First we create database and table

Countrylist table for first dropdown

CREATE TABLE [dbo].[Country](
          [Id] [int] IDENTITY(1,1) primary key NOT NULL,
          [Country] [varchar](50) NULL,
          )

DistrictList table

CREATE TABLE [dbo].[District](
          [Id] [int] IDENTITY(1,1) primary key NOT NULL,
          [District] [varchar](50) NULL,
          )

And Statelist table

CREATE TABLE [dbo].[State](
          [Id] [int] IDENTITY(1,1) primary key NOT NULL,
          [State] [varchar](50) NULL,
          )

And Registrationform table

 
CREATE TABLE [dbo].[Registration](
          [Id] [int] IDENTITY(1,1) primary key NOT NULL,
          [Name] [varchar](50) NULL,
          [Country] [varchar](50) NULL,
          [State] [varchar](50) NULL,
          [District] [varchar](50) NULL,
          [Address] [varchar](50) NULL,
)

Now add New Project and Right Click on the Models folder and select Ado.Net Entity Data Model

And the click generate From Database

And next and then give connection information and select your database.

Then choose tables and then finish.

In the next step we will create Home Controller for adding controller right click on the controllers folder and go to add and then click controller then a pop up will be appear from here you can change you can give your controller name .

In the controller copy the following code.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Data;
using MvcApplication4.Models;
 
namespace MvcApplication4.Controllers
{
   
public class HomeController : Controller
   
{
       
//
       
// GET: /Home/
 
       
public ActionResult Index()
       
{
            var
context = new DropdownEntities();
            ViewBag.country = context.Countries;
            ViewBag.state = context.States;
            ViewBag.district =
context.Districts;
            return View();
            
       
}
       
[HttpPost]
       
public ActionResult Add(Registration Model)
       
{
            using(var context=new DropdownEntities())
            {
               
context.Registrations.Add(Model);
                context.SaveChanges();
            }
            var
context1 = new DropdownEntities();
            ViewBag.country =
context1.Countries;
            ViewBag.state = context1.States;
            ViewBag.district =
context1.Districts;
            return View("Index");
       
}
 
   
}
}

And in the view

 
@model MvcApplication4.Models.Registration
@{
   
Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
   
<meta name="viewport" content="width=device-width" />
   
<title>Index</title>
   
<style>
       
select {
       
width:200px}
       
input {
       
width:200px}
            input[type="Submit"] {
                color:blue;
                width:80px;
            }
       
fieldset {
            width:500px;
            margin-left:250px;
       
}
   
</style>
</head>
<body>
   
<div>
      
@using (Html.BeginForm("Add","Home",FormMethod.Post))
      
{
            
          
<fieldset>
               <legend><strong>Registration Form</strong></legend>
          
<table>
               <tr><td>
                   Name:
                  @Html.TextBoxFor(x=>x.Name)</td>
                   <td>Country:@Html.DropDownListFor(x =>
x.Country, new SelectList(ViewBag.country,"country1","country1"),"Select")</td>
                   </tr>
               <tr>
                   <td>
                     State:<br />
                       @Html.DropDownListFor(x=>x.State,new SelectList(ViewBag.state,"state1","State1"),"Select")
                                          </td>
                   <td>District:@Html.DropDownListFor(x
=>x.District, new SelectList(ViewBag.district,"district1","district1"),"Select")</td>
                   </tr>
               
               </table>
                &nbsp; <input type="submit" value="Submit" />
               </fieldset>
      
}
   
</div>
</body>
</html>
