Simple ASP.NET ?

I've been told on more than one occasion by several people to always use coding to do your application. Limit your design building to a minimum, so when I'm in trying to create a dataset, or connection, or a command for that matter, do I always have to drag & drop one of the forementioned items onto my webform? I've never really found any information stating one way or the other is the best way to go or do both. Just curious.It seems to me a lot of trouble has gone in to designing the .NET Frameworks and Visual Studio .NET to allow the opposite of what you've been told. Yes, of course everything CAN be done in code, you never have to drag-and-drop (anything that can be done in VS can also be done in Notepad, with more sweat applied). But why re-invent the wheel on routine tasks that are handled for you?
