I want to know about the availability of Forms APIs for ASP.NET, either for MVC or WebForms. I am learning about Django right now, and I really love their forms APIs. Having a similar thing in .net will be very interesting as most of my time is wasted on UI issues.
Microsoft Dynamic Data gives me similar features, but it's not mature enough (from my POV). Integrating with your own business later is important. Inserting inline items (.e.g Order and OrderDetail at once) is very important also.
Do you know about libraries/frameworks which provide the same thing?
