When version 1.0 of the .NET platform was released, programmers who needed to build graphical desktop applications made use of two APIs named Windows Forms and GDI+, packaged up primarily in the System.Windows.Forms.dll and System.Drawing.dll assemblies. While Windows Forms/GDI+ are excellent APIs for building traditional desktop GUIs, Microsoft shipped an alternative GUI desktop API named Windows Presentation Foundation (WPF) beginning with the release of .NET 3.0. This initial WPF chapter begins by examining the motivation behind this new GUI framework, which will help you see the differences between the Windows Forms/GDI+ and WPF programming models. Next, we will examine the different types of WPF applications supported by the API, and come to know the role of the several important classes including Application, Window, ContentControl, Control, UIElement, and FrameworkElement. During this time, you will learn to intercept keyboard and mouse activities, define application wide data, and other common WPF tasks using nothing but C# code. This chapter will then introduce you to an XML-based grammar named Extensible Application Markup Language (XAML). Here, you will learn the syntax and semantics of XAML, including attached property syntax, the role of type converters, markup extensions, and understanding how to generate, load and parse XAML at runtime. As well, you will learn how to integrate XAML data into a C# WFP-code base (and the benefits of doing so). This chapter wraps up by the integrated WPF designers of Visual Studio 2010. Here, you will build your own custom XAML editor/parser, which illustrates how XAML can be manipulated at runtime to build dynamic user interfaces.

block. Blocks that are dynamic in nature, related to a module you ve written, or that consist of mostly PHP code are excellent candidates for using the block API and for being implemented within a module. Try to avoid storing PHP code in custom blocks, as code in the database is harder to maintain than code written in a module. A site editor can come along and accidentally delete all that hard work too easily. Rather, if it doesn t make sense to create a block at the module level, just call a custom function from within the block and store all that PHP code elsewhere.

Note The remaining WPF chapters of this book will introduce you to Microsoft Expression Blend, which is a WPF-centric tool dedicated to the generation of XAML on your behalf.

Over the years, Microsoft has created numerous graphical user interface toolkits (raw C/C++/Windows API development, VB6, MFC, etc.) to build desktop executables. Each of these APIs provided a code base to represent the basic aspects of a GUI application, including main windows, dialog boxes, controls, menu systems, and other basic necessities. With the initial release of the .NET platform, the Windows Forms

Tip A common practice for blocks and other components that are site-specific is to create a site-specific module and place the custom functionality for the site inside that module. For example, the developer of a web site for the Jones Pies and Soda Company may create a jonespiesandsoda module.

API quickly became the preferred model for UI development, given its simple yet very powerful object model. While many full-featured desktop applications have been successfully created using Windows Forms, the fact of the matter is that this programming model is rather asymmetrical. Simply put, System.Windows.Forms.dll and System.Drawing.dll do not provide direct support for many additional technologies required to build a feature-rich desktop application. To illustrate this point, consider the ad hoc nature of GUI development before the release of WPF (e.g., .NET 2.0; see Table 27-1). Table 27-1. .NET 2.0 Solutions to Desired Functionalities

Although the block API is relatively simple, don t disregard the complexity of what you can do within that framework. Blocks can display just about anything you want (that is, they are written in PHP and thus are not limited in what they can do), but they usually play a supporting role to the main content of the site. For example, you could create a custom navigation block for each user role, or you could expose a block that lists comments pending approval.

As you can see, a Windows Forms developer must pull in types from a number of unrelated APIs and object models. While it is true that making use of these diverse APIs may look similar syntactically (it is just C# code, after all), you may also agree that each technology requires a radically different mind-set. For example, the skills required to create a 3D rendered animation using DirectX are completely different from those used to bind data to a grid. To be sure, it is very difficult for a Windows Forms programmer to master the diverse nature of each API.
