Windows Presentation Foundation Development Cookbook

Overview of this book

Windows Presentation Foundation (WPF) is Microsoft's development tool for building rich Windows client user experiences that incorporate UIs, media, and documents. With the updates in .NET 4.7, Visual Studio 2017, C# 7, and .NET Standard 2.0, WPF has taken giant strides and is now easier than ever for developers to use. If you want to get an in-depth view of WPF mechanics and capabilities, then this book is for you. The book begins by teaching you about the fundamentals of WPF and then quickly shows you the standard controls and the layout options. It teaches you about data bindings and how to utilize resources and the MVVM pattern to maintain a clean and reusable structure in your code. After this, you will explore the animation capabilities of WPF and see how they integrate with other mechanisms. Towards the end of the book, you will learn about WCF services and explore WPF's support for debugging and asynchronous operations. By the end of the book, you will have a deep understanding of WPF and will know how to build resilient applications.

Using WPF Standard Controls

Event Attribute syntax

When you add a button, you need to associate an event listener to it, to perform some operation. The same is applicable for adding other controls and UI layouts. The XAML allows you to use the Event Attribute syntax to define events for a specific XAML object element.

The syntax looks like a property attribute, but it is used to associate the event listener to the element. The following example demonstrates how to assign the click event to a button control:

    <Button Content="Click Here" Click="OnButtonClicked" /> 

The associated event gets generated from the code behind the XAML page, where you can perform the real action. Here is the code snippet for the event implementation of the preceding button-click event:

    void OnButtonClicked (object sender, RoutedEventArgs e) 
    { 
        // event implementation 
    }
