Yes, I realized a while ago that I could get this working using classic binding.  But, I can not get child tables to work under this scenario.  When I define WebGrid.IObjectRelations the same way as DataSource.IObjectRelations in my business class the grid binds and loads the root table without error but does not give me the '+' to expand child rows.  Only if I RetrieveHierchicalStructure at runtime does it provide them.  This is not practical for my solution as I have too many column changes and format conditions to then apply at runtime.  I want to define my columns at design time.  Can you provide me an example of Self-Referencing Load-On-Demand using Custom Business Objects that also has child tables and does not RetrieveHierarchicalStructure at runtime.
