By: Ricardo Peres

Overview of this book

ASP.NET has been the preferred choice of web developers for a long time. With ASP.NET Core 3, Microsoft has made internal changes to the framework along with introducing new additions that will change the way you approach web development. This second edition has been thoroughly updated to help you make the most of the latest features in the framework, right from gRPC and conventions to Blazor, which has a new chapter dedicated to it. You’ll begin with an overview of the essential topics, exploring the Model-View-Controller (MVC) pattern, various platforms, dependencies, and frameworks. Next, you’ll learn how to set up and configure the MVC environment, before delving into advanced routing options. As you advance, you’ll get to grips with controllers and actions to process requests, and later understand how to create HTML inputs for models. Moving on, you'll discover the essential aspects of syntax and processes when working with Razor. You'll also get up to speed with client-side development and explore the testing, logging, scalability, and security aspects of ASP.NET Core. Finally, you'll learn how to deploy ASP.NET Core to several environments, such as Azure, Amazon Web Services (AWS), and Docker. By the end of the book, you’ll be well versed in development in ASP.NET Core and will have a deep understanding of how to interact with the framework and work cross-platform.

Using Forms and Models

In this chapter, we will learn how to build forms for displaying and capturing data for use in our application, how to bind controls to models, and how to use validation techniques to exclude invalid data. We will cover client-submitted data—namely, HTML forms and their server-side counterpart, models, and files. With these, we will learn how to deal with user-submitted data.

Specifically, we will talk about the following:

  • Using the form context
  • Working with the model
  • Understanding the model metadata and using metadata to influence form generation
  • How can we use HTML helpers to generate HTML
  • Working with templates
  • Binding forms to object models
  • Validating the model
  • Using AJAX
  • Uploading files
