TextColumn Properties of ComboBox
 

When I scroll through the contents of the combo box (ListFillRange set for
two columns) I see the information from both columns. But, when I select the
row I want only one column of information is shown.

I've played around with the Bound Column and TextColumn, but that is only
allows me to switch which column of the two is shown.

Is it possible to have the whole row show in the box after it's clicked?
