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.

MVC

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

Step 1

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

  1. CREATE TABLE [dbo].[Employee] (
  2. [Id] INT IDENTITY (1, 1) NOT NULL,
  3. [Name] NVARCHAR (50) NOT NULL,
  4. [Address] NVARCHAR (50) NOT NULL,
  5. [Country] NVARCHAR (50) NOT NULL,
  6. [City] NVARCHAR (50) NOT NULL,
  7. [Mobile] NVARCHAR (10) NOT NULL,
  8. PRIMARY KEY CLUSTERED ([Id] ASC)
  9. );

Step 2

Create a stored procedure.

  1. CREATE PROCEDURE sp_InsUpdDelEmployee
  2. @id INT ,
  3. @name NVARCHAR(50) ,
  4. @address NVARCHAR(50) ,
  5. @country NVARCHAR(50) ,
  6. @city NVARCHAR(50) ,
  7. @mobile NVARCHAR(50) ,
  8. @type VARCHAR(10)
  9. AS
  10. BEGIN
  11. IF ( @type = 'Ins' )
  12. BEGIN
  13. INSERT INTO Employee
  14. VALUES ( @name, @address, @country, @city, @mobile )
  15. END
  16. IF ( @type = 'Upd' )
  17. BEGIN
  18. UPDATE Employee
  19. SET Name = @name ,
  20. [Address] = @address ,
  21. Country = @country ,
  22. City = @city ,
  23. Mobile = @mobile
  24. WHERE Id = @id
  25. END
  26. IF ( @type = 'Del' )
  27. BEGIN
  28. DELETE FROM Employee
  29. WHERE Id = @id
  30. END
  31. IF ( @type = 'GetById' )
  32. BEGIN
  33. SELECT *
  34. FROM Employee
  35. WHERE Id = @id
  36. END
  37. SELECT *
  38. FROM Employee
  39. END

Step 3

Open Visual Studio and click File > New > Project.

Step 4

Click on Web from the left-side panel and select ASP.NET MVC4 Web Application, give name, and click OK.

Step 15

Write Following code in Model

  1. namespace AngularJs_With_Web_API.Models
  2. {
  3. using System;
  4. using System.Collections.Generic;
  6. public partial class Employee
  7. {
  8. public int Id { get; set; }
  9. public string Name { get; set; }
  10. public string Address { get; set; }
  11. public string Country { get; set; }
  12. public string City { get; set; }
  13. public string Mobile { get; set; }
  14. }
  15. }

Step 16

Now, Write Following code in BundleConfig.cs File

  1. using System.Web;
  2. using System.Web.Optimization;
  4. namespace AngularJs_With_Web_API
  5. {
  6. public class BundleConfig
  7. {
  8. // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkId=254725
  9. public static void RegisterBundles(BundleCollection bundles)
  10. {
  11. bundles.Add(new ScriptBundle("~/js").Include(
  12. "~/js/angular.js",
  13. "~/js/app.js"));
  15. bundles.Add(new StyleBundle("~/css").Include(
  16. "~/css/bootstrap.css"));
  17. }
  18. }
  19. }

Step 17

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

  1. @Scripts.Render("~/js")
  2. @Styles.Render("~/css")
  4. <html ng-app="myApp">
  5. <head><title>AngularJs With WebApi and Stored Procedure</title></head>

  8. $scope.updateShow = false;
  9. $scope.addShow = true;
  11. // Get All Employee

  40. });
  41. }
  43. $scope.update = function () {
  44. $scope.loading = true;
  45. console.log(this.newemployee);
  46. $http.put('/api/EmployeeAPI/', this.newemployee).success(function (data) {
  47. $scope.employees = data;
  48. $scope.updateShow = false;
  49. $scope.addShow = true;

  64. });
  65. }
  67. //Cancel Employee
  68. $scope.cancel = function () {
  69. $scope.updateShow = false;
  70. $scope.addShow = true;
  71. $scope.newemployee = '';
  72. }
  73. }

Step 19

Now, Write Following code in ControllerFile.

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Web;
  5. using System.Web.Mvc;
  7. namespace AngularJs_With_Web_API.Controllers

  9. public class TestController : Controller
  10. {
  11. public ActionResult Index()
  12. {
  13. return View();
  14. }
  15. }
  16. }

Step 20

Now, Write Following code in WebApiConfig.cs File

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;

  11. {
  12. config.Routes.MapHttpRoute(
  13. name: "DefaultApi",
  14. routeTemplate: "api/{controller}/{id}",
  15. defaults: new { id = RouteParameter.Optional }
  16. );
  18. // Uncomment the following line of code to enable query support for actions with an IQueryable or IQueryable return type.
  19. // To avoid processing unexpected or malicious queries, use the validation settings on QueryableAttribute to validate incoming queries.
  20. // For more information, visit http://go.microsoft.com/fwlink/?LinkId=279712.
  21. //config.EnableQuerySupport();

  112. }
  113. return Request.CreateResponse(HttpStatusCode.OK, emplist);
  114. }
  115. }
  117. // Prevent Memory Leak
  118. protected override void Dispose(bool disposing)
  119. {
  120. using (dbEntities db = new dbEntities())
  121. db.Dispose();
  122. base.Dispose(disposing);
  123. }
  124. }
  125. }

Summary

In this article, I clearly explained how to perform CURD operations in ASP.NET MVC with AngulerJS using Web API and also explain how to use Stored Procedure. I hope this article will help the beginners.
