asp.net-mvc - DataAnnotations.DisplayAttribute.Order 属性是否不适用于 ASP.NET MVC 2？

Question

我为 Order property 设置了值的 Display attribute在我的模型元数据中。

[MetadataType(typeof(OccasionMetadata))]
public partial class Occasion
{
    private class OccasionMetadata
    {
        [ScaffoldColumn(false)]
        public object Id { get; set; }

        [Required]
        [Display(Name = "Title", Order = 0)]
        public object Designation { get; set; }

        [Required]
        [DataType(DataType.MultilineText)]
        [Display(Order = 3)]
        public object Summary { get; set; }

        [Required]
        [DataType(DataType.DateTime)]
        [Display(Order = 1)]
        public object Start { get; set; }

        [Required]
        [DataType(DataType.DateTime)]
        [Display(Order = 2)]
        public object Finish { get; set; }
    }
}

我使用 DisplayForModel 在强类型 View 中展示我的模型和 EditorForModel方法。

<%= Html.DisplayForModel() %>

和

<%= Html.EditorForModel() %>

但是，ASP.NET MVC 2 显示的字段是乱序的!我可能有什么问题？

.NET 4 DataAnnotations comes with a new Display attribute that has several properties including specifying the value that is used for display in the UI and a ResourceType. Unfortunately, this attribute is new and is not supported in MVC 2 RTM.

The good news is it will be supported and is currently available in the MVC Futures release.

The steps to get this working are shown below...
