Thanks Princy ... none of the examples were a direct solution.
I was finally able to get a simple master page converted to a master/detail. I moved the MasterTableView stuff to DetailTables/GridTableView section and had to work through a few strange problems. I do have some code behind, where in the grid UpdateCommand I find a control and place in a temp var and in the ODS updating, place the temp var value in my class. I have a working edit in the Detail rows (nothing in the master).
