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();
