避免在 mvc 视图中使用 mv 单选按钮中的编辑器模板进行 foreach [英] Avoid foreach using Editor Template in mv radiobutton within an mvc view

问题描述

我试图避免在 mvc 视图中使用 foreach，正如我在很多答案中看到的那样，这是一个很好的做法.但我并不完全了解如何实现它.

I'm trying to avoid using a foreach inside an mvc view, as I've seen in quite a few answers it's a good practice. But I'm not exactly getting how to achieve it.

我想使用银行列表，创建一堆单选按钮，以便发布其中一个(实际上是 id)

I would like to use a list of banks, to create a bunch of radio buttons in order to post one of them (it's id, actually)

作为视图模型:

public class CashbackOfferViewModel
{
    ...
    public string DepositBank { get; set; }
    public IEnumerable<CompanyBank> DepositBanks { get; set; } 
}

我想使用类似的东西:

@Html.EditorFor(m => m.DepositBanks)

这将创建适当的单选按钮.但是在创建编辑器模板时，如果我使用模型

and that would create the appropriate radio buttons. But when creating the editor template if I use the model

@model CompanyBank

@Html.RadioButtonFor(??????)
@Html.LabelFor(????)

如何将其绑定到模型中的 DepositBank 属性?

How do I bind it to the DepositBank property in the model??

更新:

我一直在努力做到这一点，但目前的情况

I've been trying to make this work but with the current situation

视图模型:

public class CashbackOfferViewModel
{
    ....
    public string DepositBankCode { get; set; }
    public IEnumerable<CompanyBank> DepositBanks { get; set; } 
}

编辑器模板；

@model CompanyBank

<tr>
  <td>
      @Html.RadioButtonFor(m => m.CompanyBankCode, Model.CompanyBankCode)
      <span>@Html.LabelFor(m => m.CompanyBankName, Model.CompanyBankName)</span>
  </td>
</tr>

但我在加载时检查了所有单选按钮，实际上生成的 html 就是这个(更改每个按钮的 id)

But I'm getting all the radio buttons checked on load, actually the html generated is this one (changing the id for each of them)

<input checked="checked" id="DepositBanks_0__CompanyBankCode" name="DepositBanks[0].CompanyBankCode" type="radio" value="HBOS">

基本上我想在视图中使用它:

Basically I would like to use this in the view:

@Html.EditorFor(m => m.DepositBanks)

而不是这个

@foreach (var depositBank in Model.DepositBanks)
{
    @Html.RadioButtonFor(m => m.DepositBankCode , depositBank.CompanyBankCode)
}

推荐答案

你只需要引用你要绑定的属性名

you just need to reference the property names you want to bind

@model CompanyBank


@Html.RadioButtonFor(x => x.PropertyName)
@Html.LabelFor(x => x.PropertyName)

确保您将视图命名为 CompanyBank.cshtml，因为在 IEnumerable 中您无法定义编辑器视图名称.

make sure that you name your view CompanyBank.cshtml because in IEnumerable you cannot define the editor view name.
