Overview of this book

Windows Presentation Foundation (WPF) provides developers with a unified programming model for building rich Windows smart client user experiences that incorporate UI, media, and documents.WPF has become the leading technology for developing rich client applications on the Windows platform, packed with features and capabilities. However, WPF is big; in fact, it's huge, causing a steep learning curve for the beginner and even for those already using some WPF features.Windows Presentation Foundation 4.5 Cookbook provides clear recipes for common WPF tasks. It includes detailed explanations and code examples for customizing and enhancing the basic scenarios, while gaining a deep understanding of WPF mechanics and capabilities.WPF is different and requires a different mind-set and approach. This book provides recipes and insights not only in its design but also its practical implementation details.Starting from the foundations of WPF, such as dependency properties and XAML, the book touches on all major WPF aspects, such as controls and layout, resources, and digs deep into its unprecedented data binding capabilities.The book shows data and control templates in action, which allow full customizations of displayed data and controls in a declarative way. Supported by styles and resources makes data binding all the more powerful. The Model View View-Model pattern is presented as an effective way of maximizing decoupling of components, while providing an elegant way of expanding applications while maintaining a tight grip on complexity.The later parts discuss custom elements and controls ñ the ultimate customization mechanism, and looks at multithreading issues, and how .NET 4.5 task parallelism features can enhance application performance.

Applying transforms on elements


Transforms allow manipulating an entity's coordinates in various ways, the most common being translating (moving), scaling, and rotating. This ability provides a lot of flexibility in the way elements (and other objects) present themselves. Combined with animations and some creativity, transforms are even more powerful. In this recipe, we'll examine the ways to use transforms and discuss the available transform types.

Getting ready

Make sure Visual Studio is up and running.

How to do it...

We'll create some images and apply a rotation transform to some, showing the common properties that accept transforms:

  1. Create a new WPF application named CH09.Transforms.

  2. Add an existing image to the project, such as "penguins.jpg" from the Sample Pictures folder.

  3. Open MainWindow.xaml. Add the following properties to the Window:

    SizeToContent="WidthAndHeight" FontSize="16" 
        ResizeMode="CanMinimize"
  4. Remove the Width and Height property settings of the Window.

  5. Add three columns...
