My model have a property list and this property has another inside.
I made changes to this properties list before make submit but many properties hasn't values, they lost.

Main Model with lists

public class PedidosViewModel : BaseFormViewModel<long>

{

//Main properties here



public List<PedidosDetalleViewModel> PedidosDetalle { get; set; }

}



public class PedidosDetalleViewModel

{

    public long Id { get; set; }

    public long IdPedido { get; set; }

    public long IdEstiloCombinacion { get; set; }

    public string Combinacion { get; set; }

    public string Descripcion { get; set; }

    [Required]

    [RegularExpression(@"^[0-9]*$", ErrorMessage = "La Cantidad debe ser numérico entero")]

    public int CantidadPares { get; set; } = 0;

    public decimal Precio { get; set; }

    public decimal PrecioMoneda { get; set; }

    public decimal Importe { get; set; }

    public decimal ImporteMoneda { get; set; }

    public int Estatus { get; set; }

    public string EstatusStr { get; set; }

    public List<PedidosDetalleCorridaViewModel> PedidosDetalleCorrida { get; set; }

}



public class PedidosDetalleCorridaViewModel

{

    public long Id { get; set; }

    public long IdPedidoDetalle { get; set; }

    [StringLength(20)]

    public string Punto { get; set; }

    [StringLength(20)]

    public string Valor { get; set; }

    [RegularExpression(@"^[0-9]*$", ErrorMessage = "La Cantidad debe ser numérico entero")]

    public int CantidadPares { get; set; } = 0;

}

In the partial view with the list details i have:

@{ int rowNum = 0; }

    @for (int j = 0; j < Model.PedidosDetalle.Count(); j++)

    {

        <tr>

            <td>

                @(rowNum += 1)

                @Html.HiddenFor(m => m.PedidosDetalle[j].Id)

                @Html.HiddenFor(m => m.PedidosDetalle[j].IdEstiloCombinacion)

                @Html.HiddenFor(m => m.PedidosDetalle[j].IdPedido)

                @Html.HiddenFor(m => m.PedidosDetalle[j].Combinacion)

                @Html.HiddenFor(m => m.PedidosDetalle[j].Descripcion)

                @Html.HiddenFor(m => m.PedidosDetalle[j].Precio)

                @Html.HiddenFor(m => m.PedidosDetalle[j].PrecioMoneda)

                @Html.HiddenFor(m => m.PedidosDetalle[j].Importe)

                @Html.HiddenFor(m => m.PedidosDetalle[j].ImporteMoneda)

                @Html.HiddenFor(m => m.PedidosDetalle[j].Estatus)

                @Html.HiddenFor(m => m.PedidosDetalle[j].EstatusStr)

                @Html.HiddenFor(m => m.PedidosDetalle[j].CantidadPares)

                @for (int i = 0; i < Model.PedidosDetalle[j].PedidosDetalleCorrida.Count(); i++)

                {

                    @Html.HiddenFor(m => m.PedidosDetalle[j].PedidosDetalleCorrida[i].Id)

                    @Html.HiddenFor(m => m.PedidosDetalle[j].PedidosDetalleCorrida[i].IdPedidoDetalle)

                    @Html.HiddenFor(m => m.PedidosDetalle[j].PedidosDetalleCorrida[i].Punto)

                    @Html.HiddenFor(m => m.PedidosDetalle[j].PedidosDetalleCorrida[i].Valor)

                    @Html.HiddenFor(m => m.PedidosDetalle[j].PedidosDetalleCorrida[i].CantidadPares)

                }

            </td>

            <td>@Html.DisplayFor(m => m.PedidosDetalle[j].Combinacion)</td>

            <td>@Html.DisplayFor(m => m.PedidosDetalle[j].Descripcion)</td>

            <td>@Html.DisplayFor(m => m.PedidosDetalle[j].CantidadPares)</td>

            <td>@Html.DisplayFor(m => m.PedidosDetalle[j].PrecioMoneda)</td>

            <td>@Html.DisplayFor(m => m.PedidosDetalle[j].ImporteMoneda)</td>

            <td>@Html.DisplayFor(m => m.PedidosDetalle[j].EstatusStr)</td>

            <td>

                <a class="btn btn-md btn-primary" onclick="CargarDetalle(@Model.PedidosDetalle[j].Id)" href="javascript:void(0);"><i class="fa fa-pencil"></i> Editar</a>

            </td>

            <td>

                <a onclick="EliminarPedidoDetalle(@Model.PedidosDetalle[j].Id)" href="javascript:void(0);"><i class="glyphicon glyphicon-remove-sign icons-app icons-md icons-app-danger"></i></a>

            </td>

        </tr>

    }

as you can see many hidden controls just for keep the values when i postback, but properties like Id, Importe, Estatus lost their values. I am thinking to use session (because .net MVC don't have viewstates) for save temporary my detail list with all values and edit values list if i need just before save changes.
I use javascript for load the partial view with an ajax call for pass all the form serialized every time i add new record in the list.
There is a solution with MVC, Ajax and mainting the values in my main model.

This is the screen:
