MVC5下拉框单选绑定的具体代码实现

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 ICollectionSystem.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 ListSelectListItem>
 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 ListSelectListItem>
 bind_Education(){
        ListSelectListItem>
     listItem = new ListSelectListItem>
    ();
    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  p class="form-group">
        @HtML.LabelFor(m =>
 m.agj03, new {
 @class = "col-sm-2 control-label" }
    )        p 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" }
    )        /p>
     /p>
    

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