In this article you will learn about ASP.NET Core and Angular 2 Master Detail HTML grid using Web API and EF 1.0.1.


In this article, let’s see how to create our own ASP.NET Core, Angular 2 Master Detail HTML Grid using Template pack, Entity Framework 1.0.1, and Web API to display Master and Detail data from database to our Angular2 and ASP.NET Core web application.

Kindly read my previous articles which explains in depth about getting started with ASP.NET Core Angular 2 EF 1.0.1 Web API Using Template Pack.

In this article, let’s see:

  • Creating sample database and Student Master and Detail Table in SQL Server to display in our web application.
  • How to create ASP.NET Core Angular 2 Starter Application (.NET Core) using Template pack.
  • Creating EF, DBContext Class and Model Class.
  • Creating Web API.
  • Creating our first component TypeScript file to get Web API JSON result using HTTP Module.
  • Creating our first component HTML file to bind the data to Master and Detail HTML Grid.

This article will explain how to create a Master /Detail Table and bind the Master related details in inner HTML table to show the output as Master/Detail Grid. Here, in this article, we have used the Student Master and Student Detail relation to show the Master/Detail Grid. In Student Master, we store student ID, Name, Email, Phone and Address. In Student Details, we store the students' final exam results for displaying Student Major, Studying Year with Term, and Grade details.

Here, in the below image, we can see that when the user clicks on the Student ID “2”,  then the next details Grid was being displayed to show student results in detail by Major,Year, Term, and Grade.

Here, we are displaying student details by each student Id.


Make sure you have installed all the following prerequisites in your computer. If not, then download and install them all, one by one.

  1. First, download and install Visual Studio 2015 with Update 3 from this link.
  2. If you have Visual Studio 2015 and have not yet updated with update 3, download and install the Visual Studio 2015 Update 3 from this link.
  3. Download and install .NET Core 1.0.1
  4. Download and install TypeScript 2.0
  5. Download and install Node.js v4.0 or above. I have installed V6.9.1
  6. Download and install Download ASP.NET Core Template Pack visz file

Using the code

Step 1 Create a Database and Table

We will create a Student Master and Student Detail table to be used for the Master and Detail Grid data binding. 

The following is the script to create a database, table and sample insert query. Run this script in your SQL Server. I have used SQL Server 2014.

--1) Check  
-- for the Database Exists.If the database is exist then drop and create new DB  
IF EXISTS(SELECT[name] FROM sys.databases WHERE [name] = 'StudentsDB')  
USE StudentsDB  
--1) //////////// StudentMasters  
IF EXISTS(SELECT[name] FROM sys.tables WHERE[name] = 'StudentMasters')  
DROP TABLE StudentMasters  
CREATE TABLE[dbo].[StudentMasters](  
        [StdName][varchar](100) NOT NULL, 
        [Email][varchar](100) NOT NULL, 
        [Phone][varchar](20) NOT NULL, 
        [Address][varchar](200) NOT NULL  
    --insert sample data to Student Master table  
INSERT INTO[StudentMasters]([StdName], [Email], [Phone], [Address])  
VALUES('Shanu', '', '01030550007', 'Madurai,India')  
INSERT INTO[StudentMasters]([StdName], [Email], [Phone], [Address])  
VALUES('Afraz', '', '01030550006', 'Madurai,India')  
INSERT INTO[StudentMasters]([StdName], [Email], [Phone], [Address])  
VALUES('Afreen', '', '01030550005', 'Madurai,India')  
select * from[StudentMasters]  
IF EXISTS(SELECT[name] FROM sys.tables WHERE[name] = 'StudentDetails')  
DROP TABLE StudentDetails  
CREATE TABLE[dbo].[StudentDetails](  
        [StdID] INT ,
        [Major][varchar](100) NOT NULL, 
        [Year][varchar](30) NOT NULL, 
        [Term][varchar](30) NOT NULL, 
        [Grade][varchar](10) NOT NULL 
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(1,'Computer Science','First Year','First Term','A')  
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(1,'Computer Science','First Year','Second Term','B')  
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(1,'Computer Science','Second Year','First Term','C')  
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(2,'Computer Engineer','Third Year','First Term','A')  
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(2,'Computer Engineer','Third Year','Second Term','A')  
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(3,'English','First Year','First Term','C')  
INSERT INTO[StudentDetails]([StdID], [Major], [Year], [Term],[Grade])  
VALUES(13,'Economics','First Year','First Term','A')   
select * from StudentDetails

Step 2 Create ASP.NET Core Angular 2 application

After installing all the prerequisites listed above and ASP.NET Core Template, click Start >> Programs >> Visual Studio 2015 >> Visual Studio 2015, on your desktop. Click New >> Project. Select Web >> ASP.NET Core Angular 2 Starter. Enter your project name and click OK.

Angular2, ASP .NET Core 1.0.1, Entity Framework, en-US, has code, has image, has See Also, Has TOC, MVC, mvp author, SYED SHANU, Web API 2

We will be using all this in our project to create, build, and run our Angular 2 with ASP.NET Core Template Pack, Web API, and EF 1.0.1.

Step 3 Creating Entity Freamework

Add Entity Framework Packages.

To add our Entity Framework Packages in our ASP.NET Core application, open the Project.JSON file and in dependencies, add the below line too.

"Microsoft.EntityFrameworkCore.SqlServer": "1.0.1",
 "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final"

When we save the project,.json file we can see the Reference was been Restoring.

After few second we can see Entity framework package has been restored and all reference has been added. 

Adding Connection String

To add the connection string with our SQL connection, open the “appsettings.json” file. Yes, this is a JSON file and this file looks like below image by default.

In this appsettings.json file add our connection string  

"ConnectionStrings": {
    "DefaultConnection": "Server=YOURDBSERVER;Database=StudentsDB;user id=SQLID;password=SQLPWD;Trusted_Connection=True;MultipleActiveResultSets=true;"

Note change the SQL connection string as per your local connection.

Next step is we create a folder named “Data” to create our model and DBContext class.

Creating Model Class for Student Master

We can create a model by adding a new class file in our Data Folder. Right click the Data folder and click Add > Class. Enter the class name as StudentMasters and click "Add".

Now in this class we first create property variable, add studentMaster. We will be using this in our WEB API controller. 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.ComponentModel.DataAnnotations;
namespace Angular2ASPCORE.Data
    public class StudentMasters
        public int StdID { get; set; } 
        [Display(Name = "Name")]
        public string StdName { get; set; } 
        [Display(Name = "Email")]
        public string Email { get; set; } 
        [Display(Name = "Phone")]
        public string Phone { get; set; } 
        public string Address { get; set; }

Creating Model Class for Student Detail

We can create a model by adding a new class file in our Data folder. Right click Data folder and click Add >Class. Enter the class name as StudentDetails and click Add.

Now in this class we first create property variable, add StudentDetails . We will be using this in our WEB API controller. 

public class StudentDetails
        public int StdDtlID { get; set; }
        [Display(Name = "StudentID")]
        public int StdID { get; set; }
        [Display(Name = "Major")]
        public string Major { get; set; }
        [Display(Name = "Year")]
        public string Year { get; set; }
        [Display(Name = "Term")]
        public string Term { get; set; }
        public string Grade { get; set; }

Creating Database Context

DBContext is Entity Framework Class for establishing a connection to database. We can create a DBContext class by adding a new class file in our Data folder. Right click Data folder and click Add > Class. Enter the class name as StudentContext and click Add.

In this class, we inherit DbContext and created Dbset for our studentMasters and StudentDetails table.

using System;  
namespace Angular2ASPCORE.Data {  
    publicclassstudentContext: DbContext {  
        publicstudentContext(DbContextOptions < studentContext > options): base(options) {}  
        publicstudentContext() {}  
        publicDbSet < StudentMasters > StudentMasters {  
        publicDbSet < StudentDetails > StudentDetails {  


Now, we need to add our database connection string and provider as SQL Server. To add this, we add the below code in Startup.cs file under ConfigureServices method.

// Add Entity framework .
            services.AddDbContext<studentContext>(options =>

Step 4 Creating Web API

To create our WEB API Controller, right click Controllers folder. Click "Add" and click "New Item".

Click ASP.NET in right side > Click Web API Controller Class. Enter the name as “StudentMastersAPI.cs” and click Add.

In this we are using only Get method to get all the students result from database and bind the final result using Angular2 to html file.

Here in this web API we get both Student Master , Student Details and Student Details load by condition student ID.

    public class StudentMastersAPI : Controller
        private readonly studentContext _context;  
        public StudentMastersAPI(studentContext context)
            _context = context;
        // GET: api/values
// For Student Master
        public IEnumerable<StudentMasters> GetStudentMasters()
            return _context.StudentMasters;  
        // GET: api/values
// For Student Detail
        public IEnumerable<StudentDetails> GetStudentDetails()
            return _context.StudentDetails;  
// For Student Detail with studentid to load by student ID
        // GET api/values/5
        public IEnumerable<StudentDetails> GetStudentDetails(int id)
            return _context.StudentDetails.Where(i => i.StdID == id).ToList();

 To test it we can run our project and copy the get method api path here we can see our API path for get is api/StudentMastersAPI/Student.Run the program and paste the above API path to test our output.

To get the Student Details by Student ID. Here we can see all the Student Details for Student ID=1 has been loaded. api/StudentMastersAPI/Details/1

Working with Angular2

We create all Angular 2 related Apps Modules, Services, Components and HTML templates under ClientApp/App folder.

We create “students” folder under app folder to create our TypeScript and HTML file for displaying Student details.

Step 5 Creating our First Component TypeScript

Right click on Students folder and click on "Add new Item". Select Client-side from left side . Select TypeScript file and name the file as “students.component.ts” and click Add.

In students.component.ts file we have three parts first is the,

  1. import part
  2. Next is component part
  3. Next we have the class for writing our business logics.First we import angular files to be used in our component here we import http for using http client in our Angular2 component. 

In component we have selector and template. Selector is to give a name for this app and in our html file we use this selector name to display in our html page.
In template we give our output html file name. here we will create on html file as “students.component.html”.

Export Class is the main class where we do all our business logic and variable declaration to be used in our component template. In this class we get the API method result and bind the result to the student array.  

Here we get first all the Student Master data from web API to bind in our html page. We have created one more function named “getStudentsDetails” to this function we pass the Student ID to load only the selected Student ID related data from Student Detail tables. We call this function from button click of each Student Master.

import { Component } from '@angular/core';
import { Http } from "@angular/http";
    selector: 'students',
    template: require('./students.component.html')
export class studentsComponent {
    public student: StudentMasters[] = [];
    public studentdetails: StudentDetails[] = [];
    myName: string;
    activeRow: string = "0";
    constructor(public http: Http) {
        this.myName = "Shanu";
    getStudentMasterData() {
        this.http.get('/api/StudentMastersAPI/Student').subscribe(result => {
            this.student = result.json();
    getStudentsDetails(StudID) {
        this.http.get('/api/StudentMastersAPI/Details/' + StudID).subscribe(result => {
            this.studentdetails = result.json();
        this.activeRow = StudID; 
//// For Student Master
export interface StudentMasters {
    stdID: number;
    stdName: string;
    email: string;
    phone: string;
    address: string;
// For Student Details
export interface StudentDetails {
    StdDtlID: number;
    stdID: number;
    Major: string;
    Year: string;
    Term: string;
    Grade: string;

Step 6 Creating our First Component HTML File

Right click on Students folder and click on "Add New Item". Select Client-side from left side and select html file. Name the file “students.component.html” and click "Add".

Write the below html code to bind the result in our html page.

Here we have first created HTML Table for loading the Student Master data with Detail Button.

In the Detail Button click we load the Student Details for selected Student and bind the result according to the table row.

<h1>Angular 2 with ASP.NET Core Template Pack, WEB API and EF 1.0.1 </h1>
<hr />
<h2>My Name is : {{myName}}</h2>
<hr />
<h1>Students Details :</h1>
<p *ngIf="!student"><em>Loading Student Details please Wait ! ...</em></p>
<!--<pre>{{ studentdetails | json }}</pre>-->
<table class='table' style="background-color:#FFFFFF; border:2px #6D7B8D; padding:5px;width:99%;table-layout:fixed;" cellpadding="2" cellspacing="2" *ngIf="student">
    <tr style="height: 30px; background-color:#336699 ; color:#FFFFFF ;border: solid 1px #659EC7;">
        <td  width="80" align="center"></td>
        <td width="80" align="center">Student ID</td>
        <td width="240" align="center">Student Name</td>
        <td width="240" align="center">Email</td>
        <td width="120" align="center">Phone</td>
        <td width="340" align="center">Address</td>
    <tbody *ngFor="let StudentMasters  of student">
        <tr><td align="center" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">
                <button (click)=getStudentsDetails(StudentMasters.stdID) style="background-color:#334668;color:#FFFFFF;font-size:large;width:80px;
            <td align="center" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">
                <span style="color:#9F000F">{{StudentMasters.stdID}}</span>
            <td align="left" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">
                <span style="color:#9F000F">{{StudentMasters.stdName}}</span>
            <td align="left" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">
                <span style="color:#9F000F">{{}}</span>
            <td align="center" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">
                <span style="color:#9F000F">{{}}</span>
            <td align="left" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">
                <span style="color:#9F000F">{{StudentMasters.address}}</span>
        <tr *ngIf="activeRow==StudentMasters.stdID">
            <td colspan="6" style="border: solid 1px #659EC7; padding: 5px;table-layout:fixed;">  
                <table class='table' style="background-color:#ECF3F4; border:2px #6D7B8D; padding:5px;width:99%;table-layout:fixed;" cellpadding="2" cellspacing="2" *ngIf="studentdetails">
                      <tr style="height: 30px; background-color:#659EC7 ; color:#FFFFFF ;border: solid 1px #659EC7;">
                         <td width="100" align="center"><Strong>Student Detail --></Strong>   </td>
                        <td width="240" align="center">Major</td>
                        <td width="240" align="center">Year</td>
                        <td width="120" align="center">Term</td>
                        <td width="340" align="center">Grade</td>  
                    <tbody *ngFor="let stddetails  of studentdetails">
                            <td width="100" align="center"></td>
                            <td width="240" align="center">{{stddetails.major}}</td>
                            <td width="240" align="center">{{stddetails.year}}</td>
                            <td width="120" align="center">{{stddetails.term}}</td>
                            <td width="340" align="center">{{stddetails.grade}}  </td>

Step 7 Adding Students Navigation menu

We can add our newly created Student Details menu in existing menu.

To add our new navigation menu, open the “navmenu.component.html” under navmenumenu. Write the below code to add our navigation menu link for students. Here, we have removed the existing "Count and Fetch" menu.

            </span> Students </a>  

Step 8 App Module

App Module is the root for all files and we can find the app.module.ts under ClientApp\app to import our students component.

import {  
} from './components/students/students.component';  
Next in @NGModule add studentsComponent  
In routing add our students path.  
The code will be looks like this  
import {  
} from '@angular/core';  
import {  
} from '@angular/router';  
import {  
} from 'angular2-universal';  
import {  
} from './components/app/app.component'  
import {  
} from './components/navmenu/navmenu.component';  
import {  
} from './components/home/home.component';  
import {  
} from './components/fetchdata/fetchdata.component';  
import {  
} from './components/counter/counter.component';  
import {  
} from './components/students/students.component';  
    bootstrap: [AppComponent],  
    declarations: [  
    imports: [  
        UniversalModule, // Must be first import. This automatically imports BrowserModule, HttpModule, and JsonpModule too.  
            path: '',  
            redirectTo: 'home',  
            pathMatch: 'full'  
        }, {  
            path: 'home',  
            component: HomeComponent  
        }, {  
            path: 'counter',  
            component: CounterComponent  
        }, {  
            path: 'fetch-data',  
            component: FetchDataComponent  
        }, {  
            path: 'students',  
            component: studentsComponent  
        }, {  
            path: '**',  
            redirectTo: 'home'  
exportclassAppModule {} 

Step 9 Build and run the application

Build and run the application. You can see that our Students Master/Detail page will be loaded with all Student, Master, and Details information.

Points of Interest

First, create the database and table in your SQL Server. You can run the SQL Script from this article to create StudentsDB database and StudentMasters and StudentDetails Tables. Also, don’t forget to change the connection string in “appsettings.json”.
