Overview of this book

Blazor WebAssembly is a revolutionary technology in software development that enables you to develop web applications with a rich user interface using C# without JavaScript. It can be run natively in the browser and soon on mobile apps with .NET MAUI, making it a superweapon in the .NET developer’s toolbox. This capability has opened the doors for the JavaScript community to have a stable framework to build single page applications (SPAs) maintained by Microsoft and driven by the community. Mastering Blazor WebAssembly is a complete resource that teaches you everything you need to build client-side web applications using C# & .NET 7.0. Throughout this book, you’ll discover the anatomy of a Blazor WebAssembly project, along with the build, style, and structure of the components. You’ll implement forms to catch user input and collect data, as well as explore the topics of navigating between the pages in depth. The chapters will guide you through handling complex scenarios like RenderTrees, writing efficient unit tests, using variant security methods, and publishing the app to different providers, all in a practical manner. By the end of this book, you’ll have the skills necessary to build web apps with Blazor WebAssembly, along with the basics for a future in mobile development with .NET MAUI and Blazor.

Developing a custom input component

Blazor contains a class called InputBase<T>, which is the base class for all the input components that we have seen so far. The great thing about this class is that we can use it to develop our own input component with the same specifications as the built-in ones.

InputBase<T> has a method called TryParseValueFromString, which is the main method that we need to override, and this is where we can locate the logic that processes the string of the input and translates it into something more meaningful. There is also a property called CurrentValue, which we can use to bind our insider input to.

Blazor already has an InputDate component that gets rendered to an input tag of the date type in HTML, so in the next example, we are going to create a custom component called InputTime, which will be translated to the input tag of the time type. We can bind a TimeOnly value to it. Let’s get started:
