This article is mainly for everyone to introduce the MVC5 drop-down box binding, with a certain reference value, interested in small partners can refer to

The example of this article for everyone to share the MVC5 drop-down box single-select binding code, for your reference, the specific content as follows

1.Model

[Display (Name = "education")] public icollection<system.web.mvc.selectlistitem> asdflist{get; set;}  Type of drop-down box [Display (Name = "education")][required]public int asdf {get; set;}    Education the properties of this field

2.controller

(1) First write a program binding, either through the database binding or directly bound

[Description ("Education")] [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 is a helper class that has been written to facilitate the operation of the database     var factoroptions = dt. AsEnumerable (). Select (row = new SelectListItem      {        Text = row["Name"],        Value = row["id"]      }). ToList ();      return factoroptions;} [Description ("Education")] [Loginallowview]private list<selectlistitem> bind_education () {    list<selectlistitem> ListItem = new List<selectlistitem> ();    Listitem.add (new SelectListItem {Text = "undergraduate", Value = "1"});    Listitem.add (new SelectListItem {Text = "master", Value = "2"});     Listitem.add (new SelectListItem {Text = "Doctor", Value = "3"});     return listItem; }

(2) Initialize and pass to view

[Description ("My Qualifications")] [Uiexceptionresult] public ActionResult Edu () {    var edu= new Edumodel ();    Edu.asdflist=bind_education ();  Initializes the value of the drop-down box to    return View (EDU);

3. View

@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 is the bootstrap style, JS added: $ ('. Select2 '). Select2 ();
