Custom User Registration form in entity framework code first and asp.net mvc example

In this tutorial I am going to demonstrate to create registration form using entity framework code first approach in asp.net MVC.In this demonstration I also implement cascade drop-downs(Country and state).

Database Tables:

Country

Employee

State

In this example I am using three tables , employees state and country. state and country tables are used for cascade dropdown and employee table is used to save employee data.

Let’s start

Create a new Project. Open Visual Studio 2013.
Go to “File” => “New” => “Project…”.
Select “Web” in installed templates.
Select “ASP.NET MVC Web Application”.
Enter the Name and choose the location.
Click “OK”.

Following is the database script of country , state and employees.

CREATE TABLE [dbo].[country](

       [country_id] [int] IDENTITY(1,1) NOT NULL,

       [country_name] [varchar](50) NOT NULL,

       [country_abbrev] [varchar](3) NOT NULL,

PRIMARY KEY CLUSTERED

(

       [country_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

 

SET ANSI_PADDING OFF

GO

CREATE TABLE [dbo].[state](

       [state_id] [int] IDENTITY(1,1) NOT NULL,

       [country_id] [int] NULL,

       [state_name] [varchar](50) NOT NULL,

       [state_abbrev] [varchar](2) NOT NULL,

 CONSTRAINT [PK__state__81A47417FDC731AD] PRIMARY KEY CLUSTERED

(

       [state_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

 

SET ANSI_PADDING OFF

GO

 

ALTER TABLE [dbo].[state]  WITH CHECK ADD  CONSTRAINT [FK_state_country] FOREIGN KEY([country_id])

REFERENCES [dbo].[country] ([country_id])

GO

&nbsp;
CREATE TABLE [dbo].[Employee](
	[empid] [int] IDENTITY(1,1) NOT NULL,
	[empname] [varchar](50) NULL,
	[empfathername] [varchar](50) NULL,
	[empsalary] [int] NULL,
	[country_name] [varchar](50) NULL,
	[state_name] [varchar](50) NULL,
	[email] [varchar](50) NULL,
	[accountactivated] [bit] NULL,
 CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED 
(
	[empid] 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

SET ANSI_PADDING OFF
GO

now first we create models for country ,state and employee.

we will create 3 classes in models folder.

ASP.NET Core 2.0 Online Training

Employee

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Web;

namespace EF.Models
{
    [Table("Employee")]
    public class Employee
    {
        [Key]
        public int empid { get; set; }
        public string empname { get; set; }
        public string empfathername { get; set; }
        public int empsalary { get; set; }
        public string country_name { get; set; }
        public string state_name { get; set; }
        public string email { get; set; }
        public bool? accountactivated { get; set; }
      

    }
   
}

Country

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Web;

namespace EF.Models
{
    [Table("Country")]
    public class Country
    {
        [Key]
        public int country_id { get; set; }
        public string country_name { get; set; }
    }
}

State

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Web;

namespace EF.Models
{
    [Table("State")]
    public class State
    {
   
        public int country_id { get; set; }
 [Key]
        public int state_id { get; set; }
        public string state_name { get; set; }
    }
}

to implement Insert operations in database Table Employee using entity framework code first .we have to define data context class which will inherit the DbContext.

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;


namespace EF.Models
{
    public class DataContext :DbContext
    {
        public DataContext() : base("conn") { }
        public DbSet<Employee> Employees { get; set; }
        public DbSet<Country> Countries { get; set; }
        public DbSet<State> States { get; set; }
    }
}

define database connection string in web.config file.

<connectionStrings>

    <add name="conn" connectionString="server=JOHN\YOGESHDOTNET;database=ganesha;integrated security=SSPI" providerName="System.Data.SqlClient"/>
    
  </connectionStrings>

Home Controller

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using EF.Models;

namespace EF.Controllers
{
    public class HomeController : Controller
    {
        private DataContext db = new DataContext();
        static string Cname = "";
        // GET: /Home/
        public ActionResult Index()
        {
            return View(db.Employees.ToList());
        }

        // GET: /Home/Details/5
        public ActionResult Details(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Employee employee = db.Employees.Find(id);
            if (employee == null)
            {
                return HttpNotFound();
            }
            return View(employee);
        }

        // GET: /Home/Create
        public ActionResult Create()
        {
            ViewBag.Countries = db.Countries.ToList();
            return View();
        }
        private IList<State> GetState(int Countryid)
        {
            var data = db.States.Where(m => m.country_id == Countryid).ToList();
               
            return data;

        }

        [AcceptVerbs(HttpVerbs.Get)]

        public JsonResult LoadStatesByCountryId(string Countryid, string cn)
        {
            Cname = cn;
            var StateList = this.GetState(Convert.ToInt32(Countryid));

            var StatesData = StateList.Select(m => new SelectListItem()

            {

                Text = m.state_name,

                Value = m.state_id.ToString(),

            });

            return Json(StatesData, JsonRequestBehavior.AllowGet);

        }


       
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create([Bind(Include="empid,empname,empfathername,empsalary,country_name,state_name,email")] Employee employee, FormCollection frm)
        {
            if (ModelState.IsValid)
            {
                Employee em = new Employee();
                em.country_name = Cname;
                int sname =Convert.ToInt16(frm["state_name"]);
                em.state_name = db.States.Single(x => x.state_id == sname).state_name;
               // em.state_name = frm["state_name"];
                em.empname = frm["empname"];
                em.empfathername = frm["empfathername"];
                em.empsalary =Convert.ToInt32(frm["empsalary"]);
                em.email = frm["email"];
                
                db.Employees.Add(em);

                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(employee);
        }

    
       

      

        protected override void Dispose(bool disposing)
        {
