  asp.net ajax client-side framework failed to load

  Nov 04, 2009 06:56 PM|LINK

  If you are having problems with the "asp.net ajax client-side framework failed to load" error and you are using forms authentication you need to allow users access to WebResource.axd and ScriptResource.axd. If you are using Telerik's controls you need to allow users access to Telerik.Web.UI.WebResource.axd.

  <authentication mode="Forms">
      <forms loginUrl="Logon.aspx" name="authticket" timeout="20" path="/" />
  </authentication>
  <authorization>
    <deny users="?" />
  </authorization>

    <location path="WebResource.axd">
      <system.web>
        <authorization>
          <allow users="*" />
        </authorization>
      </system.web>
    </location>
    <location path="ScriptResource.axd">
      <system.web>
        <authorization>
          <allow users="*" />
        </authorization>
      </system.web>
    </location>
    <location path="Telerik.Web.UI.WebResource.axd">
      <system.web>
        <authorization>
          <allow users="*" />
        </authorization>
      </system.web>
    </location>  

  I hope that information prevents hair loss as well as saves somebody some time!

  Ajax error Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The system cannot find the file specified.

  For me it was working on server 2003 with IIS 6 perfectly but not in server 2008 with IIS7. Then what I did was I compared web.config with web.cofig of example code in Ajax control tool kit.

  Then only different was <system.webserver></system.webserver> block. when I copied that into my config,then issue was gone.
