MVC3 @ Html.RadioButtonfor通数据视图控制器 [英] MVC3 @Html.RadioButtonfor Pass data from view to controller

问题描述

基本上，我想是创建一个反馈表与它有四个答案使用MVC（单选按钮）的问题。

Basically what I am trying is to create a feedback form with a question which has four answers (Radio Button) using MVC.

在View ：我能够获得鉴于与单选按钮的问题和答案，每个答案

In View: I am able to get questions and answers in view with radiobutton to each answer.

在控制器：我很困惑在这里

我想送所选问题和放大器;有从View回答到控制器。

I would like to send selected question & there answers from View to controller.

我的看法

@model  IEnumerable SQLOperation.Models.QuestionClass.Tabelfields


@{int i = 0;}


     @foreach (var item in Model)
     {
     using (Html.BeginForm("Question", "home", new {email=item.Email}))
     {   

         @Html.DisplayFor(modelItem => item.QuestionName,item)

         <br /><br />   
         if (item.Option1 != "")
         {
                    @Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option1, item)                
                    @Html.DisplayFor(modelItem => item.Option1)
                    <br /><br />                
         }

         if (item.Option2 != "")
         {
                    @Html.RadioButtonFor(modelItem => item.SelectedOption, item.Option2)              
                    @Html.DisplayFor(modelItem => item.Option2)
                    <br /><br />
         }

         if (item.Option3 != "")
         {           
                    @Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option3)              
                    @Html.DisplayFor(modelItem => item.Option3)
                    <br /><br />
         }


         if (item.Option4 != "")
         {
                    @Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option4)             
                    @Html.DisplayFor(modelItem => item.Option4) 
                    <br /><br />     
         }
         i = (Int16)i + 1;


         if (Model.Count() == i)
         {
                <input name="btnsumbit" type="submit" value="Submit Feedback" 
                style="font-family:Segoe UI Light;font-size:medium;"/>
         }
     }
 }

我的控制器

 [HttpGet]
    public ActionResult Question(string email)
    {
        var tf = new QuestionClass.Tabelfields();

        IList<QuestionClass.Tabelfields> viewmodel = new List<QuestionClass.Tabelfields>();
        var q = QuestionClass.getallQuestion(email).ToList();

        foreach (SQLOperation.Models.Question item in q)
        {
            QuestionClass.Tabelfields viewItem = new QuestionClass.Tabelfields();

            viewItem.Email = item.Email;
            viewItem.QuestionID = item.QuestionID;
            viewItem.QuestionName = item.QuestionName;
            viewItem.Option1 = item.Option1;
            viewItem.Option2 = item.Option2;
            viewItem.Option3 = item.Option3;
            viewItem.Option4 = item.Option4;                
            viewmodel.Add(viewItem);
        }
         return View(viewmodel);
    }

    [HttpPost, ActionName("Question")]
    public void Question(string Email,QuestionClass.Tabelfields tf)
    {

    }

我的模型

public class QuestionClass

{

  public static FeedbackDatabaseDataContext context = new FeedbackDatabaseDataContext();
    public class Tabelfields : Question
    {
        //public decimal QuestionID { get; set; }
        //public string Email { get; set; }
        //public string QuestionName { get; set; }
        //public string Option1 { get; set; }
        //public string Option2 { get; set; }
        //public string Option3 { get; set; }
        //public string Option4 { get; set; }
        public int SelectedOption { get; set; }
    }


    public static List<Question> getallQuestion(string email)
    {
        var list = (from q in context.Questions where q.Email == @email select q);

        return list.ToList();
    }

}

我没有得到这个问题，它的选择与控制相应的电子邮件选项。

I didn't get the question and it's selected option with appropriate Email in controller.

怎样才能得到它的控制器？

How can I get it in controller?

推荐答案

要，开始与包括断点在您的视图，并检查是否正在通过与否的值。

To, start with include a breakpoint in your view and check if the values are being passed or not.

接下来，你的方法签名从

Next, change your method signature from

 public void Question(string Email,QuestionClass.Tabelfields tf)

到

 public void Question(string email, QuestionClass.Tabelfields tf)

另外，我看你已经使用了一些奇怪的语法（考虑M还新MVC），您可以简单用这种

Also, I see you have used some strange syntax ( considering m also new to MVC ) where you could have simply used this

@Html.DisplayFor(modelItem => item.QuestionName)

而不是这种

@Html.DisplayFor(modelItem => item.QuestionName,item)

和也，我已经看到您资料，我知道你是新来的StackOverflow，所以欢迎计算器！你可能需要阅读这＆放大器; 这的为好。干杯！

and also, I have seen you profile, I know you are new to StackOverflow, so Welcome to StackOverflow ! you might want to read this & this as well. Cheers !

更新：

您正在使用这个用于显示一个单选按钮...

You are using this for displaying a radio button...

@Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option1, item)

什么item.Option1，我可以看到你注释掉Opion1,2,3,4。或者你还在使用它们？

what is item.Option1, I can see you have commented out Opion1,2,3,4. Or are you still using them ?

实现，这将是这样的一个非常简单的方法。

A very simple way of implementing this would be something like this

@Html.RadioButtonFor(modelItem =>item.SelectedOption, "Option1")
@Html.RadioButtonFor(modelItem =>item.SelectedOption, "Option2")
@Html.RadioButtonFor(modelItem =>item.SelectedOption, "Option3")

或者你也可以使用，

or you can also use,

@Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option1)
@Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option2)
@Html.RadioButtonFor(modelItem =>item.SelectedOption, item.Option3)

规定值item.Option1 / 2/3/4是存在的，所有的人都不同。

provided values exist in item.Option1/2/3/4 and are all of them are different.
