What you could do is use a LookupComboBox and populated this with the values of the field you want displayed. At the same time maintain a list of the indexfield of the lookuptable. When the users picks a value from your combobox, find the corresponding indexfield in the other list.
It works both ways. When a record is displayed, search in your list for the value to show in the combobox and set its itemindex accordingly.
This will give you an idea of the direction you could take, I may be able to give you an example tonight (dutch time
) or else tomorrow. (Ik heb helaas geen Lazarus op mijn werk.
