Asp.net mvc 3 将ModelMetaData复制到子属性'；模型元数据

我创建了一个包装器模型，其中包含一个内部属性Value，它是要在视图中显示的属性。在最外层的模型中，我创建了一个包装器类型的属性，并对该属性应用了一些属性和验证。在呈现包装器视图时，我希望将所有验证和属性从包装器复制到内部值属性，以便在最后调用

EditorFor（m=>m.Value）

时，呈现子属性的视图也呈现与容器属性相关的验证器等

HomeController.cs

namespace MvcApplication1.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View(new IndexModel());
        }
    }
}

namespace MvcApplication1.Models.Home
{
    public class IndexModel
    {
        [Display(Name = "Test Edit Field")]
        [MaxLength(10)]
        [AdditionalMetadata("ViewName", "String")]
        [TemplateVisibility(false, true)]
        public BatchEditField<string> TestEditField { get; set; }

        public IndexModel()
        {
            this.TestEditField = new BatchEditField<string>("TEST");
        }
    }
}

IndexModel.cs

namespace MvcApplication1.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View(new IndexModel());
        }
    }
}

namespace MvcApplication1.Models.Home
{
    public class IndexModel
    {
        [Display(Name = "Test Edit Field")]
        [MaxLength(10)]
        [AdditionalMetadata("ViewName", "String")]
        [TemplateVisibility(false, true)]
        public BatchEditField<string> TestEditField { get; set; }

        public IndexModel()
        {
            this.TestEditField = new BatchEditField<string>("TEST");
        }
    }
}

摘要

最后，在呈现页面时，不包括任何验证元素等，因为在呈现String.cshtml时，它们不存在于ModelMetaData中

@* Inspecting this.ViewData.ModelMetaData.AdditionalValues shows that it is empty; the parent AdditionalValues that were copied in the wrapper view did not make it through. *@
@Html.TextBox(string.Empty, this.ViewData.TemplateInfo.FormattedModelValue)
@Html.ValidationMessage(string.Empty)
