I have been playing with the same problem myself and that seemed to work for me. I still have a problem with when I highlight the combobox it goes blank. This seems to be a problem in VFP with Integers being returned from the combobox.

>>combobox property
>>bountto = .t.
>>
>>>I have one combobox inside a grid.
>>>The combobox has the following properties:
>>>RowSourceType = 3 SQL
>>>RowSource = SELECT description,code from a INTO CURSOR cc
>>>BoundColumn = 2
>>>Sparse = .T.
>>>
>>>When the focus is another grid column diferent than combobox I see
>>>only the code, but if the focus is in grid combobox column I see the
>>>description.
>>>
>>>I would like to use Sparse = .T. and see always the description, independent where the focus is.
>>>
>>>What I am doing wrong?
>
>I tried Bount to = .t. in grid.column1 and combobox. But nothing changed.
>It could be something related with controlSource?
