Is there a way to implement the Master-Detail view of the DevExpress grid via the Enhanced List?  If so, what is the easiest way to go about this and is there documentation somewhere I can look at?

The enhanced list was designed as an extended control using a GridView.  All of the internal code actually looks at the MainView property, but I am pretty sure there are some strong-typings within the code that expect the behavior of a GridView.  So the answer is "No."  You can however do this with a standard DevExpress grid and use the CurrentView or CurrentDataTable property of a BO as the data source.  If you do this then you will be able to use any of the views supported by a DevExpress grid.
