Yes, I never use the IDE to code ASP.NET components, and the differences are not that huge. Of course, just saying "components" is a misnomer. The difference that makes a difference is that these platforms use event-driven composite controls with an explicit and extensible lifecycle. All of these attributes are vital for the platform to work as well as it does. The term "component-orientation" is becoming a code word for a visual object that is an event-driven composite with an extensible lifecycle. Of course, there are other kinds of components too. In my ASP.NET project, we're starting to use custom controls like "tiles". The page is a punch list of the controls it uses, and controls can be shared between pages. Rather than jump between pages, we jump between controls. Like a Tile, each of our controls is a composite of other controls (including other custom controls) and managed by its own code-behind (like a Tile controller). It ends up being a very tidy architecture featuring both DRY and Separation of Concerns. Sure, you can say a component is just a custom tag. You can also say that an object is just a struct with methods. :) -Ted. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
