Dropdown with Multiple checkbox select with jQuery in MVC 5

In this article I will explain how to implement a Multiple Select (MultiSelect) DropDownList with CheckBoxes in ASP.Net with jQuery Bootstrap Multi-Select Plugin.

So as to actualize a Multiple Select (MultiSelect) DropDownList with CheckBoxes in ASP.Net we should make use of ListBox control and apply the jQuery Bootstrap Multi-Select Plugin to it.

 You can follow these simple steps to implement a Multiple Select DropdownList with CheckBox. 

I am creating a MVC application and create controller "Home"

In next step create Action to open view "Index" see example.

1. using System;  
2. using System.Collections.Generic;  
3. using System.Linq;  
4. using System.Web;  
5. using System.Web.Mvc;  
6.   
7. namespace DropdownCheckbox.Controllers  
8. {  
9.     public class HomeController : Controller  
10.     {  
11.         public ActionResult Index()  
12.         {  
13.             return View();  
14.         }  
15.   
16.          
17.     }  
18. }  

Create view name as "Index".see example.

1. @{  
2.     ViewBag.Title = "Home Page";  
3.     Layout = null;  
4. }  
5.   
6. <div>  
7.   <table>  
8.       <tr>  
9.           <td><p >Select Expert's Name  </p></td>  
10.           <td>  
11.     <select id="EmpList" multiple="multiple">  
12.     <option value="1">Navdeep-Asp.net</option>  
13.     <option value="2">Pankaj-C#</option>  
14.     <option value="3">Bikesh-Asp.Net</option>  
15.     <option value="4">Pritam-Salesforce</option>  
16.     <option value="5">Payal-Salesforce</option>  
17.     <option value="6">Sujata-SSRS</option>  
18.     <option value="7">Harikant-UI</option>  
19.   
20. </select>  
21.           </td>  
22.           <td><input type="button" id="btnSelected" value="Get Selected" /></td>  
23.       </tr>  
24.   </table>  
25.      
26.       
27. </div>  

In this article i am using hard code value,but you can bind from database .after that add jquery plugins or CDN.like this.

1. <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>  
2.  <link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.3/css/bootstrap.min.css"  
3.        rel="stylesheet" type="text/css" />  
4.  <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.3/js/bootstrap.min.js"></script>  
5.  <link href="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/css/bootstrap-multiselect.css"  
6.        rel="stylesheet" type="text/css" />  
7.  <script src="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/js/bootstrap-multiselect.js"  
8.          type="text/javascript"></script>  

 Use these references in your application .

 After that write js code to implement multiselect with checkbox in dropdown.use this code.

1. <script type="text/javascript">  
2.         $(function () {  
3.             $('#EmpList').multiselect({  
4.                 includeSelectAllOption: true  
5.             });  
6.             $('#btnSelected').click(function () {  
7.                 var selected = $("#EmpList option:selected");  
8.                 var message = "";  
9.                 selected.each(function () {  
10.                     message += $(this).text() + " " + $(this).val() + "\n";  
11.                 });  
12.                 alert(message);  
13.             });  
14.         });  
15.     </script>  

Set routing inside "route.config" file.see code.

1. using System;  
2. using System.Collections.Generic;  
3. using System.Linq;  
4. using System.Web;  
5. using System.Web.Mvc;  
6. using System.Web.Routing;  
7.   
8. namespace DropdownCheckbox  
9. {  
10.     public class RouteConfig  
11.     {  
12.         public static void RegisterRoutes(RouteCollection routes)  
13.         {  
14.             routes.IgnoreRoute("{resource}.axd/{*pathInfo}");  
15.   
16.             routes.MapRoute(  
17.                 name: "Default",  
18.                 url: "{controller}/{action}/{id}",  
19.                 defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }  
20.             );  
21.         }  
22.     }  
23. }  

 Complete code 

 You can see and understand complete code.

1. @{  
2.     ViewBag.Title = "Home Page";  
3.     Layout = null;  
4. }  
5.   
6.     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>  
7.     <link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.3/css/bootstrap.min.css"  
8.           rel="stylesheet" type="text/css" />  
9.     <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.3/js/bootstrap.min.js"></script>  
10.     <link href="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/css/bootstrap-multiselect.css"  
11.           rel="stylesheet" type="text/css" />  
12.     <script src="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/js/bootstrap-multiselect.js"  
13.             type="text/javascript"></script>  
14.     <script type="text/javascript">  
15.         $(function () {  
16.             $('#EmpList').multiselect({  
17.                 includeSelectAllOption: true  
18.             });  
19.             $('#btnSelected').click(function () {  
20.                 var selected = $("#EmpList option:selected");  
21.                 var message = "";  
22.                 selected.each(function () {  
23.                     message += $(this).text() + " " + $(this).val() + "\n";  
24.                 });  
25.                 alert(message);  
26.             });  
27.         });  
28.     </script>  
29. <div>  
30.   <table>  
31.       <tr>  
32.           <td><p >Select Expert's Name  </p></td>  
33.           <td>  
34.     <select id="EmpList" multiple="multiple">  
35.     <option value="1">Navdeep-Asp.net</option>  
36.     <option value="2">Pankaj-C#</option>  
37.     <option value="3">Bikesh-Asp.Net</option>  
38.     <option value="4">Pritam-Salesforce</option>  
39.     <option value="5">Payal-Salesforce</option>  
40.     <option value="6">Sujata-SSRS</option>  
41.     <option value="7">Harikant-UI</option>  
42.   
43. </select>  
44.           </td>  
45.           <td><input type="button" id="btnSelected" value="Get Selected" /></td>  
46.       </tr>  
47.   </table>
