ASP.NET MVC 4 DropDownList SelectedValue doesn't work

I'm trying to use the DropDownList helper to build a select list with a selectedvalue in an ASP.NET MVC 4 appliction, but when the dropdownlist is generated, it doesn't have any selected value, even if the SelectList given as source have the SelectedValue set. Here's the code: My model: ``` using System; using System.Collections.Generic; using System.Linq; using System.ComponentModel.DataAnnotations; namespace MvcApplication3.Models { public class Conta { public long ContaId { get; set; } public string Nome { get; set; } public DateTime DataInicial { get; set; } public decimal SaldoInicial { get; set; } public string Owner; public override bool Equals(object obj) { if (obj == null) return false; if (obj.GetType() != typeof(Conta)) return false; Conta conta = (Conta)obj; if ((this.ContaId == conta.ContaId) && (this.Owner.Equals(conta.Owner)) && (this.Nome.Equals(conta.Nome))) return true; return false; } public override int GetHashCode() { int hash = 13; hash = (hash * 7) + ContaId.GetHashCode(); return hash; } } } ``` My Controller: ``` using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using MvcApplication3.Models; namespace MvcApplication3.Controllers { public class HomeController : Controller { public ActionResult View1() { Conta selecionada = new Conta() { ContaId = 3, Nome = "Ourocard VISA", Owner = "teste" }; SelectList selectList = new SelectList(Contas(), "ContaId", "Nome", selecionada); ViewBag.ListaContas = selectList; return View(); } IEnumerable<Conta> Contas() { yield return new Conta() { ContaId = 1, Nome = "Banco do Brasil", Owner = "teste" }; yield return new Conta() { ContaId = 2, Nome = "Caixa Econômica", Owner = "teste" }; yield return new Conta() { ContaId = 3, Nome = "Ourocard VISA", Owner = "teste" }; yield return new Conta() { ContaId = 4, Nome = "American Express", Owner = "teste" }; } } } ``` My View: ``` <h2>View1</h2> @Html.DropDownList("teste", ViewBag.ListaContas as SelectList) ``` The dropdown is built with the four options that the Contas() method created, but none of them is selected. What could it be?
