[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 |

[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

@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();
