Will,
Let your baseclass code run with a dummy controlsource first (ie: prod_type), then change its properties.

*grid.init
dodefault()
for each oColumn in this.Columns
if upper(oColumn.ControlSource) = this.Recordsource+'.PROD_TYPE'
 oColumn.Header1.Caption = 'Product Type'
 oColumn.Text1.Controlsource = '(iif(...))'
 exit
endwith
endfor

*Or instead of iif
oColumn.Addobject('myCombo','Combobox')
with oColumn.myCombo
.Additem('Intl')
.Additem('Def')
endwith
oColumn.Currentcontrol = 'myCombo'
oColumn.sparse = .f.

Fox2x style format still exists with 'M' format property but I don't think it would be suitable.
