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.

How it works...

As you see from the preceding example, each FrameworkElement exposes a property named ContextMenu, which can hold a ContextMenu item. Just like the menu, as we learnt in the previous recipe, the context menu can also hold multiple items as MenuItem, and each menu item can again hold one or more menu items to make the context menu hierarchical.

Labels of menu items are assigned by setting its Header property. You can also set icons for each menu item, by assigning an image or a Unicode character to its Icon property. If you have binded a command to the menu, you can assign the shortcut key text as InputGestureText property.

Additionally, you can create checkable context menu items. As shown in the Menu item 3, you can set the IsCheckable property to True, to make the menu checkable. Then you can use the IsCheck property to show/hide the check mark on it.

To add a separator between a group of context menu items, you can use the <Separator /> tag, as shown in the preceding...
