attribute to the RadTreeView control, which seemed to be the root of my problem:

  EnableEmbeddedScripts="False"

  thansk for all of these suggested solution, but actualy none of them worked for me as it is supposed to be, when i applied solution , i got ruined another part of the application, i feel like the telerik aren't capable of interacting with each other, and i did search to the tooth and nail to get somthing suitable to my application , no i got no where, it seems we all share with the same error but totally different secnarios.
  
  
  please i just need to figure out why we are gettign some erros when we use scriptmanager instead of the ScriptManager, they are supposed to do the same functionality.
