MVC5下拉框绑定的方法（单选）

本文实例为大家分享了MVC5下拉框单选绑定的具体代码，供大家参考，具体内容如下

1.Model

[Display(Name = "学历")] public ICollection<System.Web.Mvc.SelectListItem> asdflist{ get; set; }  //下拉框的类型[Display(Name = "学历")][Required]public int asdf { get; set; }    //学历这个字段的属性

2.controller

(1)先写一个程式绑定,可以通过数据库绑定或者直接绑定

[Description("学历")][LoginAllowView] private List<SelectListItem> bind_Education(){     StringBuilder sb = new StringBuilder();     sb.Append(" select id,name ");     sb.Append(" from Edu_file ");     DataTable dt = sqlHelp.getData(sb.ToString());//sqlHelp是已经写好的帮助类,便于数据库的操作     var factorOptions = dt.AsEnumerable().Select(row => new SelectListItem      {        Text = row["name"],        Value = row["id"]      }).ToList();      return factorOptions;}[Description("学历")][LoginAllowView]private List<SelectListItem> bind_Education(){    List<SelectListItem> listItem = new List<SelectListItem>();    listItem.Add(new SelectListItem { Text = "本科", Value = "1" });    listItem.Add(new SelectListItem { Text = "硕士", Value = "2" });     listItem.Add(new SelectListItem { Text = "博士", Value = "3" });     return listItem; }

(2)初始化,并传给视图

[Description("我的学历")][UIExceptionResult] public ActionResult Edu(){    var edu= new EduModel();    edu.asdflist=bind_Education();  //初始化下拉框的值    return View(edu); }

3.视图

@model RsJob.Web.Models.EduModel  <div class="form-group">    @Html.LabelFor(m => m.agj03, new { @class = "col-sm-2 control-label" })        <div class="col-sm-10">          @Html.DropDownListFor(model => model.asdf, Model.asdflist, new { @class = "form-control select2", style = "width: 100%;" })          @Html.ValidationMessageFor(m => m.asdf, "", new { @class = "text-danger" })        </div> </div>

select2是bootstrap的样式,js添加:$('.select2').select2();
