MVC下拉列表复杂的父模型

我想我在这里错过了一个简单的原则，有人会很快指出来。我实际上有一个Person对象，它包含一些基本属性，然后是几个Lists<>用于电话和地址。电话和地址各有一个类型(家庭/工作/等)。地址也有一个州和县。

当我执行管理操作时，我正在为CountyId, StateProvinceID等设置ViewBag，但是当我有第二个地址或电话时，这些下拉框似乎没有正确的选择值。

我敢肯定这是我做错了什么可悲的基本…

解决…

我知道我缺少一些基本的东西，答案是简单地为Address和Phone对象创建自定义视图模型。这些新的视图模型可以包含这些选择列表中的每个列表…

模型示例

public CustomerModel()
    {
        IsActive = true;
        if (Phones == null)
        {
            Phones = new List<Phone>();
        }
        if (Addresses == null)
        {
            Addresses = new List<Address>();
        }
    }
    public Guid Id { get; set; }
    public Guid OrganizationId { get; set; }
    [Required]
    public String FirstName { get; set; }
    public String MiddleName { get; set; }
    [Required]
    public String LastName { get; set; }
    [RegularExpression(".+''@.+''..+", ErrorMessage = "Please enter a valid email address.")]
    public String EmailAddress { get; set; }
    [DataType(DataType.Date)]
    public DateTime? DateOfBirth { get; set; }
    public List<Phone> Phones { get; set; }
    public List<Address> Addresses { get; set; }
}

父视图示例

<tbody id="tblAddressRows">
    @foreach (var address in Model.Addresses)
    {
        Html.RenderPartial("_AddressRow", address);
    }
</tbody>

局部视图示例

<td>
    @Html.HiddenFor(a => a.Id)
    @Html.DropDownList("AddressTypeId", ViewData["AddressTypeId"] as SelectList)
</td>
<td class="AddressLines">
    @Html.EditorFor(a => a.AddressLine1)
    @Html.EditorFor(a => a.AddressLine2)
</td>
<td>
    @Html.EditorFor(a => a.City)
</td>
<td>
    @Html.DropDownListFor(m => m.StateProvinceId,  ViewData["StateProvinceId"] as SelectList, new {@class = "State"})
</td>
<td>
    @Html.EditorFor(a => a.PostalCode, new {@class = "ZipCode"})
</td>
<td>
    @Html.DropDownList("CountyId", ViewData["CountyId"] as SelectList, new {@class = "County"})
</td>

控制器示例

//
// GET: /Customer/Manage/5
public ActionResult Manage(Guid id)
{
    CustomerModel customer = DataService.GetCustomer(id, HttpContext.User.Identity.Name);
    if (customer == null)
    {
        return HttpNotFound();
    }
    ViewBag.AddressTypeId = new SelectList(DataService.GetOrganizationAddressTypes(HttpContext.User.Identity.Name), "Id", "Name");
    ViewBag.PhoneTypeId = new SelectList(DataService.GetOrganizationPhoneTypes(HttpContext.User.Identity.Name), "Id", "Name");
    ViewBag.StateProvinceId = new SelectList(DataService.GetStates(), "Id", "Name");
    ViewBag.CountyId = new SelectList(DataService.GetCounties(0), "Id", "Name");
    return View(customer);
}
