AngularJs: CRUD operations in Asp.net MVC 5

In this article I am going to explain how to perform Create, read, Update and Delete (CRUD) operations in Asp.net MVC 5 using AngularJs.

AngularJs CRUD operations in Asp.net MVC 5



Description:
In this angularjs tutorial I am going to perform create, read, update and delete (CRUD) operations.

Implementation:

I have created a table Employee. I want to insert, edit and delete employee information like name, phone number, email id etc. and also going to display all employees in grid.

Model (Employee.cs):
  public partial class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public Nullable<int> Phone { get; set; }
        public Nullable<int> Salary { get; set; }
        public string Department { get; set; }
        public string EmailId { get; set; }
    }


Add Controller
I have added empty controller to project. Now create a Json action for CRUD opration.

Compete code of Controller (Democontroller.cs):-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MVC_Project.Models;
namespace MVC_Project.Controllers
{
    public class DemoController : Controller
    {
        //
        // GET: /Demo/
        DemoEntities1 db = new DemoEntities1();

        public ActionResult Index()
        {
            return View();
        }
        public JsonResult GetEmployee()
        {
            var emp = db.Employees.ToList();
            return Json(emp, JsonRequestBehavior.AllowGet);
        }
        [HttpPost]
        public JsonResult InsertEmployee(Employee emp)
        {
            db.Employees.Add(emp);
            db.SaveChanges();
            string message = "Success";
            return new JsonResult { Data = message, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
        }

        [HttpPost]
        public JsonResult UpdateEmployee(int id, string name, string department, int phone, int salary, string emailId)
        {
            var emp = db.Employees.Where(x => x.Id == id).FirstOrDefault();
            emp.Name = name;
            emp.Phone = phone;
            emp.Department = department;
            emp.Salary = salary;
            emp.EmailId = emailId;          
            db.SaveChanges();
            return Json(emp, JsonRequestBehavior.AllowGet);
        }
        [HttpDelete]
        public JsonResult DeleteEmployee(int id)
        {
            Employee emp = db.Employees.Find(id);
            db.Employees.Remove(emp);
            db.SaveChanges();
            return Json(emp, JsonRequestBehavior.AllowGet);
        }
        [HttpGet]
        public JsonResult getByid(int id)
        {
            Employee emp = db.Employees.Find(id);
            return Json(emp, JsonRequestBehavior.AllowGet);
        }
      

    }
}



Add View
Add view for Index action.

Complete code of view (index.cshtml):

@{
    ViewBag.Title = "AngularJs Tutorial";
}
<style>

</style>
