目前，我有一个带有多个问题的问卷的工作原型，每个问题都有多个答案选择。一切都显示并保存得很好。但是，我现在想在我的编辑视图中将问题/答案分组到“部分”中。我尝试了几种不同的方法，但似乎都没有正常工作。没有节的工作代码如下：

编辑查看进度报告：

<div class="form-group">
    @Html.LabelFor(model => model.ReportAnswers, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.ReportAnswers)
    </div>
</div>

ReportAnswers.cshtml（编辑器模板）

<h3>
    Question
</h3>

<p>
    @Html.DisplayFor(x => x.Question.QuestionText)
</p>
@Html.HiddenFor(model => model.QuestionID)
@Html.HiddenFor(model => model.ReportID)

@foreach (var answer in Model.Question.PossibleAnswers)
{
    var id = string.Format("answer-{0}", answer.AnswerID);
    <p>
        @Html.HiddenFor(model => model.ReportAnswerID)

        @Html.RadioButtonFor(m => m.AnswerID, answer.AnswerID, new { id = id })
        <label for="@id">@answer.AnswerText</label>
    </p>
}

编辑控制器：

[HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit(ProgressReport progressReport)
    {
        if (ModelState.IsValid)
        {
            db.Entry(progressReport).State = EntityState.Modified;
            db.SaveChanges();

            foreach (ReportAnswer answer in progressReport.ReportAnswers)
            {
                        if (answer.QuestionID != null && answer.AnswerID != null)
                        {
                            db.Entry(answer).State = EntityState.Modified;
                            db.SaveChanges();
                        }                   

            }

            return RedirectToAction("Index");
        }
        ViewBag.ClientID = new SelectList(db.Clients, "ClientID", "ID", progressReport.ClientID);
        return View(progressReport);
    }

数据结构是 Sections -> Questions -> Answers 然后我有一个 ProgressReport 表，其中包含 QuestionID 和 AnswerID

我试图在视图中进行 Groupby，但不确定如何正确调用 Editortemplate。其实我是可以用的，但是结果并没有想象中的那么好。该代码是：

@foreach (var group in Model.ReportAnswers.GroupBy(s => s.Question.SectionID))

谢谢！

您将更好地创建表示要在视图中显示的数据的视图模型

public class ReportVM
{
  public int ID { get; set; }
  // other properties or Report for display/editing
  public List<SectionVM> Sections { get; set; }
}
public class SectionVM
{
  public int ID { get; set; }
  public string Name { get; set; }
  // other properties or Report for display/editing
  public List<QuestionVM> Questions{ get; set; }
}
public class QuestionVM
{
  public int ID { get; set; }
  public string Title { get; set; }
  public int SelectedAnswer { get; set; }
  public List<Answer> PossibleAnswers { get; set; }
}

在控制器中，使用您的.GroupBy()查询来构建您的视图模型并添加每个部分及其相关的问题/答案

然后添加一个EditorTempateforSectionVM 

@model SectionVM
@Html.HiddenFor(m = > m.ID)
<h2>@Html.DisplayFor(m => m.Name)</h2>
@Html.EditorFor(m => m.Questions) // uses an EditorTemplate for QuestionVM (i.e. as per your current ReportAnswers template

在主视图中

@Html.EditorFor(model => model.Sections)

我能够开发出一个解决方案……合适与否……不知道……但它确实有效。随意批评。我欢迎它。:)

进度报告视图模型：

public class ProgressReportViewModel
{
    public int ReportID { get; set; }
    public DateTime ReportDateSubmitted {get; set;}
    public List<ReportAnswer>[] ReportAnswerSection { get; set; }
    public string[] SectionHeadings { get; set; }
    public string[] SectionDescriptions { get; set; }
}

编辑控制器：

public ActionResult Edit(int? id)
    {
        var viewModel = new ProgressReportViewModel();

       //  Get the section in order of defined display order
        var questionsection = (from s in db.QuestionSections
                                orderby s.SectionDisplayOrder
                                select new{
                                    s.SectionName,
                                    s.SectionDesc
                                });

        viewModel.SectionHeadings = new string[11];
        viewModel.SectionDescriptions = new string[11];
        viewModel.ReportAnswerSection = new List<ReportAnswer>[11];

        int i = 0;
        foreach(var section in questionsection)
        {
            //  Loop through sections and get the name, desc and the questions/answers
            viewModel.SectionHeadings[i] = section.SectionName.ToString();
            viewModel.SectionDescriptions[i] =   section.SectionDesc;
            viewModel.ReportAnswerSection[i] = db.ReportAnswers.Where(q => q.Question.SectionID == i+1 && q.ReportID == id).Include(s => s.Question.QuestionSection).OrderBy(q => q.Question.DisplayOrder).ToList();
            i=i+1;
        }

        var report = (from r in db.ProgressReports
                      where r.ReportID == id
                      select new
                      {
                          r.ReportID,
                          r.ReportDateSubmitted,
                          r.ClientID
                      }).SingleOrDefault();
        viewModel.ReportID = report.ReportID;
        viewModel.ReportDateSubmitted = report.ReportDateSubmitted ?? DateTime.MinValue;


        return View(viewModel);
    }



    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit(ProgressReportViewModel progressReport)
    {
        if (ModelState.IsValid)
        {
            ProgressReport PR = db.ProgressReports.Where(x => x.ReportID == progressReport.ReportID).SingleOrDefault();


            //db.ProgressReports.Attach(progressReport);

            db.Entry(PR).State = EntityState.Modified;
            db.SaveChanges();

            for (var i = 0; i <= 10; i++ )
            {
                foreach (ReportAnswer answer in progressReport.ReportAnswerSection[i]) //.ReportAnswers)
                {
                    SaveAnswers(answer);
                }
            }

            return RedirectToAction("Index", "Home");
        }
        return View(progressReport);
    }

ReportAnswers 编辑器模板

<h3>
Question
</h3>

<p>
@Html.DisplayFor(x => x.Question.QuestionText)
</p>
@Html.HiddenFor(model => model.QuestionID)
@Html.HiddenFor(model => model.ReportID)

@foreach (var answer in Model.Question.PossibleAnswers)
{
var id = string.Format("answer-{0}", answer.AnswerID);
<p>
    @Html.HiddenFor(model => model.ReportAnswerID)

    @Html.RadioButtonFor(m => m.AnswerID, answer.AnswerID, new { id = id })
    <label for="@id">@answer.AnswerText</label>
</p>
}

编辑视图：

@for(var i = 0; i<=10; i++)
    {
        <h4>@Html.DisplayFor(model => model.SectionHeadings[i]) </h4>
        <p>@Html.DisplayFor(model => model.SectionDescriptions[i]) </p>
        @Html.EditorFor(model => model.ReportAnswerSection[i])
    }

我选择做这些数组是因为我至少需要截取一个部分来做一些特别的事情。否则所有其他部分都是典型的。这似乎可行，但如前所述，我欢迎任何人提出的任何批评。

祝你有美好的一天！
