我正在嘗試編輯編輯中顯示的選定行中的所有行，但也按以下格式分組：注意：[] 代表復選框，在數據庫中為 true 或 falseA. 您在服用以下藥物時是否有這些癥狀？ Yes No Sometimes Not Sure After 21 days Indifferent(i) 撲熱息痛 [] [] [] [] [] [] ...(ii) Quninne [] [] [] [] [] [] ...B. 用冷水和以下藥物一起使用時，您的眼睛會閃爍嗎？ Yes No Sometimes Not Sure After 21 days Indifferent(i) 維生素 C [] [] [] [] [] [] ...(ii) Quninne [] [] [] [] [] [] ,,,我的 POCO 設計是這樣的：public class QuestionCategory{ public int QuestionCategoryID {get; set;} public string Name {get; set;} ...}public class Question{ public int ID {get; set;} public string Name {get; set;} public int QuestionCategoryID {get; set;} ...}在視圖中我可以按 QuestionCategoryID 對問題進行分組，現在的問題是如何列出所有問題并單擊一個按鈕進行編輯。所以我決定制作一個我想要實現的線框。

請參閱下面的我的解決方案。我為問題、子問題和選項創建了 3 個表。選項與父問題相關聯（假設所有問題的選項都相同）。問題和子問題顯示在文本框中（以使其可編輯）。您可以修改它以適合您的需要。希望這可以幫助。
這是我的觀點：
@model List<QuestionsTest.Models.QuestionModel>
<form method="post">
<table class="table">
@for (int i = 0; i < Model.Count; i++)
{
<tr>
<td colspan="2">
@Html.HiddenFor(model => Model[i].Id, new { @class = "form-control" })
<b> @Html.TextBoxFor(model => Model[i].Question, new { @class = "form-
control" })</b>
</td>
</tr>
for (int j = 0; j < Model[i].SubQuestions.Count; j++)
{
<tr>
<td>
@Html.HiddenFor(model => Model[i].SubQuestions[j].Id, new { @class =
"form-control" })
@Html.HiddenFor(model => Model[i].SubQuestions[j].ParentQuestionId, new {
@class = "form-control" })
@Html.TextBoxFor(model => Model[i].SubQuestions[j].SubQuestion1, new {
@class = "form-control" })
</td>
<td>
@for (int k = 0; k < Model[i].Options.Count; k++)
{
@Html.RadioButtonFor(model => Model[i].Options[k].QuestionOption,
Model[i].Options[k].QuestionOption)@Model[i].Options[k].QuestionOption
}
</td>
</tr>
}
}
</table>
<input class="btn-block btn-success" type="submit" value="Update" />
這是我的控制器：
public ActionResult Questions()
{
var questions = _laraTestEntities.Questions.ToList();
var questionModel = new List<QuestionModel>();
questions.ForEach(q =>
{
var subQuestions = _laraTestEntities.SubQuestions.Where(s => s.ParentQuestionId == q.Id).ToList();
var options = _laraTestEntities.Options.ToList();
var model = new QuestionModel
{
Id = q.Id,
Question = q.Question1,
SubQuestions = subQuestions,
Options = options
};
questionModel.Add(model);
});
return View(questionModel);
}
[HttpPost]
public ActionResult Questions(List<QuestionModel> Model)
{
Model.ForEach(q =>
{
var questionDetail = _laraTestEntities.Questions.Find(q.Id);
if (questionDetail != null)
{
questionDetail.Question1 = q.Question;
q.SubQuestions.ForEach(s =>
{
var subQuestionDetail = _laraTestEntities.SubQuestions.Find(s.Id);
if (subQuestionDetail != null)
{
subQuestionDetail.SubQuestion1 = s.SubQuestion1;
}
});
_laraTestEntities.SaveChanges();
}
});
return View(Model);
}
模型：
public class QuestionModel
{
public int Id { get; set; }
public string Question { get; set; }
public List<SubQuestion> SubQuestions { get; set; }
public List<Option> Options { get; set; }
}
public class SubQuestion
{
public int Id { get; set; }
public int ParentQuestionId { get; set; }
public string SubQuestion1 { get; set; }
public virtual QuestionCategory QuestionCategory { get; set; }
}
public class Option
{
public int Id { get; set; }
public string OptionTitle { get; set; }
}
