我去  博客园 咋不支持 上传图片了啊

 <div class="rule-single-select" id="typeIdClick">
                    @Html.DropDownList("TypeId", listProductTypes, new
               {
                   datatype=@"/^[1-9]+$/",
                   sucmsg=" ",
                   nullmsg="请选择商品分类",
                   errormsg="请选择商品分类"
               })
                </div>

@IT小伙儿: 让你上代码，不是上界面，另外一个代码呢？

@顾晓北:  [DisplayName("商品分类")]
        [Range(1, int.MaxValue, ErrorMessage = "请选择商品分类")]
        public int TypeId { get; set; }

        [DisplayName("商品分类")]
        public ProductTypeModel ProductType { get; set; }


        [DisplayName("商品渠道")]
        [Range(1, int.MaxValue, ErrorMessage = "请选择商品渠道")]
        public int ChannelId { get; set; }

        [DisplayName("商品渠道")]
        public ChannelModel Channel { get; set; }
