Data Binding with Windows Forms 2.0: Programming Smart Client Data Applications with .NET

Building Data-Bound Applications with Windows FormsIT IS ALMOST impossible to design a significant application without dealing with data in some form. If the application is a simple arcade game, the data may be a log of past scores or configuration data that lets a user customize the way the application behaves. If the application is a graphical design tool, the data may be a complex graph of objects that need to be manipulated by the application and by the user and saved when the application or document is closed. If the application is a high-end enterprise business application, the data might be an aggregation of complex relational data residing in multiple distributed databases, objects, and files used in the processing that the application performs.

To build any of these kinds of applications, you need a good way to store the data, load it, and manipulate it. If the data will be exposed directly to the user through a presentation tier application, you need intuitive ways to present the data and let the user interact with it. Most of this book is focused on just thatproviding rich data presentation and interaction for users of your Windows Forms applications. However, there is a lot more to building a good data-bound application than just the presentation aspects. This chapter not only introduces the key concepts of data binding, it also tries to paint the picture of the bigger context in which your Windows Forms application lives.
