List Box
The List Box displays a scrollable box from which an item can be selected.
When the form control is applied the name entered will display as the caption for the form control. This can be changed by selecting the Caption property.
When an item in the list box is selected the form control reports the exact item as it appears in the control.
Items are added to the control from the Items property.
Use the pipe-bar to separate each item, for example:
= "Item A|Item B|Item C"
or
="1|2|3|4"
The Rule Builder has some functions and helpers that assist with entering values into the items property. This can be done by manually typing the items or by using Define Tables, see List, ListAll, ListAllConditional, ListAllConditionalDistinct and ListAllDistinct.
