If you set the Bound Column property to 0, Access saves the list index instead of a value from one of the columns.
This is useful if you want to store a sequence of numbers instead of the list value. In the Column Widths property box, type 0 for the column or columns that you want to hide. For example, suppose you have a bound two-column combo box that has a 0. The SupplierID Column can still be the bound column, even though it is hidden. Note: In a combo box, the first visible column is displayed in the text box portion of the combo box when the list isn't displayed.
For example, the SupplierName column in the previous example would be displayed because the SupplierID column is hidden. In the Column Heads property box, click Yes to display column headings.
Headings in combo boxes appear only when the list is open. If the combo box or list box is based on a record source, Access uses the field names from the record source as the column headings.

Combo boxes in Access also support the display of multiple columns so you can show more data to make it easier to select the right item.
Each has articles describing them in more detail. In forms, the BeforeUpdate event is used to validate the entries in the current record. For Combo Boxes, people often check if the value exists by looking for Null.
This works in most cases, but not all. If the combo box is on a bound field, there may be an existing value that is not valid. For example, the value may have been in the list when it was originally selected, but the current list of allowed values has changed. If you simply check for IsNull, Access says it is not null.
This is accurate, but what you really want to know is if a valid value was selected. Use the following syntax to automatically select the first item in a Combo Box when the form loads, or when the value of another control on the form changes:.
This lets you default to the first value and rely on the value in the current list rather than hardcoding a specific value.
On a form with multiple Combo Boxes, you may want to make the selection in one Combo Box limit the choices in another Combo Box. To do this, add code to the AfterUpdate event of the first control that updates the RowSource property of the second control:.
If the list is based on a table that is updated with new values after the combo box is loaded, the new values do not automatically appear in the list. F9 refreshes the combo box list with the current data. For data entry of addresses, we like to speed data entry and improve accuracy by forcing users to select countries from a combo box list, along with state if it's a country with a state list.
Additionally, we use a zip code lookup table to fill in city and state values. This improve accuracy by eliminating typos on city names and flagging wrong zip codes if the city doesn't match. Some zip codes have multiple acceptable cities. With a zip code lookup table from the US Postal Service provided by our Total Zip Code Database subscription , we can easily provide a lookup for city and state, plus add a Combo Box for selecting valid city names:.
