    </div>

    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">

            <p id="content"></p>
        </div>
    </div>

</form>

这是模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

public class BrandViewModels
    {

        [Display(Name = "Brand Code")]
        [Required(ErrorMessage = "Brand Code is required")]
        [RegularExpression(@"(\S)+", ErrorMessage = "White space is not allowed.")]
        [Remote("IsUniqueBrandCode", "Product", AdditionalFields = "BrandCode", HttpMethod = "POST", ErrorMessage = "Brand Code already exists.")]
        public string BrandCode { get; set; }
        public int CompanyId { get; set; }
        public List<ProductSubGroupList> ProductSubGroupList { get; set; }
        public List<ProductGroupList> ProductGroupList { get; set; }

        [Required(ErrorMessage = "Please select product group")]
        [Display(Name = "Product Group")]
        public string ProductGroupCode { get; set; }


        [Required(ErrorMessage = "Please select product sub group")]
        [Display(Name = "Product Sub Group")]
        public string ProductSubGroupCode { get; set; }

        [Required(ErrorMessage = "Brand name is required")]
        [Display(Name = "Brand Name")]
        public string BrandName { get; set; }

        [Required(ErrorMessage = "Description is required")]
        [Display(Name = "Description")]
        public string BrandDescription { get; set; }

        [Display(Name = "Active")]
        public bool Active { get; set; }

        [Display(Name = "Sort Order")]
        [Required(ErrorMessage = "Sorting order is required")]
        public int? SortOrder { get; set; }

    }

Answer 1

请检查您是否在Web Config中有以下Appsettings

<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />

请参阅Data Anotation validation

Answer 2

这是我的代码工作完美我看到你的代码你可能有这些错误，

您应该使用@using (Html.BeginForm())代替<form>

@Html.ValidationSummary(false)代替@Html.ValidationSummary(true) 请看我的代码。

           <div class="container">
            @using (Html.BeginForm())
            {
                @Html.AntiForgeryToken()

                <div class="form-horizontal">
                    <h4>mymodel</h4>
                    <hr />
                    @Html.ValidationSummary(false)

                    <div class="form-group">
                        @Html.LabelFor(model => model.id, new { @class = "control-label col-md-2" })
                        <div class="col-md-10">
                            @Html.EditorFor(model => model.id)
                            @Html.ValidationMessageFor(model => model.id)
                        </div>
                    </div>
                    <div class="form-group">
                        @Html.LabelFor(model => model.name, new { @class = "control-label col-md-2" })
                        <div class="col-md-10">
                            @Html.EditorFor(model => model.name)
                            @Html.ValidationMessageFor(model => model.name)
                        </div>
                    </div>

                    <div class="form-group">
                        <div class="col-md-offset-2 col-md-10">
                            <input type="submit" value="Create" class="btn btn-default" />
                        </div>
                    </div>
                </div>
            }
        </div>
        <div>
            @Html.ActionLink("Back to List", "Index")
        </div>
        <script src="~/Scripts/jquery-1.10.2.min.js"></script>
        <script src="~/Scripts/jquery.validate.min.js"></script>
        <script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>
