In the view I have a lot of RadioButtons and the id is the unique for each one. when user choose one of those in controller I would like to take the ID and VALUE how i can do that.... i try with formCollection but in here i just can take value...

和问题是我怎么可以通过控制POST操作中的ID和价值。

and the question is how can I take the ID and VALUE by 'POST' Action in the control.

推荐答案

我建议你使用的视图模型。请波纹管看到这样的例子：

I suggest you to use view model. Please see this example bellow:

namespace MvcApplication1.Controllers {

    public class TheOption {
        public string Id { get; set; }
        public string Value { get; set; }
        public bool? Checked { get; set; }
    }

    public class FooController : Controller {
        //
        // GET: /Foo/

        public ActionResult Index() {
            var options = new List<TheOption> {
                new TheOption {Id = "One", Value = "The One"},
                new TheOption {Id = "Two", Value = "The Two"},
                new TheOption {Id = "Hundred", Value = "The Hundred"},
            };
            return View(options);
        }

        [HttpPost]
        public ActionResult Index(List<TheOption> options) {
            return View(options);
        }

    }
}

现在你需要创建 TheOption 模型编辑器模板。它只是由下创建名为〜 EditorTemplates \\浏览\\共享\\文件夹中的文件夹。添加新视图编辑器模板。命名此编辑模板，以配合型号名称（ TheOption ）。

Now you need to create editor template for TheOption model. It's simply by create folder named EditorTemplates under ~\Views\Shared\ folder. Add new view as the editor template. Name this editor template to match with the model name (TheOption).

下面是内容的〜\\查看\\共享\\ EditorTemplates \\ TheOption.cshtml

@model MvcApplication1.Controllers.TheOption
<div>
    @Html.RadioButtonFor(m => m.Checked, true, new { id = Model.Id + "_selected" })
    @Html.RadioButtonFor(m => m.Checked, false, new { id = Model.Id }) @Model.Value

    @Html.HiddenFor(m => m.Id)
    @Html.HiddenFor(m => m.Value)
</div>

现在去你的主视图（Index.cshtml），简单地把这个code：

Now go to your main view (Index.cshtml) and simply put this code:

@model System.Collections.Generic.List<MvcApplication1.Controllers.TheOption>
@using (Html.BeginForm()) {
    @Html.EditorFor(m=>m)    
    <button type="submit">Save</button>
}

完成！希望这有助于：）

Done! Hope this helps :)
