[Solved] GridState == null on WCF operation call

[John]

I am using MvcTurbine/Ninject/db4o/Telerik MVC 2010.1.309 in a simple web site prototype.
I am now stuck debugging a WCF service, the 'Select' operation is being passed null for the GridState.
All the Dependency Injection works, the model correctly returns GetAll() in nUnit tests.
What would cause a null to be passed to GridState?
What am I missing?

thanks in advance...

WCF interface:

namespace Necropolis.Habitat.Services
{
   using System.ServiceModel;

   using Telerik.Web.Mvc;

   [ServiceContract]
   public interface IISO
   {
      [OperationContract]
      GridModel Select(GridState _state);

   }
}

WCF service, markup included:

namespace Necropolis.Habitat.Services
{
   using System.Linq;
   using System.ServiceModel;
   using System.ServiceModel.Activation;

   using Ninject;
   using Telerik.Web.Mvc;
   using Telerik.Web.Mvc.Extensions;

   /*
    <%@ ServiceHost Language="C#"
                   Debug="true"
                   Service="Necropolis.Habitat.Services.ISO"
                   CodeBehind="ISO.svc.cs"
                   Factory="Necropolis.Habitat.Infrastructure.DIServiceHostFactory" %>
    */

   [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
   [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
   public class ISO : IISO
   {
      private Necropolis.ISO.Model.Contracts.Models.IISO_639_3_LanguageCode model_;

      [Inject]
      public ISO(Necropolis.ISO.Model.Contracts.Models.IISO_639_3_LanguageCode _model)
      {
         model_ = _model;
      }

      public GridModel Select(GridState _state)
      {
    // PROBLEM:
    //
    // _state == null

         return (model_.GetAll().AsQueryable().ToGridModel(_state));
      }
   }
}

This is the view:

<%@ Page Language="C#"
            MasterPageFile="~/Views/Shared/Site.Master"
            Inherits="System.Web.Mvc.ViewPage<IEnumerable<Necropolis.ISO.Model.Contracts.IISO_639_3_LanguageCode.View>>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<%
    GridPagerStyles pagerStyles = GridPagerStyles.NextPreviousAndNumeric
                                    | GridPagerStyles.PageInput
                                    | GridPagerStyles.NextPrevious
                                    | GridPagerStyles.Numeric;

    Html.Telerik().Grid<Necropolis.ISO.Model.Contracts.IISO_639_3_LanguageCode.View>(Model)
        .Name("Grid")
        .DataKeys(keys =>
        {
            keys.Add(c => c.GUID);
        })
        .Columns(columns =>
        {
            columns.Bound(o => o.Code).Width(80);
            columns.Bound(o => o.RefName);
        })
        .DataBinding(dataBinding => dataBinding
            .WebService()
                .Select("~/Services/ISO.svc/Select")
        )
        .Groupable()
        .Sortable()
        .Pageable(paging => paging.Style(pagerStyles).PageSize(30))
        .Filterable()
        .Scrollable()
        .Footer(true)
        .Render()
        ;
%>
</asp:Content>

Hello John,

The name of the web service method must be "state" not "_state". You can refer to our online example for more info.
