CRUD Operations using jQuery dialog, Entity Framework and ASP.NET MVC: An Overview

Insert, Update, Delete, View in MVC using Entity Framework jQuery dialog can be easily achieved if we clearly know how to do that. This tutorial will demonstrate, how to create an Asp.Net MVC application with CRUD (Create, Read, Update, Delete) Operations using jQuery and Entity Framework code. For deeper knowledge on it, enroll yourself in our ASP.NET MVC Training.

Suppose you have following data model and DataContext classes in EF.

public class User
 {
 public int UserID { get; set; }
 [Required(ErrorMessage = "Please Enter Your Name")]
 public string Name { get; set; }
 [Required(ErrorMessage = "Please Enter Your Address")]
 public string Address { get; set; }
 [Required(ErrorMessage = "Please Enter Your Contact No")]
 public string ContactNo { get; set; }
 }

public class DataContext : DbContext
 {
 public DataContext()
 : base("DefaultConnection")
 {

 }

 public DbSet<User> Users { get; set; }
 }

Now migrate your data model class into SQL Server database by using EF code first database migration. For more help refer this link Understanding Entity Framework Code First Migrations

Controller for handling CRUD Operations

public class UserController : Controller
 {
 private DataContext db = new DataContext();

 // GET: /User/
 public ActionResult Index()
 {
 return View(db.Users.ToList());
 }

 // GET: /User/Details/5
 public ActionResult Details(int id = 0)
 {
 User user = db.Users.Find(id);
 if (user == null)
 {
 return HttpNotFound();
 }
 return View(user);
 }

 // GET: /User/Create
 public ActionResult Create()
 {
 return PartialView();
 }

 // POST: /User/Create
 [HttpPost]
 [ValidateAntiForgeryToken]
 public ActionResult Create(User user, string Command)
 {
 if (ModelState.IsValid)
 {
 db.Users.Add(user);
 db.SaveChanges();
 TempData["Msg"] = "Data has been saved succeessfully";
 return RedirectToAction("Index");
 }

 return View(user);
 }

 // GET: /User/Edit/5
 public ActionResult Edit(int id = 0)
 {
 User user = db.Users.Find(id);
 if (user == null)
 {
 return HttpNotFound();
 }
 return View(user);
 }

 // POST: /User/Edit/5
 [HttpPost]
 [ValidateAntiForgeryToken]
 public ActionResult Edit(User user)
 {
 if (ModelState.IsValid)
 {
 db.Entry(user).State = EntityState.Modified;
 db.SaveChanges();
 TempData["Msg"] = "Data has been updated succeessfully";
 return RedirectToAction("Index");
 }
 return View(user);
 }

 // GET: /User/Delete/5
 public ActionResult Delete(int id)
 {
 User user = db.Users.Find(id);
 db.Users.Remove(user);
 db.SaveChanges();
 TempData["Msg"] = "Data has been deleted succeessfully";
 return RedirectToAction("Index");
 }

 protected override void Dispose(bool disposing)
 {
 db.Dispose();
 base.Dispose(disposing);
 }
 }
