In this chapter, we took a brief look at Web Parts from an ASP.NET point of view. Web Parts are like server-side controls on steroids. They provide layout and control management above and beyond normal server-side controls. The Web Part architecture is built around three fundamental concepts: WebPart zones, Web Parts themselves, and the server-side controls that may populate them. Web Parts are especially useful for portal-type applications because of their ability to leverage the personalization and customization facilities of ASP.NET 2.0.
