Table with a DropDownListFor inside every row in a Partial View .NET

Question

I'm facing a problem with a table inside a partial view, where each row have an dropDownListFor for status list and a button "change status".

But my problem is, if i have 3 row's and change the status when the view model get to controller the selected satus is the status of first row and not the status changed on selected row.

Controller:

public ActionResult AlterarEstadoAfericao(GestaoAfericoesViewModel model)
{
    GestaoAfericoesDbo gestaoAfericoesDbo = new GestaoAfericoesDbo();

    DbUtil dbUtil = new DbUtil();
    string connectionString = dbUtil.generateConnectionString(Connections.Endpoint);

    IntranetDbContext db;
    db = new IntranetDbContext(connectionString);

    var idEstado = db.AF_Estado.Where(a => a.descricao.Equals(model.SelectedEstadoRow)).ToList().First();
    int id_estado = Convert.ToInt32(idEstado.id);

    try
    {
        var dbAF_afericao = db.AF_afericao.Find(model.idSelected);
        dbAF_afericao.id_estado_actual = Convert.ToInt32(id_estado);
        db.SaveChanges();

    }
    catch(SqlException exc)
    {
        Console.WriteLine(exc);
    }

    return RedirectToAction("/GestaoAfericoes");

}

Partial View:

@using (Html.BeginForm("AlterarEstadoAfericao", "Ferramentas", FormMethod.Post))
{

<table id="table" class="table">
    <tr>
        <th>Id</th>
        <th>Descrição</th>
        <th>Início</th>
        <th>Fim</th>
        <th>Origem</th>
        <th>Estado</th>
        <th></th>
        <th></th>
    </tr>
    @if (Model.listGestaoAfericoes != null)
    {
        foreach (var item in Model.listGestaoAfericoes)
        {

            <tr id="@item.id">
                <td id="id">@item.id</td>
                <td>@item.descricao</td>
                <td>@item.data_ini_afericao</td>
                <td>@item.data_fim_afericao</td>
                <td id="origem">@item.origem_afericao</td>
                <td>@item.id_estado_actual</td>

                @Html.HiddenFor(model => model.idSelected, new { @Value = @item.id})

                <td>Estado: @Html.DropDownListFor(model => model.SelectedEstadoRow, (IEnumerable<SelectListItem>)Model.listEstados)</td>
                <td>

                    @Html.ActionLink("Alterar Estado", "AlterarEstadoAfericao", null,
                       new { onclick = "return confirm('Tem a certeza que pretende alterar o estado?');", @class = "btn btn-info" })

                </td>
            </tr>
        }
    }

</table>
}

I tried another way to try a resolution to the problem, but no success.

Partial View:

foreach (var item in Model.listGestaoAfericoes)
{

    <tr id="@item.id">
        <td id="id">@item.id</td>
        <td>@item.descricao</td>
        <td>@item.data_ini_afericao</td>
        <td>@item.data_fim_afericao</td>
        <td id="origem">@item.origem_afericao</td>
        <td>@item.id_estado_actual</td>

        @Html.HiddenFor(model => model.idSelected, new { @Value = @item.id })

        <td>Estado: @Html.DropDownListFor(model => item.SelectedEstadoRow, (IEnumerable<SelectListItem>)Model.listEstados)</td>

        <td>
            @Html.ActionLink("Alterar Estado", "AlterarEstadoAfericao", new { item.id, item.SelectedEstadoRow },
               new { onclick = "return confirm('Tem a certeza que pretende alterar o estado?');", @class = "btn btn-info" })
        </td>
    </tr>
}

Controller:

public ActionResult AlterarEstadoAfericao(Decimal id, string SelectedEstadoRow)
{
    GestaoAfericoesDbo gestaoAfericoesDbo = new GestaoAfericoesDbo();

    DbUtil dbUtil = new DbUtil();
    string connectionString = dbUtil.generateConnectionString(Connections.Endpoint);

    IntranetDbContext db;
    db = new IntranetDbContext(connectionString);

    var idEstado = db.AF_Estado.Where(a => a.descricao.Equals(SelectedEstadoRow)).ToList().First();
    int id_estado = Convert.ToInt32(idEstado.id);

    try
    {
        var dbAF_afericao = db.AF_afericao.Find(id);
        dbAF_afericao.id_estado_actual = Convert.ToInt32(id_estado);
        db.SaveChanges();

    }
    catch (SqlException exc)
    {
        Console.WriteLine(exc);
    }

    return RedirectToAction("/GestaoAfericoes");

}

The id came to controller with correct value, but SelectedEstadoRow have a null value on the controller.
