Mastering Windows Presentation Foundation - Second Edition

By: Sheridan Yuen

Overview of this book

Microsoft Windows Presentation Foundation (WPF) provides a rich set of libraries and APIs for developers to create engaging user experiences. This book features a wide range of examples, from simple to complex, to demonstrate how to develop enterprise-grade applications with WPF. This updated second edition of Mastering Windows Presentation Foundation starts by introducing the benefits of using the Model-View-View Model (MVVM) software architectural pattern with WPF, then moves on, to explain how best to debug our WPF applications. It explores application architecture, and we learn how to build the foundation layer of our applications. It then demonstrates data binding in detail, and examines the various built-in WPF controls and a variety of ways in which we can customize them to suit our requirements. We then investigate how to create custom controls, for when the built-in functionality in WPF cannot be adapted for our needs. The latter half of the book deals with polishing our applications, using practical animations, stunning visuals and responsive data validation. It then moves on, to look at improving application performance, and ends with tutorials on several methods of deploying our applications.

Animating along a path

There is one further method of animating property values in WPF. Using PathFigure and PathSegment objects, we can construct a PathGeometry object and then animate a property value according to the X, Y and/or rotation angle values of the path.

As this method is primarily used for animating objects along a complex path and therefore not aimed at typical business applications, we will cover only the basics of this functionality here. As with the other kinds of animation classes, there are different path animation types that manipulate different CLR types. Path animation classes follow the naming convention <Type>AnimationUsingPath.

Each <Type>AnimationUsingPath class has a PathGeometry property that we can use to specify a path to animate along, using an object of type PathGeometry. In order to take advantage of the ability to animate the path X and Y values in addition to the rotation angle, we need to use a MatrixTransform element. Let's see an...
