asp.net – 如何使用嵌套的视图模型获取EditorFor的数据

我有两个嵌套的视图模型：

><％= Html.EditorFor(x => x.DisplayEntitiesWithRadioboxesViewModel)％>< br />

它位于其父(StructureViewModel)中,我可以轻松填充嵌套的ViewModel并将其传递给主视图：

在控制器内 – 示例

var moveDepartment = new StructureViewModel();
moveDepartment.DisplayEntitiesWithRadioboxesViewModel = fullDepartmentList.Select(x => new DisplayEntityViewModel
            {
                Id = x.Id,Path = x.Path,PathLevel = x.PathLevel,Description = x.Description,});

return View(moveDepartment);

EditorTemplete – 示例

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Site.Areas.Administration.ViewModel.DisplayEntityViewModel>>" %>
<table class="aligncenter"><%
  if (Model != null)
  {
    foreach (var entity in Model)
    {%>
      <tr class="tRow">
        <td style="text-align:left; text-indent:<%=Html.Encode(entity.PathLevel)%>em">
          <%=Html.Encode(entity.Description)%>
          <%=Html.RadioButton("radiobutton",entity.Id)%>
        </td>              
      </tr><%    
    }
  }%>
</table>


namespace Site.Areas.Administration.ViewModel
{
    public class DisplayEntityViewModel
    {
        public int Id { get; set; }
        public string Path { get; set; }
        public string PathLevel { get; set; }
        public string Description { get; set; }   
    }
}

但是,当我尝试撤回此信息时,嵌套的ViewModel为null：

[HttpPost]
public ActionResult Move(StructureViewModel StructureViewModel)

当我将鼠标悬停在StructureViewModel上时,它只包含父ViewModel中的数据集.例如：可以看到隐藏值,但DisplayEntitiesWithRadioboxesViewModel = null.

我知道如何访问DisplayEntitiesWithRadioboxesViewModel的唯一方法是使用FormCollection并遍历FormCollection并从嵌套的ViewModel中提取我需要的信息.

然而,这似乎并不正确,因为我在I处发现必须使用FormCollection中的值重新填充DisplayEntitiesWithRadioboxesViewModel,例如,如果发生错误并且需要将用户发送回同一个View.

我试过搜索网页/书籍但找不到解决方案.

有没有更好的办法？

在此先感谢您的帮助.

And why did you use an EditorFor for a
simple dropdown,which is easily to
use with DropDownFor

现在已经改变为使用DropDownFor.

what is the Key of the
DisplayEntitiesWithRadioboxesViewModel
value in FormCollection

{string[3]}
[0] = "DisplayEntitiesWithRadioboxesViewModel.radiobutton"
[1] = "Action"
[2] = "OldParentId"
