Retrieve Ienumerable values from View

Question

I have a table/model called Itemtabelapreco:

public class ItemTabelaPreco
{
    public string Nome { get; set; }
    public decimal ValorUnitario { get; set; }
    public int QtdPacote { get; set; }
    public decimal ValorPacote { get; set; }
    public int TabelaPrecoId { get; set; }
}

And another call Tabelapreco:

public class TabelaPreco
{
    public int Id { get; set; }
    public string Nome { get; set; }
    public decimal Valor { get; set; }
    public IEnumerable<ItemTabelaPreco> ListaItemTabelaPreco { get; set; }
}

In the table view I load the list:

@model Aplicativo.Models.TabelaPreco

@foreach (var list in Model.ListaItemTabelaPreco)
{
    @Html.Raw(list.Nome)
    @Html.TextBoxFor(Model => list.ValorUnitario)
    @Html.TextBoxFor(Model => list.QtdPacote)
    @Html.TextBoxFor(Model => list.ValorPacote)
}

The problem I have is time to recover the values of this view list in the edition of the Table in the controller after the post, I have tried several ways and always comes the empty list, the other fields that are not from this list, comes the values correctly:

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(TabelaPreco tabelaPrecoModel)
{
    tabelaPrecoModel.ListaItemTabelaPreco VEM SEMPRE NULL.
}

If anyone can help, I’d appreciate it.

Answer 1

Try changing the foeach by a traditional for

  @for (int i = 0; i != Model.ListaItemTabelaPreco.Count(); ++i)
 {
@Html.Raw(list.Nome)
@Html.TextBoxFor(m => Model.ListaItemTabelaPreco[i].ValorUnitario)
@Html.TextBoxFor(m=> Model.ListaItemTabelaPreco[i].QtdPacote)
@Html.TextBoxFor(m => Model.ListaItemTabelaPreco[i].ValorPacote)
 }
