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.

Multi-bindings

Multi-binding is a powerful feature in XAML data binding that allows you to bind a single target property to multiple source properties and then apply logic to produce one single value. This technique is particularly useful when a target property’s value depends on more than one source property. The simplest example of this is using StringFormat.

Multi-binding StringFormat

A typical multi-binding scenario is where you would like to display multiple values in one label. We could, of course, create a property on the ViewModel that concatenates those values, or we could define this as a Multi-binding with StringFormat.

As an example, we want to show the author of the recipe next to the Last updated timestamp that we already have on our page (Figure 4.9):

Figure 4.9: Showing the author next to the Last updated timestamp

Here’s how it’s done:
