Thank you for your input. I think that most of the functionality you depicted can be supported by the standard MS FormView and DetailsView controls. Additionally, note that you can style those controls in harmony with the rest of the AJAX RadControls you have on the page with the help of RadFormDecorator
I hope that such a solution is applicable for your scenario.
