Question

我有一个模型如下

public partial class Approval
{
    public bool IsApproved { get; set; }
}

在视图中渲染模型时，我正在使用用于IsApproved属性的无线电按钮

@Html.RadioButtonFor(model => model.IsApproved, "Yes", htmlAttributes: new { @id = "Approve"})
@Html.Label("Yes", htmlAttributes: new { @style = "padding-right:10px;vertical-align:top" })
@Html.RadioButtonFor(model => model.IsApproved, "No", htmlAttributes: new { @id = "Reject", })
@Html.Label("No", htmlAttributes: new { @style = "padding-right:10px;vertical-align:top" })

提交时，我得到ModelState.IsValid为false，因为IsApproved的类型为bool，我在View中传递字符串

如果我更改单选按钮

@Html.RadioButtonFor(model => model.IsApproved, Model.IsApproved, htmlAttributes: new { @id = "Approve"})
@Html.RadioButtonFor(model => model.IsApproved, !Model.IsApproved, htmlAttributes: new { @id = "Reject", })

默认情况下，单选按钮会在我不想要的页面加载中进行检查。

建议正确的方法

控制器：

public ActionResult Index()
{
    return View(Approval)
    {
        IsApproved = true;
    });
}

[HttpPost]
public ActionResult Index(Approval Approvalmodel)
{
    return Content("IsApproved: " + Approvalmodel.IsApproved);
}

查看：

@model Approval

@using (Html.BeginForm())
{
 @Html.RadioButtonFor(model => model.IsApproved, "true", new { id = "Approved" }) 
 @Html.Label("Yes", htmlAttributes: new { @style = "padding-right:10px;vertical-align:top" })
 @Html.RadioButtonFor(model => model.IsApproved, "false", new { id = "Rejected" }) 
 @Html.Label("No", htmlAttributes: new { @style = "padding-right:10px;vertical-align:top" })
    <button type="submit">OK</button>
}

默认情况下，在MVC中为Bool属性选择单选按钮
