  Under ASP.NET 4.0,  when using System.Web.Routing  (URL Routing)  with telerik controls on the rendered page.  I am encountering ASP.NET Ajax client-side framework failed to load.
  
  

  <

   

   

  script src="/ThriventPromoRad40/WebResource.axd?d=kuV-9BW9vUE9mrfKFZ3iarEeZ53VRoFdPvU6l_eVkRJWggZVCdkkPTfmCxIghLXyMbupWxfy9hdfoXjjTxbduMDzGQNVIEKoR1dpIpiTxB81&amp;t=634226478236080422" type="text/javascript"></script>

  script src="/ThriventPromoRad40/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&amp;compress=1&amp;_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a1f68db6e-ab92-4c56-8744-13e09bf43565%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%3aen-US%3aaa801ad7-53c4-4f5c-9fd3-11d99e4b92f4%3a16e4e7cd%3aed16cbdc%3a7165f74" type="text/javascript"></script>

   

  <

   

   

  script type="text/javascript">

   

  //<![CDATA[

  if

   

   

  (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');

   

  
   
  If I remove the routing options or if I replace the Telerik controls with generic ASP.NET controls.  (IE: Radbutton with ImageButton).  The page functions correctly. 
  
  Any suggestions?

  I figured it out. 
  
  Add the following to the Global.asax

   

   

  void

   

   

  Application_Start(object sender, EventArgs e)

   

  {

  RegisterRoutes(

   

  RouteTable.Routes);

   

  }

   

   

  void RegisterRoutes(RouteCollection routes)

   

  {

  routes.Add(

   

  new Route("{resource}.axd/{*pathInfo}", new StopRoutingHandler()));
  // Be sure this route is first. 
  routes.MapPageRoute("","{data}","~/WELCOME.aspx");
  //additional routes. 
  
  }

  So it works:
  

   

             static void RegisterRoutes(RouteCollection routes)

          {

              routes.Ignore("{resource}.axd/{*pathInfo}");

              routes.MapPageRoute("Pages", "{DatoEntrada}",

                                  "~/Default.aspx");

       }

         protected void Application_Start(object sender, EventArgs e)

          {

              RegisterRoutes(RouteTable.Routes);

          }

  hello all,
  
  please keep in mind: I had a lot of problems with this; I randomly got blanc pages due to javascript ajax errors ("sys is undefined, telerik is undefined, ajax framework didn't load...)
  
  This only happens with the RadScriptManager, not with the MS one.
  
  lateron i found this post (and similar around the net):
