    Recently we had a project where we needed to render certain questions on the screen dynamically based on answers to previous questions on previous screens.  For questions that need to dynamically be visible/invisible on the same screen, this can simply be controlled with jQuery.  However, in this case, based on the user’s input on previous screens we know there are certain questions that will not be applicable before the current screen even loads.

    In ASP.NET MVC 3 Preview 1, we introduced some syntactic sugar for creating and accessing view data using new dynamic properties. Sugar, it’s not just for breakfast.

From within a view, the View property provides the same thing (see the addendum at the bottom of this post for why these property names do not match). Disc...
