Telerik Toolsets for ASP.NET Web Forms and Blazor: Part 1

ASP.NET Web Forms: The Strong Presence and Mature Experience

In existence since 2002 and still actively used, the Web Forms technology has successfully passed the harsh test of time and the rigorous demands of web developers.

Some of the key features and recognizable traits of Web Forms are the ViewState and Event-driven development. In MVC and Core, these were replaced with the concept of Model-View-Controller pattern. Now, Blazor is the newest member of the ASP.NET family and brings yet another system of implementation, actually two different ways, which will be explained in the dedicated Blazor-Hosting section. One major difference is that it can also run in ASP.NET Core, whereas Web Forms cannot.

Blazor: A Bold Experiment by Microsoft Turned Out to Be a Big Success in Web Development

Microsoft’s newest web development framework Blazor is now officially released both for its server-side and client-side flavors and ready for production use. With constantly growing community, it surely has the buzz around it. But before answering what is Blazor actually, we need to clarify couple of stepping stones which lay the foundation of this new framework.

Naming

The name Blazor comes from the following equation: Browser + Razor = Blazor.

There is another strong possibility, according to the Blazor team that, “When pronounced, it is also the name of a swanky jacket worn by hipsters that have excellent taste in fashion, style, and programming languages.”

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.

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

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

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.
