Many people will probably reference this section as something that I shouldn t have written about because it s controversial. Copying code into another application creates duplication. Duplication isn t something people do inadvertently. Your editor doesn t force you to copy and paste some code. You do it knowingly. Duplication means that you take something from somewhere else and paste it into your code to solve your problem. Let s get back to the duplication behavior and focus on why duplication happens. I stated that duplication happens knowingly. However, in some situations, duplication occurs unknowingly, and not because of a copy-and-paste operation. In those situations, duplication happens because two developers happen to be developing the same type of code without knowing it. A classic example involves the universal string class used when developing C++ code. Everybody and their grandmother had a pet project on developing the best string implementation. With the introduction of STL, this behavior is stopping, but it does happen with other pieces of functionality. Another reason for duplication is that it s imposed. This happens when source code is too complicated for somebody to understand. So instead of refactoring the code to make it understandable, that programmer rewrites the same piece of code, but using his or her improved coding style. So if you do duplicate code knowing the problems that it will generate, there must be a perceived benefit. The perceived benefit can easily be illustrated. Consider the following declaration:

When an ASP .NET page is created using the code-behind model, two derived classes are actually created. The first is the code-behind, which uses the Page class as its base class. The second is the ASPX file itself, which is actually a type that inherits from the class that s defined in the code-behind (as shown in Figure 3-1).

With the common functionality in the master page, Login.aspx, and Global.asax covered, it is possible to move on to the business functionality itself. As I mentioned earlier, I ll walk through the RolesEdit, ProjectList, and ProjectEdit web forms in some detail. ResourceList and ResourceEdit are available in the download and follow the same implementation approach. All of these web forms will be created using the new data binding capabilities built into ASP .NET 2.0 and the CslaDataSource control discussed in 5. These capabilities allow the web developer to easily link controls on the form to business objects and their properties. The developer productivity gained through this approach is simply amazing. Other key technologies I ll be using are the MultiView control and the associated View control. These controls make it easy for a single page to present multiple views to the user, and are often very valuable when building pages for editing data. Finally, remember that all these pages are content pages. This means that they fit within the context of a master page in this case, MasterPage.master. As you ll see, the tags in a content page are a bit different from those in a simple web form.

Note Real literals without a suffix are of type double, not float!

This is how you request data from a URL and retrieve the data. All the URL loading code up to this point is generic and will work regardless of what type of data you are retrieving. You could be downloading an image to display, a PDF document, or an MP3 podcast anything, really.
