Hi Andrey,

Please make sure that the Telerik.Web.UI.WebResource handler is registered correctly:

http://www.telerik.com/help/aspnet-ajax/introduction-web-resources-troubleshooting.html

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="Telerik.ScriptManager.TelerikCdn" value="Disabled"/>
    <add key="Telerik.StyleSheetManager.TelerikCdn" value="Disabled"/>
  </appSettings>
  <system.web>
    <httpRuntime/>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/>
    <pages>
      <controls>
        <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
      </controls>
    </pages>
    <httpHandlers>
      <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>
    </httpHandlers>
    <httpModules/>
  </system.web>
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>
    <handlers>
      <remove name="Telerik_Web_UI_WebResource_axd"/>
      <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode"/>
    </handlers>
  </system.webServer>
</configuration>

Hi, Hristo, Thank you so much. You saved me. It's working for me.

My original one is below:

<add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode,runtimeVersionv2.0" >

After removing the "preCondition", it is working now.

Hi Leo,

We are glad that the Hristo's suggestion is working for you. Just as a quick addition - we would advise that you keep the preCondition, but just removing just the "runtimeVersionv2.0" part of it:

<add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode,runtimeVersionv2.0" >

Thank you, Vessy. 

Yes, forget to mention that I removed "runtimeVersionv2.0" only, and kept the preCondition="integratedMode" Part.

Hi, Vessy

After I removed the "runtimeVersion2.0", the "404 Not Found" is gone, and the popups windows are working; however, the pages don't redirect and display below message:

 

Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a22727c22-244c-4537-8243-3c42cc5b20e2%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2014.1.403.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3aca584452-327f-4858-bf00-fb22c6f6fd75%3a16e4e7cd%3aed16cbdc%3af7645509%3a24ee1bba%3a6a6d718d%3a874f8ea2%3a19620875%3af46195d3%3acda80b3:15 Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Hi Leo,

Usually the experienced error means that the Response was changed during an AJAX request, which often happens when a server error is thrown and there is a redirect for that. You can review this topic which elaborates on this error.

Can you, please, disable the AJAX on the problematic page(s) (or remove temporary the AJAX panels) and see if there is any server- or client-side error thrown when performing the same steps leading to the PageRequestManagerParserErrorException? You can find information on this matter here:
https://www.telerik.com/support/kb/aspnet-ajax/ajaxmanager/details/get-more-descriptive-errors-by-disabling-ajax

Hi, Vessy, Thank you so much for your suggestions although now working in my case after I tried.

Solution:

I removed "runtimeVersionv2.0" for all Telerik element in <handlers> of  <system.webServer> in web.config file. No only "Telerik_Web_UI_WebResource_axd", but also "Telerik_Web_UI_SpellCheckHandler_axd", "Telerik_Web_UI_DialogHandler_aspx" and "Telerik_RadUploadProgressHandler_ashx".

After that, it is working properly.

Thanks again,

Leo
