Key Skills & Concepts
●Perform Screen Layout
●Use Controls
●Work with Data in the UI
Windows Presentation Foundation (WPF) is a .NET technology for building desktop applications. The result of building a WPF application is an *.exe file that you can
run directly on your computer or deploy and run on any other computer that has .NET installed. With WPF, you can add a graphical user interface (GUI), pronounced “Gooey,” that makes it easier for users to work with your program. This chapter will show you how to lay out a screen in WPF and explain the controls, such as Button and TextBox, that you can place on the screen. You’ll also learn how to capture events off controls, allowing you to add code that runs based on user input. Since most applications work with data, this chapter builds on what you learned in Chapter 7 and shows how to bind data to controls in the GUI.
This chapter will show you how to build a WPF GUI with the VS Designer, but sometimes you must work at a lower level and manipulate the XAML, pronounced “Zammel,” that defines the GUI. XAML is an XML format that WPF and Silverlight use to define a GUI. There are two appendixes in this book that will help you get up to speed in XAML: Appendix A, “Introduction to XML,” and Appendix B, “Introduction to XAML.” If you aren’t familiar with XML, start with Appendix A. However, if you have a good grasp of basic XML syntax, go straight to Appendix B. I’ll try to explain WPF in a way that any XAML you see can be understood in its context, but you might want to review the appendixes to avoid any confusion. Once you’re familiar with XAML, you can return here and start with the next section, which explains how to start a WPF project.
Starting a WPF Project
In Chapter 5, you learned how to create and build projects. The example explained how to create a Console application. However, what you learned there is generally applicable to most other application types. This section builds upon what you already know about projects and explains what is unique to a WPF application. To get started, open the New Project window; select WPF Application; and fill in the project name, location, and
