AngularJS Chart Bar Series With ASP.NET MVC 5

Introduction

In this article, we will see how to bind data in Chart Bar series, using Web API2, AngularJS, and Entity Framework. In the following example, I want to display the population data, using AngularJS Chart plugin and Web API2.

Let’s go.

Prerequisites

As I said earlier, we are going to use jqxChart plugin in our MVC application. For this, you must have Visual Studio 2015 (.NET Framework 4.5.2) and SQL Server.

SQL Database part

Here, you will find the scripts to create the database and table.

Create Database

USE [master]
GO

/****** Object:  Database [PopulationDB]    Script Date: 9/12/2016 8:54:39 AM ******/
CREATE DATABASE [PopulationDB]
 CONTAINMENT = NONE
 ON  PRIMARY
( NAME = N'PopulationDB', FILENAME = N'c:\Program Files (x86)\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\PopulationDB.mdf' , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON
( NAME = N'PopulationDB_log', FILENAME = N'c:\Program Files (x86)\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\PopulationDB_log.ldf' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO

ALTER DATABASE [PopulationDB] SET COMPATIBILITY_LEVEL = 110
GO

IF (1 = FULLTEXTSERVICEPROPERTY('IsFullTextInstalled'))
begin
EXEC [PopulationDB].[dbo].[sp_fulltext_database] @action = 'enable'
end
GO

ALTER DATABASE [PopulationDB] SET ANSI_NULL_DEFAULT OFF
GO

ALTER DATABASE [PopulationDB] SET ANSI_NULLS OFF
GO

ALTER DATABASE [PopulationDB] SET ANSI_PADDING OFF
GO

ALTER DATABASE [PopulationDB] SET ANSI_WARNINGS OFF
GO

ALTER DATABASE [PopulationDB] SET ARITHABORT OFF
GO

ALTER DATABASE [PopulationDB] SET AUTO_CLOSE OFF
GO

ALTER DATABASE [PopulationDB] SET AUTO_CREATE_STATISTICS ON
GO

ALTER DATABASE [PopulationDB] SET AUTO_SHRINK OFF
GO

ALTER DATABASE [PopulationDB] SET AUTO_UPDATE_STATISTICS ON
GO

ALTER DATABASE [PopulationDB] SET CURSOR_CLOSE_ON_COMMIT OFF
GO

ALTER DATABASE [PopulationDB] SET CURSOR_DEFAULT  GLOBAL
GO

ALTER DATABASE [PopulationDB] SET CONCAT_NULL_YIELDS_NULL OFF
GO

ALTER DATABASE [PopulationDB] SET NUMERIC_ROUNDABORT OFF
GO

ALTER DATABASE [PopulationDB] SET QUOTED_IDENTIFIER OFF
GO

ALTER DATABASE [PopulationDB] SET RECURSIVE_TRIGGERS OFF
GO

ALTER DATABASE [PopulationDB] SET  DISABLE_BROKER
GO

ALTER DATABASE [PopulationDB] SET AUTO_UPDATE_STATISTICS_ASYNC OFF
GO

ALTER DATABASE [PopulationDB] SET DATE_CORRELATION_OPTIMIZATION OFF
GO

ALTER DATABASE [PopulationDB] SET TRUSTWORTHY OFF
GO

ALTER DATABASE [PopulationDB] SET ALLOW_SNAPSHOT_ISOLATION OFF
GO

ALTER DATABASE [PopulationDB] SET PARAMETERIZATION SIMPLE
GO

ALTER DATABASE [PopulationDB] SET READ_COMMITTED_SNAPSHOT OFF
GO

ALTER DATABASE [PopulationDB] SET HONOR_BROKER_PRIORITY OFF
GO

ALTER DATABASE [PopulationDB] SET RECOVERY SIMPLE
GO

ALTER DATABASE [PopulationDB] SET  MULTI_USER
GO

ALTER DATABASE [PopulationDB] SET PAGE_VERIFY CHECKSUM
GO

ALTER DATABASE [PopulationDB] SET DB_CHAINING OFF
GO

ALTER DATABASE [PopulationDB] SET FILESTREAM( NON_TRANSACTED_ACCESS = OFF )
GO

ALTER DATABASE [PopulationDB] SET TARGET_RECOVERY_TIME = 0 SECONDS
GO

ALTER DATABASE [PopulationDB] SET  READ_WRITE
GO

Create Table

USE [PopulationDB]
GO

/****** Object:  Table [dbo].[tbt_Population]    Script Date: 9/12/2016 7:08:26 AM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[tbt_Population](
    [ID] [int] NOT NULL,
    [COUNTRY] [varchar](50) NULL,
    [POPULATION] [bigint] NULL,
    [PERCENT] [decimal](18, 0) NULL,
 CONSTRAINT [PK_tbt_Population] PRIMARY KEY CLUSTERED
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

SET ANSI_PADDING OFF
GO

After creating the table, you can add some records.



Create your MVC application

Now, open "Visual Studio" and select File >> New Project. A new window will pop up with the name New Project. Select ASP.NET Web Application (.NET Framework), name your project, and click OK.



Next, select the Web API template in Template window, and click OK.



After creating the project, add ADO.NET Entity Data Model.

Adding ADO.NET Entity Data Model

First of all, right click on the project name and click Add >> Add New Item. A dialog box will pop up. Inside Visual C#, select Data >> ADO.NET Entity Data Model.

Now, enter name for your Dbcontext model as DbContextPopulation. Finally, click Add.



At this level, we are going to choose "EF Designer from database", as shown below.



In the following snapshot, we need to choose the data connection which should be used to connect to the database. If the connection doesn’t exist, create a new connection by clicking on the "New Connection" button.



After clicking on Next, the Entity Data Model Wizard will pop up for choosing the object which we need to use. In our case, we are choosing tbt_Population table and click Finish. Finally, we see that EDMX model generates tbt_Population class.



Make sure that DbContextPopulation.edmx file figures in Solution Explorer panel.



Create a Controller

Now, create a Controller. Right click on the "Controllers" folder > Add > Controller> selecting Web API 2 Controller – Empty > click Add.



Enter Controller name (‘PopulationController’).



PopulationController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;

namespace AngularJS_Chart_Bar_Series.Controllers
{
    public class PopulationController : ApiController
    {
        //Dbcontext
        private PopulationDBEntities context = new PopulationDBEntities();


        //Get All Population
        [HttpGet]
        public IEnumerable<tbt_Population> GetPopulation()
        {
            var PopulationList = context.tbt_Population.ToList().OrderBy(x => x.COUNTRY);

            return PopulationList;
        }


    }
}

Here, I’m creating GetPopulation() action which will select all data from tbt_Poplulation table.

Adding View

In Home Controller, right click on Index() action and select Add View. In the new pop-up, write a name for your View. Finally, click Add.
