The MVVM Pattern in .NET MAUI

By: Pieter Nijs

Overview of this book

In today's fast-paced world of modern software development, teams need to be efficient, productive, and capable of rapidly adapting to changes to deliver high-quality products, making it crucial for developers to write maintainable and easy-to-test code. The MVVM Pattern in .NET MAUI helps you to thoroughly explore the Model-View-View Model (MVVM) design pattern. The chapters show you how this pattern helps in structuring code to embrace the separation of concerns, allowing for loosely coupled user interface and application logic, which ultimately empowers you to write more robust, maintainable, and testable code. The book also highlights .NET MAUI's capabilities and features, and enables you to delve into the essential components within the framework that facilitate the application of the MVVM pattern. With the help of a sample application, this definitive guide takes a hands-on approach to walk you through both the essential and advanced usages of the MVVM pattern to ensure that you successfully apply the practical aspects of the pattern to your .NET MAUI projects. By the end of this book, you’ll have gained a comprehensive understanding of the MVVM design pattern and its relevance in the context of .NET MAUI, as well as developed the skills needed to successfully apply it in practice.

Implementing input validation on ViewModels

Input validation can be implemented in various ways and at different points within the life cycle of user interaction. It could happen as soon as a user changes a property, providing immediate feedback on the validity of the data entered. On the other hand, it might be performed only when the user initiates a certain action, such as clicking a button, thereby offering a more cumulative validation experience. Deciding on when and how to implement validation often depends on the specific requirements of your project. It’s a balance between the need for immediate feedback and maintaining a smooth, uninterrupted user flow. There’s no one-size-fits-all solution, and the strategy can vary based on the complexity of the data, the form of user interaction, and the overall design of your application.

Implementing validation on the frontend offers several advantages: it provides users with immediate feedback, ensuring a more responsive...
