如何验证asp.net mvc 3中的多个模型？

Question

我有一个简单的模型，如：

public class AppointmentModel 
    { 
     private static List<SampleModel> _list; 

     public string ClientName { 
     get; 
     set; 
     } 

     [DataType(DataType.Date)] 
     public DateTime Date { 
     get; 
     set; 
     } 

     public bool TermsAccepted { 
     get; 
     set; 
     } 

     public List<SampleModel> SampleModelList { 
     get; 
     set; 
     } 

     public static List<SampleModel> GetSampleList() { 
     if (_list == null) { 

      _list = new List<SampleModel>(0); 

      _list.Add(new SampleModel { 
       Id = 1, 
       Name = "Test", 
       IsChecked = false 
      }); 

      _list.Add(new SampleModel { 
       Id = 2, 
       Name = "Another test", 
       IsChecked = true 
      }); 

      _list.Add(new SampleModel { 
       Id = 3, 
       Name = "All test", 
       IsChecked = false 
      }); 
     } 

     return _list; 
     } 
    } 

SampleModel样子（创建它来模拟复选框上输入）：

public class SampleModel 
    { 
     public int Id { 
     get; 
     set; 
     } 

     public string Name { 
     get; 
     set; 
     } 

     public bool IsChecked { 
     get; 
     set; 
     } 
    } 

在我看来，我实现：

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<SimpleAppWithModelBinding.Models.AppointmentModel>" %> 

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> 
    Page 
</asp:Content> 

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 

<h2>Page</h2> 

    <% using (Html.BeginForm(FormMethod.Post)) { %> 
     <%:Html.ValidationSummary()%> 

     <p>Name: <%: Html.EditorFor(model => model.ClientName)%></p> 
     <p>Date: <%: Html.EditorFor(model => model.Date)%></p> 
     <p><%: Html.EditorFor(model => model.TermsAccepted)%> Accept terms</p> 

     <%-- here I put the checkbox list using editor template --%> 
     <%: Html.Action("RenderPartialSample") %> 

     <input type="submit" value="Test" /> 
    <%} %> 

</asp:Content> 

和控制器端HomeController：

 public ActionResult Page() { 

     return View(); 
     } 

     // explicit validate model 
     [HttpPost] 
     public ActionResult Page(AppointmentModel model) { 

     // do some verification here 

     if (model.SampleModelList == null || (model.SampleModelList != null && model.SampleModelList.Count == 0)) { 
      ModelState.AddModelError("SampleModelList", "Please check something !"); 
     } 

     if (ModelState.IsValid) { 
      //do something here 
      return View("Completed", model); 
     } else { 
      return View("Page", model); 
     } 
     } 


     public PartialViewResult RenderPartialSample() { 
     List<SampleModel> model = new List<SampleModel> { 
      new SampleModel{ 
       Id = 1, 
       IsChecked = true, 
       Name = "Test" 
      }, 

      new SampleModel{ 
       Id = 2, 
       IsChecked = false, 
       Name = "Test1" 
      }, 

      new SampleModel{ 
       Id = 3, 
       IsChecked = false, 
       Name = "Test2" 
      } 
     }; 

     AppointmentModel a = new AppointmentModel(); 
     a.SampleModelList = model; 

     return PartialView("SamplePartialView", a.SampleModelList); 
     } 

问题：

当我按下提交，该public ActionResult Page(AppointmentModel model)给了我一个模型，他有SampleModelList空，总是为空。我想从模型列表中检查输入，但由于局部视图可能不起作用。

如何验证我的情况下的两个模型？或者对我来说最好的办法是什么，也许我的做法不好。

请帮助:)

UPDATE：

SamplePartialView包含：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<SimpleAppWithModelBinding.Models.SampleModel>>" %> 

<%: Html.EditorForModel() %> 

和模板：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<SimpleAppWithModelBinding.Models.SampleModel>" %> 

<%: Html.HiddenFor(x => x.Id) %> 
<%: Html.CheckBoxFor(x => x.IsChecked, new { 
     value = Model.Id 
    })%> 
<%: Html.LabelFor(x => x.IsChecked, Model.Name) %>

你没有表现出SamplePartialView部分，但我是苏请注意，您并不尊重您输入字段的命名约定。为了尊重默认模型联编程序的naming convention，它们没有加上前缀SampleModelList。

这里面的部分，你应该有一个看起来像这样输入字段：

<input type="text" name="SampleModelList[0].Id" value="1" /> 
<input type="text" name="SampleModelList[0].Name" value="name 1" /> 

<input type="text" name="SampleModelList[1].Id" value="1" /> 
<input type="text" name="SampleModelList[1].Name" value="name 1" /> 

... 

看看你的形式呈现的标记，并确保你有尊重这个约定。

为了尊重你可以设置模板前缀命名约定，无论是孩子控制器动作中渲染的部分：

ViewData.TemplateInfo.HtmlFieldPrefix = "SampleModelList"; 
return PartialView("SamplePartialView", a.SampleModelList); 

或内部部分本身，如果你喜欢：

<%@ Control 
    Language="C#" 
    Inherits="System.Web.Mvc.ViewUserControl<List<SimpleAppWithModelBinding.Models.SampleModel>>" 
%> 
<% ViewData.TemplateInfo.HtmlFieldPrefix = "SampleModelList"; %> 
<%= Html.EditorForModel() %>
