Hello.. this is what I am doing now... Im trying to pupulate the combo box, but i'm gettin this error "Conversion from type 'DBNull' to type 'String' is not valid.". The funny thing is that I have a a text box that loads from the same BO and loads the same field, and it's working..

PS - I dont have any null info on the "nome_clube" field on the table.

Any Clues.. anyone?

Just to verify what you are attempting to do before I send you some code.  You have a combo box that you want to populate with the countries which is bound to a field in the clubs table, correct?  But when you bind and navigate right now it is showing a number (i.e. Primary Key or something) rather than the country description.  Also, I assume that your country database has a primary key and that primary key is tied to the clubs country field, correct?

Country Table                      Club Table
Primary Key - Integer  ----- ClubCountry - Integer
Description - String

The simple table above is just to verify that I understand your data structure and what you are attempting to do.  Please advise and let me know if I understand your situation.  Thanks.
