Telerik Grid ASP.NET MVC sub grid binding does not work

[C]

Hi.

I’m new at MVC and I have a problem.

The problem is that a sub grid does not show any results.

Here is my view code:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<LogReaderTest.Models.LogModel>" %>

 

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

    Index

</asp:Content>

 

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

 

    <h2>Index</h2>

    <div class="editor-label">

 

        <% Html.BeginForm("Search", "Home", FormMethod.Post); %>

       Start Date<br />

       <%=Html.TextBox("StartDate", ViewData["StartDate"], new { style = "width:80px" })%>

       <br />

       <br />

       End Date<br />

       <%=Html.TextBox("EndDate", ViewData["EndDate"], new { style = "width:80px" })%>

       <br />

       <br />

    <input type="submit" name="submitButton" value="Search" />

    <br />

    <br />

    <%if (Model != null) { %>

    <%= Html.Telerik().Grid(Model.ToDataView)

        .Name("Trades")

        .Columns(columns =>

        {

            columns.Bound("Id").Title("Ticket").Width(80);

            columns.Bound("DateTime").Width(170);

            columns.Bound("Type").Width(230);

            columns.Bound("Message");

        })

        .ClientEvents(events=> events.OnRowDataBound("trades_onRowDataBound"))     

        .DetailView(details => details.ClientTemplate(

            Html.Telerik().Grid(Model.ToDataView)

            .Name("Orders_<#= Id #>")

            .Columns(columns =>

                {

                    columns.Bound("Message");

                })

                .DataBinding(dataBinding => dataBinding.Ajax()

                    .Select("_Orders", "Home", new {

                    ticket = "<#= Id #>"}))

                    .Pageable()

                    .Sortable()

                    .ToHtmlString()

                    ))

        .DataBinding(dataBinding => dataBinding.Server().Select("_Trades", "Home"))

        .Pageable(paging => paging.PageSize(60))

        .Scrollable(scrolling => scrolling.Height(1200))

        .Sortable()

    %>

   <% }

        else if (Model == null)

        { %>

 

 

    <% } %>

    <script type="text/javascript">

 

        function expandFirstRow(grid, row) {

            if (grid.$rows().index(row) == 0) {

                grid.expandRow(row);

            }

        }

 

        function trades_onRowDataBound(e) {

            var grid = $(this).data('tGrid');

            expandFirstRow(grid, e.row);

        }

 

    </script>

 

 

</asp:Content>

The LogModel class is simple class than inherits : IEnumerator, IEnumerable.

Contains ArrayList, getters, setters and IEnumerator, IEnumerable methods

here is my controller:

public class HomeController : Controller
    {


        public ActionResult Index()
        {


            ViewData["StartDate"] = new DateTime(2011, 10, 12).ToString("dd/MM/yyyy");
            ViewData["EndDate"] = new DateTime(2011, 10, 13).ToString("dd/MM/yyyy");

            return View();

        }

        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Search(FormCollection formValues)
        {
            var txbStart = formValues["StartDate"];
            var txbEnd = formValues["EndDate"];
            ViewData["StartDate"] = txbStart;
            ViewData["EndDate"] = txbEnd;

            LogReaderTest.Models.TradesLogModel tlm = new Models.TradesLogModel(new DateTime(2011, 10, 12), new DateTime(2011, 10, 13));

            tlm.SearchByLogin(78);


            return View("Index", tlm);
        }
        public ActionResult Home()
        {
            return View();
        }


        [GridAction]
        public ActionResult _Trades()
        {

            LogReaderTest.Models.TradesLogModel tlm = new Models.TradesLogModel(new DateTime(2011, 10, 12), new DateTime(2011, 10, 13));

            tlm.SearchByLogin(43);

            return View("Index", tlm);
        }

        [GridAction]
        public ActionResult _Orders(int id)
        {
            LogReaderTest.Models.OrdersLogModel olm = new Models.OrdersLogModel(new DateTime(2011, 10, 12), new DateTime(2011, 10, 13));
            olm.SearchLogBy_Mt_Id(id);

            return View("Index", olm);
        }

    }

OrdersLogModel and TradesLogModel are inherid from LogModel

ToDataView method

public DataView ToDataView
       {
           get
           {
               DataTable dt = new DataTable();
               dt.Columns.Add("Id", typeof(int));
               dt.Columns.Add("DateTime", typeof(string));
               dt.Columns.Add("Ms", typeof(int));
               dt.Columns.Add("Type", typeof(string));
               dt.Columns.Add("Message", typeof(string));

               foreach (LogReaderTest.Models.LogLine d in log)
               {
                   dt.Rows.Add(d.Id, d.Datetime.ToString("dd/MM/yyyy HH:mm:ss.fff"), d.Milliseconds, d.Type, d.Message);

               }
               DataView dv = new DataView(dt);

               return dv;
           }
       }
