I have never really found the design view in Visual Studio useful when developing aspx pages, and so I basically never use it.
Am I missing something or is it just o
I generally like to use to as a quick check for does my CSS/HTML look reasonably well prior to checking it in a real browser. It is also handy for simple text manipulation when you want to just enter raw HTML, i.e. editing your HTML resume.
Apparently the new VS 2008 designer has alot of new features for CSS, they may be worth looking at in greater detail. They are mostly directed at dreamweaver esque functionality to allow you to manage/apply styles and CSS.
That said I am using VS 2008 and almost view it under the split view that allows me to see the design and markup at the same time.
Good luck.
