Introduction

In this article, I am going to explain how to do CRUD operations in ASP.NET MVC AngularJS using WEB API 2 with Stored Procedure.

So, you should follow these steps to create a web application.

Step 1

Create a new database table. You can follow this query.

CREATE TABLE [dbo].[Employee] (  
    [Id]      INT           IDENTITY (1, 1) NOT NULL,  
    [Name]    NVARCHAR (50) NOT NULL,  
    [Address] NVARCHAR (50) NOT NULL,  
    [Country] NVARCHAR (50) NOT NULL,  
    [City]    NVARCHAR (50) NOT NULL,  
    [Mobile]  NVARCHAR (10) NOT NULL,  
    PRIMARY KEY CLUSTERED ([Id] ASC)  
);  

Step 2

Create a stored procedure.

CREATE PROCEDURE sp_InsUpdDelEmployee  
    @id INT ,  
    @name NVARCHAR(50) ,  
    @address NVARCHAR(50) ,  
    @country NVARCHAR(50) ,  
    @city NVARCHAR(50) ,  
    @mobile NVARCHAR(50) ,  
    @type VARCHAR(10)  
AS   
    BEGIN  
        IF ( @type = 'Ins' )   
            BEGIN  
                INSERT  INTO Employee  
                VALUES  ( @name, @address, @country, @city, @mobile )  
            END  
        IF ( @type = 'Upd' )   
            BEGIN  
                UPDATE  Employee  
                SET     Name = @name ,  
                        [Address] = @address ,  
                        Country = @country ,  
                        City = @city ,  
                        Mobile = @mobile  
                WHERE   Id = @id  
            END  
        IF ( @type = 'Del' )   
            BEGIN  
                DELETE  FROM Employee  
                WHERE   Id = @id  
            END   
        IF ( @type = 'GetById' )   
            BEGIN  
                SELECT  *  
                FROM    Employee  
                WHERE   Id = @id  
            END  
        SELECT  *  
        FROM    Employee  
    END  

Step 3

Step 15

Write Following code in Model

namespace AngularJs_With_Web_API.Models
{
    using System;
    using System.Collections.Generic;
 
    public partial class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Address { get; set; }
        public string Country { get; set; }
        public string City { get; set; }
        public string Mobile { get; set; }
    }
}  

Step 16

Now, Write the following code in BundleConfig.cs File

using System.Web;  
using System.Web.Optimization;  
  
namespace AngularJs_With_Web_API  
{  
    public class BundleConfig  
    {  
        // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkId=254725  
        public static void RegisterBundles(BundleCollection bundles)  
        {  
            bundles.Add(new ScriptBundle("~/js").Include(  
                "~/js/angular.js",  
                "~/js/app.js"));  
  
            bundles.Add(new StyleBundle("~/css").Include(  
                "~/css/bootstrap.css"));  
        }  
    }  
}  

Step 17

Now, If talking about VIEW then Write the Following code in the Index.cshtml File

@Scripts.Render("~/js")
@Styles.Render("~/css")
 
<html ng-app="myApp">
<head><title>AngularJs With WebApi and Stored Procedure</title></head>
<body>
    <div ng-controller="employeeController" class="container">

            <div class="col-md-12">
                <h3 class="header">AngularJs With WebApi and Stored Procedure</h3>
            </div>
        </div>
        <div class="row">            
            <div class="col-md-12">
                <strong class="error">{{error}}</strong>

                    </div>
                    <br />
                    <div class="form-group space">
                        <div class="col-sm-offset-2 col-sm-10">

                        </div>
                    </div>
                    <br />
                </form>
            </div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <div class="table-responsive">
                    <table class="table table-bordered table-hover" style="width: 800px; margin-left: 170px;">
                        <tr>

                            <th>Actions</th>
                        </tr>
                        <tr ng-repeat="employee in employees">
                            <td>

                        </tr>
                    </table>
                </div>
            </div>
        </div>        
    </div>
</body>
</html>

Step 18

Now, Write the following code in App.js File.

var app = angular.module('myApp', []);
app.controller('employeeController', ['$scope', '$http', employeeController]);
 
// Angularjs Controller
function employeeController($scope, $http) {
    // Declare variable
    $scope.loading = true;
    $scope.updateShow = false;
    $scope.addShow = true;
 
    // Get All Employee
    $http.get('/api/EmployeeAPI/').success(function (data) {
        $scope.employees = data;        
    }).error(function () {
        $scope.error = "An Error has occured while loading posts!";
    });
 
    //Insert Employee
    $scope.add = function () {
        $scope.loading = true;
        $http.post('/api/EmployeeAPI/', this.newemployee).success(function (data) {
            $scope.employees = data;            
            $scope.updateShow = false;
            $scope.addShow = true;
            $scope.newemployee = '';
        }).error(function (data) {
            $scope.error = "An Error has occured while Adding employee! " + data;            
        });
    }
 
    //Edit Employee
    $scope.edit = function () {
        var Id = this.employee.Id;
        $http.get('/api/EmployeeAPI/' + Id).success(function (data) {
            $scope.newemployee = data;
            $scope.updateShow = true;
            $scope.addShow = false;
        }).error(function () {
            $scope.error = "An Error has occured while loading posts!";
        });
    }
 
    $scope.update = function () {
        $scope.loading = true;
        console.log(this.newemployee);
        $http.put('/api/EmployeeAPI/', this.newemployee).success(function (data) {
            $scope.employees = data;
            $scope.updateShow = false;
            $scope.addShow = true;
            $scope.newemployee = '';
        }).error(function (data) {
            $scope.error = "An Error has occured while Saving employee! " + data;
        });
    }
 
    //Delete Employee
    $scope.delete = function () {
        var Id = this.employee.Id;
        $scope.loading = true;
        $http.delete('/api/EmployeeAPI/' + Id).success(function (data) {
            $scope.employees = data;            
        }).error(function (data) {
            $scope.error = "An Error has occured while Saving employee! " + data;
        });
    }
 
    //Cancel Employee
    $scope.cancel = function () {
        $scope.updateShow = false;
        $scope.addShow = true;
        $scope.newemployee = '';
    }
}

Step 20

Now, Write the following code in WebApiConfig.cs File

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
 
namespace AngularJs_With_Web_API
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
 
            // Uncomment the following line of code to enable query support for actions with an IQueryable or IQueryable<T> return type.
            // To avoid processing unexpected or malicious queries, use the validation settings on QueryableAttribute to validate incoming queries.
            // For more information, visit http://go.microsoft.com/fwlink/?LinkId=279712.
            //config.EnableQuerySupport();
        }
    }
}

Step 21

Now, Write the following code in API Controller

using AngularJs_With_Web_API.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Data;
using System.Data.Entity.Infrastructure;
 
namespace AngularJs_With_Web_API.Controllers
{
    public class EmployeeAPIController : ApiController
    {
        // Get All The Employee
        [HttpGet]
        public List<Employee> Get()
        {
            List<Employee> emplist = new List<Employee>();
            using (dbEntities db = new dbEntities())
            {
                var results = db.sp_InsUpdDelEmployee(0, "", "", "", "", "", "Get").ToList();
                foreach (var result in results)
                {

                    {
                        Id = result.Id,
                        Name = result.Name,
                        Address = result.Address,
                        Country = result.Country,
                        City = result.City,
                        Mobile = result.Mobile
                    };
                    emplist.Add(employee);
                }
                return emplist;
            }
        }
 
        // Get Employee By Id
        public Employee Get(int id)
        {
            using (dbEntities db = new dbEntities())
            {
                Employee employee = db.Employees.Find(id);
                if (employee == null)
                {
                    throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotFound));
                }
                return employee;
            }
        }
 
        // Insert Employee
        public HttpResponseMessage Post(Employee employee)
        {
            if (ModelState.IsValid)
            {
                using (dbEntities db = new dbEntities())
                {
                    var emplist = db.sp_InsUpdDelEmployee(0, employee.Name, employee.Address, employee.Country, employee.City, employee.Mobile, "Ins").ToList();
                    HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Created, emplist);
                    return response;
                }
            }
            else
            {
                return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
            }
        }
 
        // Update Employee
        public HttpResponseMessage Put(Employee employee)
        {
            List<sp_InsUpdDelEmployee_Result> emplist = new List<sp_InsUpdDelEmployee_Result>();
            if (!ModelState.IsValid)
            {
                return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
            }
            using (dbEntities db = new dbEntities())
            {
                try
                {
                    emplist = db.sp_InsUpdDelEmployee(employee.Id, employee.Name, employee.Address, employee.Country, employee.City, employee.Mobile, "Upd").ToList();
                }
                catch (DbUpdateConcurrencyException ex)
                {
                    return Request.CreateErrorResponse(HttpStatusCode.NotFound, ex);
                }
            }
            return Request.CreateResponse(HttpStatusCode.OK, emplist);
        }
 
        // Delete employee By Id
        public HttpResponseMessage Delete(int id)
        {
            using (dbEntities db = new dbEntities())
            {
                List<sp_InsUpdDelEmployee_Result> emplist = new List<sp_InsUpdDelEmployee_Result>();
                var results = db.sp_InsUpdDelEmployee(id, "", "", "", "", "", "GetById").ToList();
                if (results.Count == 0)
                {
                    return Request.CreateResponse(HttpStatusCode.NotFound);
                }
                try
                {
                    emplist = db.sp_InsUpdDelEmployee(id, "", "", "", "", "", "Del").ToList();
                }
                catch (DbUpdateConcurrencyException ex)
