CRUD with SPA, ASP.NET Web API and Angular.js


In this article, I am going to demonstrate a simple process of CRUD in AngularJS with lot of pictorial representations. A picture is worth more than a thousand words, that for causes I believe in an article with proper screenshots. Here I will describe how you will create CRUD in angularjs. I am going to show some successful step to below:


In visual studio web application, use the Client Server architecture. Here is the two process or two application that will be communicating with each other to exchange some information. From the two processes one is acts as a client process and another process acts as a server.

In traditional web applications, the client (browser) which typically makes a request for page to the server to initiates the communication. Then the server processes the request and sends the HTML of the page to the client (browser).

In Single-Page Applications (SPAs) at first the entire page is loaded in the client by the initial request, after that the subsequent action has to update by Ajax request and no need to reload the entire page. The SPA reduces the time by to respond to user actions and result is more fluid experience.

To develop the architecture of a SPA is very hard that are not similar to traditional web applications. However, the most familiar technologies like JavaScript frameworks like AngularJS, ASP.NET Web API, and new styling features of CSS3 make it really easy to design and build SPAs.

In this article, I will show you how to create SPA and CRUD by using ASP.NET Web API, AngularJS.



In this article, you will learn how to:

  • create angular-js CRUD
  • Create a responsive UI using Twitter-Bootstrap



In order to create this application, please follow the above prerequisties. 


This article includes the following exercises:

  1. Creating a Web API
  2. Creating a SPA Interface

Exercise 1: Creating a Web API

To set up a web api application

  1. Open Visual Studio Express 2013 for Web and select File | New > Project... to start a new solution.

5.  Now create database 'Inventory' and table 'Customer' and set primary key Id, Here is the Script below:

USE [Inventory]

DROP TABLE [dbo].[Customer]



CREATE TABLE [dbo].[Customer](
    [Id] [int] NOT NULL,
    [Name] [nvarchar](50) NULL,
    [Address] [nvarchar](50) NULL,
    [City] [nvarchar](50) NULL,
    [Country] [nvarchar](50) NULL,
    [DateOfBirth] [datetime] NULL,
    [Age] [int] NULL,
    [Id] ASC


6.  After createing database and table, now you have to create Entity Frame Work Model Object by this dialog box.

Choose Connection String From this window

10.  In the Entity Data Model Wizerd,  Select yes, Include the sensative data in the connection string, then press next button

Image 9

Choose senstative data in the connection string.

11.  In the Entity Data Model Wizerd, select table and press finish button

12.  Build solution after completing above process

13.  In Solution Explorer, right-click the Controllers folder of the RDLCReport project and select Add | New Controller Item.... and Now create CustomerController by this way

Image 11

choose api controller

Image 12

Choose Api Controller Name

14.  The CustomerController.cs file is then added to the Controllers folder of the RDLCReport project, containing an empty CustomerController class. Add the following assembly before RDLCReport.Controllers namespace

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;

15.  In the CustomerController.cs file, Add the following code into the CustomerController class.

InventoryEntities db = new InventoryEntities();
        //get all customer
        public IEnumerable<Customer> Get()
            return db.Customers.AsEnumerable();

        //get customer by id
        public Customer Get(int id)
            Customer customer = db.Customers.Find(id);
            if (customer == null)
                throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotFound));
            return customer;
        //insert customer
        public HttpResponseMessage Post(Customer customer)
            if (ModelState.IsValid)
                HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Created, customer);
                response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = customer.Id }));
                return response;
                return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
        //update customer
        public HttpResponseMessage Put(int id, Customer customer)
            if (!ModelState.IsValid)
                return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
            if (id != customer.Id)
                return Request.CreateResponse(HttpStatusCode.BadRequest);
            db.Entry(customer).State = EntityState.Modified;
            catch (DbUpdateConcurrencyException ex)
                return Request.CreateErrorResponse(HttpStatusCode.NotFound, ex);
            return Request.CreateResponse(HttpStatusCode.OK);
        //delete customer by id
        public HttpResponseMessage Delete(int id)
            Customer customer = db.Customers.Find(id);
            if (customer == null)
                return Request.CreateResponse(HttpStatusCode.NotFound);
            catch (DbUpdateConcurrencyException ex)
                return Request.CreateErrorResponse(HttpStatusCode.NotFound, ex);
            return Request.CreateResponse(HttpStatusCode.OK, customer);
        //prevent memory leak
        protected override void Dispose(bool disposing)

Exercise 2: Creating the SPA Interface

To do:

1.  Open the Package Manager Console from Tools > Library Package Manager. Type the following command to install the AngularJS.Core NuGet package.

Install-Package AngularJS.Core

2.  In Solution Explorer, right-click the Scripts folder of the RDLCReport project and select Add | New Folder. Name the folder app and press Enter.

3.  Right-click the app folder you just created and select Add | JavaScript File.

Naming the new JavaScript file

5.  In the customerCtrl.js file, add the following code to declare and initialize the AngularJS.

    //create angularjs controller
    var app = angular.module('app', []);//set and get the angular module
    app.controller('customerController', ['$scope', '$http', customerController]);

    //angularjs controller method
    function customerController($scope, $http) {

        //declare variable for mainain ajax load and entry or edit mode
        $scope.loading = true;
        $scope.addMode = false;

        //get all customer information
        $http.get('/api/Customer/').success(function (data) {
            $scope.customers = data;
            $scope.loading = false;
        .error(function () {
            $scope.error = "An Error has occured while loading posts!";
            $scope.loading = false;

        //by pressing toggleEdit button ng-click in html, this method will be hit
        $scope.toggleEdit = function () {
            this.customer.editMode = !this.customer.editMode;

        //by pressing toggleAdd button ng-click in html, this method will be hit
        $scope.toggleAdd = function () {
            $scope.addMode = !$scope.addMode;

        //Inser Customer
        $scope.add = function () {
            $scope.loading = true;
            $'/api/Customer/', this.newcustomer).success(function (data) {
                alert("Added Successfully!!");
                $scope.addMode = false;
                $scope.loading = false;
            }).error(function (data) {
                $scope.error = "An Error has occured while Adding Customer! " + data;
                $scope.loading = false;

        //Edit Customer
        $ = function () {
            $scope.loading = true;
            var frien = this.customer;  
            $http.put('/api/Customer/' + frien.Id, frien).success(function (data) {
                alert("Saved Successfully!!");
                frien.editMode = false;
                $scope.loading = false;
            }).error(function (data) {
                $scope.error = "An Error has occured while Saving customer! " + data;
                $scope.loading = false;

       //Delete Customer
        $scope.deletecustomer = function () {
            $scope.loading = true;
            var Id = this.customer.Id;
            $http.delete('/api/Customer/' + Id).success(function (data) {
                alert("Deleted Successfully!!");
                $.each($scope.customers, function (i) {
                    if ($scope.customers[i].Id === Id) {
                        $scope.customers.splice(i, 1);
                        return false;
                $scope.loading = false;
            }).error(function (data) {
                $scope.error = "An Error has occured while Saving Customer! " + data;
                $scope.loading = false;


6. In the customerCtrl.js, All of the above code, you can put into this javascript function.

(function () {
      'use strict';

   /*Write above code here*/


7.  In _Layout.cshtml page which path is Views> Shared> _Layout.cshtml, add the following line
