获取控制器MVC 4复选框值 [英] Get checkbox values in controller mvc 4

问题描述

我尝试从一个复选框列表中选中的复选框值没有任何成功，下面是code，我曾尝试：

I am trying to retrieve the checked checkbox value from a checkbox list without any success , below is the code which i have tried:

示范

 [DisplayName("Gender")]
    public IList<SelectListItem> Gender { get; set; }

控制器

 public ActionResult Index()
        {
            AssociateFormViewModel objStudentModel = new AssociateFormViewModel();

            List<SelectListItem> genderNames = new List<SelectListItem>();
            genderNames.Add(new SelectListItem { Text = "Male", Value = "1" });
            genderNames.Add(new SelectListItem { Text = "Female", Value = "2" });
            genderNames.Add(new SelectListItem { Text = "Prefer not to say", Value = "3" });

            objStudentModel.Gender = genderNames;
            return PartialView("AssociateApplicationForm", objStudentModel);

        }

[HttpPost]
        public ActionResult HandleFormSubmit(MembershipFormViewModel model)
        {
            //model not valid, do not save, but return current umbraco page
            if (ModelState.IsValid == false)
            {
                return CurrentUmbracoPage();
            }
 string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here
 return RedirectToCurrentUmbracoPage();
}

查看

@foreach (var names in @Model.Gender)
                {
                var checkBoxId = "chk" + names.Value;
                var tdId = "td" + names.Value;
                    <table width="100%">
                        <tr >
                            <td width="20px">
                                <input type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" />
                            </td>
                            <td id="@tdId"  width="100px">
                                @names.Text
                            </td>
                        </tr>
                    </table>

}

在任何地方我得到的想法是错误的选中的复选框值在行动后未来空，又怎么能我限制用户只选择一个复选框，

Any ideas where i am getting it wrong the selected checkbox value is coming null in the post action, Also how can i limit the user to select only one check box,

任何帮助或建议将AP preciated。
谢谢

Any help or suggestion will be appreciated . Thanks

推荐答案

分配一个名称，你的复选框：

assign a name to your checkbox:

<input name="gender" type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" />

然后接受与参数名称的字符串数组性别

[HttpPost]
        public ActionResult HandleFormSubmit(string[] gender,
             MembershipFormViewModel model)
        {
            //model not valid, do not save, but return current umbraco page
            if (ModelState.IsValid == false)
            {
                return CurrentUmbracoPage();
            }
            string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here
            return RedirectToCurrentUmbracoPage();
        }
