2012年8月14日下午12:05更新 我将尝试解释我的情况，希望有人可以指出我正确的方向。

我的项目中有一个表单，其中包含几个表，所有表都已经设置了关系。以下是相关的模型。

namespace QQAForm.Models
 {
  public class AuditSchedule
    {
    public virtual int AuditScheduleID { get; set; }
    public virtual Nullable<DateTime> audit_completed_date { get; set; }
    public virtual string gl_cmp_key { get; set; }
    public virtual string audit_year { get; set; }
    public virtual string ar_ship_key { get; set; }
    public virtual string ar_ship_name { get; set; }
    public virtual string im_adres_city { get; set; }
    public virtual string im_adres_state { get; set; }
    public virtual string audit_type { get; set; }
    public virtual string audit_no { get; set; }
    public virtual string audit_group { get; set; }
    public virtual string Footage { get; set; }
    public virtual string Rolling3MosFootage { get; set; }
    public virtual string snp_SalesRep8 { get; set; }
    public virtual string epg_sales_rep_accountable { get; set; }
    public virtual string tech_service_rep { get; set; }
    public virtual string audit_done_by { get; set; }
    public virtual Nullable<DateTime> audit_recieved_date { get; set; }
    public virtual string audit_notes { get; set; }
    public virtual string audit_pdf { get; set; }
    public virtual string updated { get; set; }
    public virtual string hidden { get; set; }
    public virtual string en_stats_key { get; set; }
    public virtual string Control_ID { get; set; }
    public virtual Nullable<DateTime> audit_date { get; set; }
    public virtual string contacts_present { get; set; }
    public virtual string audit_furnished_to { get; set; }
    public virtual string spacer_type { get; set; }



   }
}

MainQuestion：

namespace QQAForm.Models
{
public class MainQuestion
    {
    public virtual int MainQuestionID { get; set; }
    public virtual int SubCategoryID { get; set; }
    public virtual int ReferenceNo { get; set; }
    public virtual int DisplayIndex { get; set; }
    public virtual int SuggestionID { get; set; }
    public virtual string Question { get; set; }

    public virtual SubCategory SubCategory { get; set; }

    public virtual ICollection<Suggestion> suggestions { get; set; }
    public virtual ICollection<DocumentLink> documentLink { get; set; }
    }
 }

儿童问题：

namespace QQAForm.Models
{
public class ChildQuestion
    {
    public virtual int ChildQuestionID { get; set; }
    public virtual int MainQuestionID { get; set; }
    public virtual int ReferenceNo { get; set; }
    public virtual int DisplayIndex { get; set; }
    public virtual string QuestionText { get; set; }
    public virtual string UserEntityType { get; set; }
    public virtual string UserEntityTexts { get; set; }

    public virtual MainQuestion MainQuestion { get; set; }



    }
 }

建议：

namespace QQAForm.Models
{
public class Suggestion
    {
    public virtual int SuggestionID { get; set; }
    public virtual int MainQuestionID { get; set; }
    public virtual int DisplayIndex { get; set; }
    public virtual string ReferenceNo { get; set; }
    public virtual string Suggestions { get; set; }

    public virtual MainQuestion MainQuestion { get; set; }
   }
}

主要答案：

namespace QQAForm.Models
{
public class MainAnswer
    {
    public virtual int MainAnswerID { get; set; }
    public virtual int AuditScheduleID { get; set; }
    public virtual int MainQuestionID { get; set; }
    public virtual string Score { get; set; }
    public virtual string AdditionalNotes { get; set; }

    public virtual AuditSchedule AuditSchedule { get; set; }
    public virtual MainQuestion MainQuestion { get; set; }

    }
 }

我很难弄清楚如何从一个表中显示一个问题，该表与另一个表有子问题的关系和答案的复选框。答案很简单是，否和N / A.它们也被保存在不同的表格中。我在数据表中拥有所有这些的原因是它们必须是可编辑的，或者如果我想添加到这些区域。  这就是页面应该是什么样子。我已经使用了文本来查找页面。

布局：

<html>
<head>
<title>@ViewBag.Title</title>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript">  </script>
</head>
<body>
<div id="head" class="container">
    @Html.Partial("Header")
 </div>
    <div class="container">
        <div id="main">
            <ul id="breadcrumbs">

            </ul>
            <div id="formTopCol">
              @RenderBody()
              @*@Html.Partial("_Audit")*@  
            </div>
            <div id="formBottomCol">
                    @Html.Action("_SubCategory")

                <div id="formBottomRightCol">
                    @Html.Action("_Forms")
                    @*@RenderBody()*@
                </div>
                <div style="clear:left;"></div>
            </div>
        </div>
    </div>  
    <div class="container">
       @Html.Partial("Footer")
  </div>
 </body>
 </html>

这就是它的样子： enter image description here

我在global.asax中设置了一个字符串来接受审计记录，然后提出主要问题。有一个侧面菜单，将选择问题区域。这是在一个视图中完成的，其中审核计划是正文，侧面菜单和表单问题/答案是部分的Html.Action（）。

全球守则：

            routes.MapRoute(
            "AuditSchedule", // Route name

            "AuditSchedule/Audit/{id}/{section}", // URL with parameters
            new { controller = "AuditSchedule", action = "Audit", id = UrlParameter.Optional, section = UrlParameter.Optional } // Parameter defaults

        );

我曾尝试使用视图模型，但我不能让它工作。对于C＃编码的数据库，我真的很弱。

以下是我正在使用控制器的模型：

namespace QQAForm.ViewModels
{
public class AuditFormEdit
{
    public Models.MainAnswer ScoreInstance { get; set; }

    public List<ScoreCardCheckBoxHelper> ScoreCardCheckBoxHelperList { get; set; }

    public void InitializeScoreCheckBoxHelperList(List<Models.Score> ScoreList)
    {
        if (this.ScoreCardCheckBoxHelperList == null)
            this.ScoreCardCheckBoxHelperList = new List<ScoreCardCheckBoxHelper>();

        if (ScoreList != null
            && this.ScoreInstance != null)
        {
            this.ScoreCardCheckBoxHelperList.Clear();
            ScoreCardCheckBoxHelper scoreCardCheckBoxHelper;
            string scoreTypes =
                string.IsNullOrEmpty(this.ScoreInstance.Score) ?
                string.Empty : this.ScoreInstance.Score;
            foreach (Models.Score scoreType in ScoreList)
            {
                scoreCardCheckBoxHelper = new ScoreCardCheckBoxHelper(scoreType);
                if (scoreTypes.Contains(scoreType.ScoreName))
                    scoreCardCheckBoxHelper.Checked = true;
                this.ScoreCardCheckBoxHelperList.Add(scoreCardCheckBoxHelper);
            }
        }
    }

    public void PopulateCheckBoxsToScores()
    {
        this.ScoreInstance.Score = string.Empty;
        var scoreType = this.ScoreCardCheckBoxHelperList.Where(x => x.Checked)
                              .Select<ScoreCardCheckBoxHelper, string>(x => x.ScoreName)
                              .AsEnumerable();
        this.ScoreInstance.Score = string.Join(", ", scoreType);
    }


    public class ScoreCardCheckBoxHelper : Models.Score
    {
        public bool Checked { get; set; }

        public ScoreCardCheckBoxHelper() : base() { }

        public ScoreCardCheckBoxHelper(Models.Score scoreCard)
        {
            this.ScoreID = scoreCard.ScoreID;
            this.ScoreName = scoreCard.ScoreName;
        }
    }

}
}

控制器部分：

        //get
    public ActionResult _Forms(int id)
    {
        AuditFormEdit viewModel = new AuditFormEdit();
        //viewModel.ScoreInstance = _db.MainAnswers.Single(r => r.AuditScheduleID == id);
        viewModel.InitializeScoreCheckBoxHelperList(_db.Scores.ToList());
        return View(viewModel);
    }

    //post
    [HttpPost]
    public ActionResult _Forms(int id, AuditFormEdit viewModel)
    {
        if (ModelState.IsValid)
        {
            viewModel.PopulateCheckBoxsToScores();
            _db.Entry(viewModel.ScoreInstance).State = System.Data.EntityState.Modified;
            _db.SaveChanges();
            return RedirectToAction("/");
        }
        else
        {
            return View(viewModel);
        }
    }

正如我之前所述，ViewModel不起作用，因为我要求一个不存在的id。现在，视图模型只有代码来填充答案的复选框。

添加了视图代码08/14/2012下午1:00

表单部分视图主要是测试，但脚本补充复选框代码

@{ Layout = null; }
@model QQAForm.ViewModels.AuditFormEdit

<table width="698" border="2" cellpadding="2">
<tr>
<td align="center"><b>Section</b><br />1.0</td>
<td><b>Glass edge damage noted. (shells, flakes, sharks teeth)</b>
<br /><br />

@Html.CheckBox("suggestion1") &nbsp;
It was noted that there was a significant amount of glass edge damage observed on the  IG units being produced.  
This glass edge damage may lead to a significantly high glass breakage rate in IG unit handling, in the glazing operation and in service.
[MAJOR CONCERN]
The cause of this glass edge damage should be determined and efforts made to eliminate the damage. 
<br /><br />
@Html.CheckBox("suggestion2") &nbsp;
The glass edge should be smooth and free of chips, flakes, wings, or other damage. Damaged edges may result in stress cracks or premature IG unit failure.
[MAJOR CONCERN]
<br /><br />

<label>Additional Notes:</label><br />
@Html.TextArea("Additional Notes")
<br />
</td>
<td>
        @for (int index = 0; index < Model.ScoreCardCheckBoxHelperList.Count; index++)
        {

            @Html.CheckBoxFor(m => m.ScoreCardCheckBoxHelperList[index].Checked)
            @Html.LabelFor(m => m.ScoreCardCheckBoxHelperList[index], Model.ScoreCardCheckBoxHelperList[index].ScoreName)
            @Html.HiddenFor(m => m.ScoreCardCheckBoxHelperList[index].ScoreID)
            @Html.HiddenFor(m => m.ScoreCardCheckBoxHelperList[index].ScoreName)


        }

 </td>
 </tr>
</table>

这是侧面菜​​单的部分：

@{ Layout = null; }

@model IEnumerable<QQAForm.Models.SubCategory>
<div id="menuCol">
<h3>Audit Sections</h3>
        <ul>
            <li>

      @foreach (var item in Model)
        {

                <div class="sidemenu">
                    @Html.ActionLink(item.SubcategoryName, "Audit", new { section = item.SubCategoryID }, null)
                </div>

        }
            </li>
        </ul>   
</div>

这是身体：

@model QQAForm.Models.AuditSchedule
@{
ViewBag.Title = "Edit";
Layout = "~/Views/AuditSchedule/_FormLayout.cshtml";
}
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")"    type="text/javascript"></script>
@using (Html.BeginForm())
{
@Html.ValidationSummary(true)

<fieldset>
<table class="audit-display">
<tr>
<th>ID</th>
<th>Customer</th>
<th>City</th>
<th>State</th>
<th>EPG TSM Rep/NAM</th>
<th>EPG RSM (or NAM's VP)</th>
<th>Tech Rep</th>
<th>Audit Type</th>

</tr>

<tr>
<td>@Html.DisplayFor(m => m.AuditScheduleID)</td>
<td>@Html.DisplayFor(m => m.ar_ship_name)</td>
<td>@Html.DisplayFor(m => m.im_adres_city)</td>
<td>@Html.DisplayFor(m => m.im_adres_state)</td>
<td>@Html.DisplayFor(m => m.epg_sales_rep_accountable)</td>
<td>@Html.DisplayFor(m => m.snp_SalesRep8)</td>
<td>@Html.DisplayFor(m => m.tech_service_rep)</td>
<td>@Html.DisplayFor(m => m.audit_type)</td>


</tr>
 </table>
 <table class="audit-display">
<tr>
<th>Date</th>
<th>Contacts Present</th>
<th>Audit Furnished To</th>
<th>Audit Done By (If not sheduled)</th>
<th>Spacer's Used</th>

</tr>

<tr>
<td>@Html.DisplayFor(m => m.audit_date)</td>
<td>@Html.DisplayFor(m => m.contacts_present)</td>
<td>@Html.DisplayFor(m => m.audit_furnished_to)</td>
<td>@Html.DisplayFor(m => m.audit_done_by)</td>
<td>@Html.DisplayFor(m => m.spacer_type)</td>

</tr>
</table>

</fieldset>

为什么要在_Forms HttpPost操作中添加int id参数？你没有使用它，所以你不需要它，对吗？您也不会演示您的观看代码。
