Chapter 27. ASP.NET Development

It has often been the case with Web development that the tools available, however powerful, don't quite match up with your requirements for a specific project. Perhaps a given control doesn't quite work as you'd like it to, or perhaps one section of code, intended for reuse on several pages, is too complex in the hands of multiple developers. In cases such as these, there is a strong argument for building your own controls. Such controls can, at their simplest, wrap multiple existing controls together, perhaps with additional properties specifying layout. They can also be completely unlike any existing control. Using a control you have built yourself can be as simple as using any other control in ASP.NET (if you have written them well), which can certainly ease Web site coding.

In the first part of this chapter, you examine the options available to control developers, and assemble some simple user controls of your own. You also look at the basics of more advanced control construction, although you won't see these in any great depth; whole books are devoted to the subject.

Next, you look at master pages, a technique new to ASP.NET 2.0 that enables you to provide templates for your Web sites. Using master pages you can implement complex layouts on Web pages throughout a Web site with a great deal of code reuse.
