Asp.net mvc 创建@Html.RadioButtonFor（ASP.NET MVC4）

这是任务模式

namespace TaskManager.Models
{
    public class Task
    {
        private const int DefaultTaskPriority = 1;

        //some other properties

        [DefaultValue(DefaultTaskPriority)]
        public TaskPriority Priority { get; set; }

    }

    public enum TaskPriority
    {
        [Display(Name = "Low")]
        Low = 0,

        [Display(Name = "Default")]
        Normal = 1,

        [Display(Name = "High")]
        High = 2,

        [Display(Name = "Extreme")]
        Extreme = 3
    }
}

这是我观点的一部分

<div class="form-group">
@Html.LabelFor(u => u.Priority)
<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, 0) Low</label>
</div>

<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, 1, new { Checked = "checked" }) Default</label>
</div>

<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, 2) High</label>
</div>

<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, 3) Extreme</label>
</div>
@Html.ValidationMessageFor(u => u.Description, null, new {@class = "error"})                    
</div>

您不应该设置

new{Checked=“Checked”}

-它是

优先级的值，它将决定选择什么（这就是模型绑定的工作原理。您还可以将int值替换为
TaskPriority.Low
，
TaskPriority.Normal
等。如果我没有设置
new{Checked=“Checked”}，您可以始终创建一个扩展方法来获取显示名称
未选择此单选按钮，我希望用户查看默认情况下选择的选项。错误。如果
优先级的值为
TaskPriority.Normal
，则将选择第二个（如果未明确设置，则默认为
TaskPriority.Low
）。不要试图覆盖MVC的模型绑定功能。另一个建议是添加
new{id=''}
以删除每个单选按钮中重复的
id
属性，并且
@Html.LabelFor（u=>u.Priority）
有点毫无意义（您已经有了与每个按钮关联的标签）所以它应该是
@Html.DisplayNameFor（m=>m.Priority）
<div class="form-group">
@Html.LabelFor(u => u.Priority)
<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, TaskPriority.Low) Low</label>
</div>

<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, TaskPriority.Normal) Normal</label>
</div>

<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, TaskPriority.High) High</label>
</div>

<div class="radio">
    <label>@Html.RadioButtonFor(model => model.Priority, TaskPriority.Extreme) Extreme</label>
</div>
@Html.ValidationMessageFor(u => u.Description, null, new {@class = "error"})                    
</div>
