error 405 method not allowed

[Charles]

I have a RadComboBox control (actually, a few of them) in a RadGrid. The RacComboBox controls are configured for load on demand.

They work as expected so long as I have the service code located in a folder within my web app, but as soon as I try to use a separate WCF service application or a separate web application with the ASP.NET Ajax-enabled svc file, I get "error 405 method not allowed" as the response.

Here's the configuration section for my service from the service's application:

<system.serviceModel>

  <bindings>

    <webHttpBinding>

      <binding name="webHttpBindingConfiguration" maxBufferSize="2147483647"

        maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">

        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"

          maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />

      </binding>

    </webHttpBinding>

  </bindings>

  <client>

    <endpoint address="http://localhost:21415/MDMStyleCreateBusinessSvc/MDMBusinessService.svc"

      binding="basicHttpBinding" bindingConfiguration="basicHttpBusinessEndpoint"

      contract="MDMStyleCreateBusinessService.IMDMBusinessService"

      name="basicHttpBusinessEndpoint" />

  </client>

  <services>

    <service name="RadComboLoadingServices"

             behaviorConfiguration="ASPNETAjaxServiceBehaviorConfiguration">

      <endpoint address=""

                behaviorConfiguration="ASPNETAjaxEndpointBehaviorConfiguration"

                binding="webHttpBinding"

                bindingConfiguration="webHttpBindingConfiguration"

                contract="DKS.MDM.StyleCreate.Presentation.RadComboLoadOnDemandService" />

      <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />

    </service>

  </services>

  <behaviors>

    <serviceBehaviors>

      <behavior name="ASPNETAjaxServiceBehaviorConfiguration">

        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>

        <serviceMetadata httpGetEnabled="true" />

      </behavior>

    </serviceBehaviors>

    <endpointBehaviors>

      <behavior name="ASPNETAjaxEndpointBehaviorConfiguration">

        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>

        <enableWebScript />

      </behavior>

    </endpointBehaviors>

  </behaviors>

  <serviceHostingEnvironment aspNetCompatibilityEnabled="true"  multipleSiteBindingsEnabled="true" />

</system.serviceModel>

anybody see anything wrong with the configuration?

In my svc file, I have the following:

[ServiceContract(Namespace = "DKS.MDM.StyleCreate.Presentation")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

and on the contract method, I have:

[OperationContract]
public RadComboBoxData LoadComboItems(RadComboBoxContext context)
{
     ...
}

Thanks,

Charlie

Hi Charles,

The experienced behavior is caused by a XSS restrictions. Here you could find a forum post on the matter.
