combobox in a datagrid

[vidachristy]

I am sure someone out there has placed a combobox in a datagrid, only i cant
seem to find an example or documentation on how it is to be accomplished.

I need to put a dropdown box in a datagrid. The combobox should have the
initial selected item as the value of the dataprovider for the datagrid in that
field. And i should be able to take the selected item in the combobox and pass
it to the dataprovider/datagrid as a value to be posted in the database.

Anyone out there accomplish this? The closest I've come is to begin work with
an itemeditor....

Thanks in advance...
