Group: Forum Members Posts: 87, Visits: 779	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? Attachments combobox_properties.gif (245 views, 77.00 KB) dbnull_error.gif (239 views, 62.00 KB) sql_data.gif (212 views, 63.00 KB) textbox_properties.gif (232 views, 76.00 KB)
