How To Bind Checkbox From Database In MVC 5 Using Entity Framework

Introduction

In this article I will demonstrate how to bind checkbox from database table in MVC5 using Entity Framework. I will also show selected checkbox value after button submit.

Step 1

Open SQL Server 2014 and create database table to insert data and retrieve data.

CREATE TABLE [dbo].[Languages](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Programming_Language] [nvarchar](50) NULL,
CONSTRAINT [PK_Languages] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

Following class will be added:

namespace MvcCheckBoxList_Demo.Models
{
using System;
using System.Collections.Generic;
public partial class Language
{
public int ID { get; set; }
public string Programming_Language { get; set; }
public bool IsCheked { get; set; }
}
public class LanguageModel
{
public List<Language> Languages { get; set; }
}
}

Step 4

Right click on Controllers folder select Add then choose Controller as shown in below screenshot.

After clicking on controller a window will appear, choose MVC5 Controller-Empty click on Add.

After clicking on Add another window will appear with DefaultController. Change the name HomeController then click on Add. HomeController will be added under Controllers folder. Remember don’t change the suffix for all controllers, change only highlighted one, and instead of Default just change Home. As showm in below screenshot.

ASP.NET

Add the following namespace in controller

using MvcCheckBoxList_Demo.Models;

Complete controller code

using MvcCheckBoxList_Demo.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MvcCheckBoxList_Demo.Controllers
{
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
LanguageModel ProgrammingLanguage = new LanguageModel();
using (DBModel db = new DBModel())
{
ProgrammingLanguage.Languages = db.Languages.ToList<Language>();
}
return View(ProgrammingLanguage);
}
[HttpPost]
public ActionResult Index(LanguageModel model)
{
var selectedLanguage = model.Languages.Where(x => x.IsCheked == true).ToList<Language>();
return Content(String.Join(",", selectedLanguage.Select(x => x.Programming_Language)));
}
}
}

Step 5

Right click on index action method in controller. Add view, a window will appear with default index name unchecked (use a Layout page) and click on Add as show in below screenshot. View will be added in views folder under Home folder with name index.

Step 6

Click on Tools, select NuGet Package Manager, then choose Manage NuGet Packages for Solution and click on it.

ASP.NET

Similarly type JQuery and install latest version of JQuery package in project and Jquery validation file from NuGet then close NuGet Solution.

Keep required bootstrap and jQuery files and delete remaining files if you're not using them.

Step 7

Write the following code in index view.

Complete view code

@model MvcCheckBoxList_Demo.Models.LanguageModel
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<link href="~/Content/bootstrap.min.css" rel="stylesheet" />
<script src="~/scripts/jquery-3.3.1.min.js"></script>
<script src="~/scripts/bootstrap.min.js"></script>
</head>
<body>
<div class="container py-4">
<h5 class="text-center text-uppercase">How to bind checkbox in mvc5 from database</h5>
@using (Html.BeginForm())
{
<table>
@for (int i = 0; i < Model.Languages.Count; i++)
{
if (i % 4 == 0)
{
@:
<tr></tr>
}
<td>
@Html.CheckBoxFor(x => x.Languages[i].IsCheked, new { @class = "custom-checkbox" })
<label>@Model.Languages[i].Programming_Language</label>
@Html.HiddenFor(x => x.Languages[i].ID)
@Html.HiddenFor(x => x.Languages[i].Programming_Language)
</td>
}
</table>
<input type="submit" class="btn btn-outline-primary rounded-0" value="Submit" />
}
</div>
</body>
