Web Development with Blazor

By: Jimmy Engström

Overview of this book

Blazor is an essential tool if you want to build interactive web apps without JS, but it comes with its own learning curve. Web Development with Blazor will help you overcome most common challenges developers face when getting started with Blazor and teach you the best coding practices. You’ll start by learning how to leverage the power of Blazor and explore the full capabilities of both Blazor Server and Blazor WebAssembly. Then you’ll move on to the practical part, which is centred around a sample project – a blog engine. This is where you’ll apply all your newfound knowledge about creating Blazor Server and Blazor WebAssembly projects, the inner working of Razor syntax, and validating forms, as well as creating your own components. You’ll learn all the key concepts involved in web development with Blazor, which you’ll also be able to put into practice straight away. By showing you how all the components work together practically, this book will help you avoid some of the common roadblocks that novice Blazor developers face and inspire you to start experimenting with Blazor on your other projects. When you reach the end of this Blazor book, you'll have gained the confidence you need to create and deploy production-ready Blazor applications.

Exploring form elements

There are many form elements in HTML, and we can use them all in Blazor. In the end, what Blazor will output is HTML.

Blazor does have components that will add to the functionality, so we can and should try to use those components instead of HTML elements. This will give us great functionality for free; we will come back to this later in this chapter.

Blazor offers the following components:

  • EditForm
  • InputBase<>
  • InputCheckbox
  • InputDate<TValue>
  • InputNumber<TValue>
  • InputSelect<TValue>
  • InputText
  • InputTextArea
  • InputRadio
  • InputRadioGroup
  • ValidationMessage
  • ValidationSummary

Let's go through them all.

EditForm

EditForm renders as a form tag but it has a lot more functionalities.

First, we are not going to have an action or method like with traditional form tags; Blazor will handle all of that.

EditForm will create an EditContext instance as a cascading value so...
