mvc 3でラベル値を取得する方法は？

Question

モデルで：コントローラーで

public class DataViewModel 
{ 
    public IList<RowsCollection> Rows { get; set; } 

    public PaiementMethod PaiementMethod { get; set; } 

} 
public class RowsCollection 
{ 
    public string ID { get; set; } 
    public string Question { get; set; } 
} 

public enum PaiementMethod 
{ 
    Cash, 
    CreditCard, 
} 

- インデックスのActionResult私は私のモデルを返し、そのビューにページをレンダリングしているようなもの：提出フォームアクションイベントで

 @model WebNexpo.Controllers.DataViewModel 
    @using (Html.BeginForm("Save", "page", FormMethod.Post, new { id = "saves"})) 
     { 
     foreach (var item in Model.Rows) 
     { 
      @Html.Label(item.Question) 
      <label for="paiement_cash"> 
      Cash</label> 
     @Html.RadioButtonFor(m => m.PaiementMethod, "Cash", new { name = "paiement_cash" + @item.ID + "", id = "radioID" + @item.ID + "", Group = "Group" + @item.ID + "" }) 
     <label for="paiement_cc"> 
      Credit card</label> 
     @Html.RadioButtonFor(m => m.PaiementMethod, "CreditCard", new { name = "paiement_cc" + @item.ID + "", id = "radioname" + @item.ID + "", Group = "Group" + @item.ID + "" }) 

     } 
     <input id="Saveser" type="submit" value="" class="button1" /> 
    } 

：

 [HttpPost] 
    public ActionResult Save(DataViewModel model) 
    { 
     if (ModelState.IsValid) 
     { 
      //want to read all the label which selected rediobutton. 
       means suppose 4 question render on page and user have selected only 2 
      question of the answer.so How can accomplish here? 
     } 
     return RedirectToAction("Index", new {value = "123"}); 
    } 

Answer 1

ここにはいくつかの矛盾があります。その後、

public class DataViewModel 
{ 
    public IList<RowsCollection> Rows { get; set; } 
} 

public class RowsCollection 
{ 
    public string ID { get; set; } 
    public string Question { get; set; } 
    public PaiementMethod PaiementMethod { get; set; } 
} 

と：あなたは、おそらくにあなたのビューモデルを再編成したいので、行ごとに、2つのラジオボタンをレンダリングしている

@model DataViewModel 
@using (Html.BeginForm("Save", "page", FormMethod.Post, new { id = "saves"})) 
{ 
    for (var i = 0; i < Model.Rows.Count; i++) 
    { 
     <div> 
      @Html.HiddenFor(x => x.Rows[i].ID) 
      @Html.LabelFor(x => x.Rows[i].Question) 
      @Html.EditorFor(x => x.Rows[i].Question) 

      @Html.Label("payment_cash" + i, "Cash") 
      @Html.RadioButtonFor(m => m.Rows[i].PaiementMethod, "Cash", new { id = "payment_cash" + i }) 

      @Html.Label("payment_cc" + i, "Credit card") 
      @Html.RadioButtonFor(m => m.Rows[i].PaiementMethod, "CreditCard", new { id = "payment_cc" + i }) 
     </div> 
    } 
    <input id="Saveser" type="submit" value="" class="button1" /> 
} 

し、最終的に：

[HttpPost] 
public ActionResult Save(DataViewModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     // model.Rows[0].PaiementMethod will contain the selected payment method for the first question 
     // model.Rows[1].PaiementMethod will contain the selected payment method for the second question 
     // ... 
    } 
    return RedirectToAction("Index", new { value = "123" }); 
} 

かもしあなたのビューモデルをそのままにして、ビューのループの外側にラジオボタンを残しておけば、1つの支払い方法が必要になります。同様に：

@using (Html.BeginForm("Save", "page", FormMethod.Post, new { id = "saves" })) 
{ 
    for (var i = 0; i < Model.Rows.Count; i++) 
    { 
     <div> 
      @Html.HiddenFor(x => x.Rows[i].ID) 
      @Html.LabelFor(x => x.Rows[i].Question) 
      @Html.EditorFor(x => x.Rows[i].Question) 
     </div> 
    } 

    @Html.Label("payment_cash", "Cash") 
    @Html.RadioButtonFor(x => x.PaiementMethod, "Cash", new { id = "payment_cash" }) 

    @Html.Label("payment_cc", "Credit card") 
    @Html.RadioButtonFor(x => x.PaiementMethod, "CreditCard", new { id = "payment_cc" }) 

    <input id="Saveser" type="submit" value="" class="button1" /> 
}
