Now I am even more confused.

Above you said it is not to be used alone. I guess I don't know what "act on its own" means. If it means outside a DataSource, 
then how would the control know what connection to use?

It sounds here as though you are talking about the DataCombo:
"This control lets you edit the value of a field through another table whose primary key is that field."

not the DataComboView:
"This control implements a combo-box that allows user to choose a record inside a table."

The phrase, "use it alone", according to what I have read above would mean NOT inside a DataSource. I don't know how a 'Click' 
event would help the DataComboView know what connection to use outside of a DataSource.


What would be useful to me is to have the DataComboView do exactly what it claims it does but with some mechanism to determine 
what record was chosen by the user.

But, this thread can be put to rest. There ways to accomplish what I need other than using DataComboView. Thank you for trying.
