Blazor WebAssembly by Example

By: Toi B. Wright

Overview of this book

Blazor WebAssembly makes it possible to run C# code on the browser instead of having to use JavaScript, and does not rely on plugins or add-ons. The only technical requirement for using Blazor WebAssembly is a browser that supports WebAssembly, which, as of today, all modern browsers do. Blazor WebAssembly by Example is a project-based guide for learning how to build single-page web applications using the Blazor WebAssembly framework. This book emphasizes the practical over the theoretical by providing detailed step-by-step instructions for each project. You'll start by building simple standalone web applications and progress to developing more advanced hosted web applications with SQL Server backends. Each project covers a different aspect of the Blazor WebAssembly ecosystem, such as Razor components, JavaScript interop, event handling, application state, and dependency injection. The book is designed in such a way that you can complete the projects in any order. By the end of this book, you will have experience building a wide variety of single-page web applications with .NET, Blazor WebAssembly, and C#.

Chapter 9: Building an Expense Tracker Using the EditForm Component

Most applications require some data input. The Blazor WebAssembly framework includes many built-in components for inputting and validating data.

In this chapter, we will learn how to use the EditForm component, the various built-in input components, and the built-in input validation components.

The project that we'll create in this chapter will be a travel expense tracker. We will use a multi-project architecture to separate the Blazor WebAssembly app from the ASP.NET Web API endpoints. The page used to add and edit expenses will use the EditForm component as well as many of the built-in input components. It will also use the built-in validation components. We will learn how to use the built-in components to add data input, validation, and submission to any Blazor WebAssembly app.

In this chapter, we will cover the following topics:

  • The EditForm component
  • Using the built-in input components...
