WCF error with gridbindingservice.svc

[Mark]

When I try to use the AJAX SharePoint Rad Data grid web part, it returns no data. The designer also doesn't allow me to select columns - it comes back in the event log with an error about the WCF service Telerik installs:-

Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service.

How can I make this go away, it is a standard team site, I don't want to enable anonymous authentication.

I have discovered what this is. Our site is under a managed path under a URL like this:-

http://somesite/app1/default.aspx

This is a site collection root under managed path app1. We do not have any site collection under the root / managed path, all the sites exist under /sites or othere managed paths.

I think the web part is trying to communicate with http://somesite/_vti_bin/Telerik... when it should communicate through the current site collection root NOT the web application root. I temporarily created a dummy site under / and everything started to work again.

Is there anyway around this? Makes the controls unusable for us.

Hi Mark,

Does your problem appear with the new version of the telerik controls for sharepoint?

Cool, I also have the same issue of managed path as Mark said. I am getting
ErrorText=Security settings for this service require Anonymous Authentication but it is not enabled for the IIS application that hosts this service.

Mark- how did you create empty site and on which path can you please elaborate?

Hello amit,

The SPRadGrid web services should work all right without anonymous authentication. Once again, have you downloaded the latest installer for the acceleration kit?

Hi Tsvetoslav,

It's working fine with new version. Thanks!

Hi, am seeing the same problem. I am using the 2012 Q1 version of the SharePoint Acceleration Kit, is this the most recent version? If so please advise.
Thanks

Hi Mark,

Try downloading the ajax installer for the SharePoint 2010 telerik controls - it contains a more recent version of the TelerikSPRadGrid web part. It should be found once you click download on the ajax producs panel.

Hi,

I had the same problem, even after updating to the latest version of the controls (2012.2.912.35).
The problem occures because SharePoint works with authentication and the "Anonymous Authentication" is disabled.
The gridbindingservice.svc has it's separte config file, which by default is not configured to take authentication into account and thus fails.
I managed to get the service to work after updating the web.config on the following location:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Telerik.Ajax.SharePoint\web.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpEndpointBinding">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Ntlm" />
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
    <behaviors>
      <endpointBehaviors>
        <behavior name="webScriptBehavior">
          <enableWebScript/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <services>
      <service name="Telerik.Ajax.SharePoint.GridBindingService">
        <endpoint address="/javascript" behaviorConfiguration="webScriptBehavior"
          binding="webHttpBinding" bindingConfiguration="webHttpEndpointBinding"
          contract="Telerik.Ajax.SharePoint.IGridBindingService" />
      </service>
      <service name="Telerik.Ajax.SharePoint.SchedulerBindingService">
        <endpoint address="" behaviorConfiguration="webScriptBehavior"
          binding="webHttpBinding" bindingConfiguration="webHttpEndpointBinding"
          contract="Telerik.Ajax.SharePoint.ISchedulerBindingService" />
      </service>
    </services>
  </system.serviceModel>
</configuration>

A bindingconfiguration is defined now on the endpoint which makes the endpoint use the security.
This got the communication with the service working. This is one step closer, but although the communication is working now, I don't get any data in the grid yet. So I continue my search...

I hope this configuration helps out some people who had the same problem.

Hello Hans,

Could you check with FireBug (or another tool) what the call to the service is returning?
