In a multiple-column combo box on a form or report, the text box portion of the combo box displays data from the first visible column in the list. You use the ColumnWidths property to determine which columns are visible. For example, if you have a combo box that is based on a query that includes the SupplierID field and the SupplierName field, in that order, then Microsoft Access displays the SupplierID field in the text box portion of the combo box unless you hide it using the ColumnWidths property.
