ListBox component
Use the ListBox component to display choices for the user in a fixed-size box. The values in a list can be file names, records, array elements, table names, or field names.
If you’re trying to decide whether to use a ListBox component (fixed-size, multiple selection) or a ComboBox component (drop-down list), use the following guidelines:
If you have room to show the open list, or want to let users select more than one item from a list, use a ListBox. A ListBox displays only existing field values; users cannot change those values.
If you do not have room, or you want the user to be able to type a value, use a ComboBox control. A ComboBox drop-down list allows the selection of only one item.
By default, the designers allow one selection per ListBox control. To permit multiple selections in a list, set the multiple property to true.
To specify list items to appear in a ListBox control,
Click the wrench tool beside the ListBox's options property.
In the DataSource Property Builder, select a dataSource option in the drop-down Type box.
Complete the information in the dialog box, and click OK.
