Perform Master Detail CRUD operations in ASP.NET Core (Part 4)

In Part 2 and Part 3 of this article series we completed TeamsComtroller and TeamMembersController respectively. All of the controller actions that we wrote so far return Main view. They also supply a MasterDetailViewModel object to the Main view. In this part we will begin developing a set of views and partials that renders the UI of the application.

jQuery Ajax CRUD in ASP.NET Core MVC with Modal Popup

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.

To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.

Sub-topics discussed :

• Form design for insert and update operation.
• Display forms in modal popup dialog.
• Form post using jQuery Ajax.
• Implement MVC CRUD operations with jQuery Ajax.
• Loading spinner in .NET Core MVC.
• Prevent direct access to MVC action method.

Create ASP.NET Core MVC Project

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).

From new project window, Select Asp.Net Core Web Application_._

Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.

Setup a Database

Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.

Now let’s define DB model class file – /Models/TransactionModel.cs.

public class TransactionModel
{
    [Key]
    public int TransactionId { get; set; }

    [Column(TypeName ="nvarchar(12)")]
    [DisplayName("Account Number")]
    [Required(ErrorMessage ="This Field is required.")]
    [MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
    public string AccountNumber { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Beneficiary Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BeneficiaryName { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Bank Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BankName { get; set; }

    [Column(TypeName ="nvarchar(11)")]
    [DisplayName("SWIFT Code")]
    [Required(ErrorMessage = "This Field is required.")]
    [MaxLength(11)]
    public string SWIFTCode { get; set; }

    [DisplayName("Amount")]
    [Required(ErrorMessage = "This Field is required.")]
    public int Amount { get; set; }

    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }
}

C#Copy

Here we’ve defined model properties for the transaction with proper validation. Now let’s define  DbContextclass for EF Core.

MVC User Registration & Login with ASP.NET Core Identity

User registration and authentication are mandatory in any application when you have little concern about privacy. Hence all most all application development starts with an authentication module. In this article, we will discuss the quickest way to use **ASP.NET Core Identity for User Login and Registration **in a new or existing MVC application.

Sub-topics discussed :

• How to add ASP.NET Core Identity to MVC application.
• Customize ASP.NET Core Identity.
• Identity.UI Design Customization.
• Next step.

Background

ASP.NET Core Identity is an API, which provides both user interface(UI) and functions for user authentication, registration, authorization, etc. Modules/ APIs like this will really be helpful and fasten the development process. It comes with ASP.NET Core Framework and used in many applications before. Which makes the API more dependable and trustworthy.

ASP.NET Core MVC with user authentication can easily be accomplished using Identity.UI. While creating the MVC project, you just need to select Authentication as Individual User Accounts.

The rest will be handled by ASP.NET Core Identity UI. It already contains razor view pages and backend codes for an authentication system. But that’s not what we want in most of the cases. we want to customize ASP.NET Core Identity as per our requirement. That’s what we do here.

Create an ASP.NET Core MVC Project

First of all, I will create a brand new ASP.NET Core MVC application without any authentication selected. We could add ASP.NET Core Identity later into the project.

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N). From new project window, select ASP.NET Core Web Application.

Once you provide the project name and location. A new window will be opened as follows, Select _Web Application(Model-View-Controller), _uncheck _HTTPS Configuration _and DO NOT select any authentication method. Above steps will create a brand new ASP.NET Core MVC project.

Perform Master Detail CRUD operations in ASP.NET Core (Part 4)

In Part 2 and Part 3 of this article series we completed TeamsComtroller and TeamMembersController respectively. All of the controller actions that we wrote so far return Main view.

Perform Master Detail CRUD operations in ASP.NET Core (Part 1)

Master-detail pages are quite common in many web applications. There are various approaches to building master-detail pages including server side, client side, and hybrid. There are also many third-party controls and plugins that can be used to accomplish this task. It would be interesting for beginners to learn and understand how master-detail pages work and how they can be developed in ASP.NET Core. To that end this multipart article explains how master-detail pages can be developed using purely server side code without relying on any third-party component or library.

Asp.Net Core MVC CRUD with EF Core

Create Asp.Net Core MVC Project

In Visual Studio, Goto File > New > Project ( Ctrl + Shift + N). Then select Asp.Net Core Web Application.

In template wizard, Select Web Application( MVC ) template. Make sure to select latest Asp.Net Core Version from top dropdown. We don’t need to configure this application with HTTPS (Unchecked corresponding option from bottom).

Setup Database for EF Core

For this application development, we will use EF Core – Code First Approach. First of all, we have to install NuGet Package for EFCore. for that you can right click on project in solution explorer, click on Manage NuGet Packages. In Browse tab, search for Microsoft.EntityFrameworkCore. Install the package with same version as that of Asp.Net Core.

We will create the DBContext class inside Models folder. To demonstrate Asp.Net Core CRUD Operation, we will deal with employee details like Full Name, Employee Code,Position and Office Location. So I have named the DbContext as EmployeeContext.

Copy to Clipboard

public class Employee
{
    [Key]
    public int EmployeeId { get; set; }

    [Column(TypeName ="nvarchar(250)")]
    [Required(ErrorMessage ="This field is required.")]
    [DisplayName("Full Name")]
    public string FullName { get; set; }

    [Column(TypeName = "varchar(10)")]
    [DisplayName("Emp. Code")]
    public string EmpCode { get; set; }

    [Column(TypeName = "varchar(100)")]
    public string Position { get; set; }

    [Column(TypeName = "varchar(100)")]
    [DisplayName("Office Location")]
    public string OfficeLocation { get; set; }
}

Inside the class, we have a DbSet property for Employees Collection of the type Employee class. So we have to define the class with required properties as follows.
