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

Content syntax

This is another type of XAML syntax that is used to set the content of a UI element. It can be set as the value of child elements. The following example demonstrates how to set the text content property of a Border control to hold a Button control as its child element:

    <Border> 
      <Border.Child> 
        <Button Content="Click Here" /> 
      </Border.Child> 
    </Border> 

While using Content syntax, you should remember the following points:

  • The value of a Content property must be contiguous
  • You cannot define an XAML Content property twice within a single instance

Thus, the following is invalid as it will throw XAML error:

    <Border> 
        <Border.Child> 
            <Button Content="Button One" /> 
        </Border.Child> 
        <Border.Child> 
            <Button Content="Button Two" /> 
        </Border.Child> 
    </Border>
