问题 I ran into a problem where I had an Html.DropDownList in my view that would postback the selected value the first time I submitted the form, but each subsequent postback would only post data from the initial postback.

But my {controller} portion of the url is not decided pre-hand, but it is dynamically determined at run time, how do I create a "dynamic controller" that maps anything to the same controller which then based on the value and determines what to do? Same thing with {action}, if the {action} portion of my url is also dynamic, is
