The Customize List Box Value Dialog

The Customize List Box Value dialog can be displayed by clicking on the Customize push button in the Properties section of the Edit List Box dialog. This dialog presents additional attributes of a list box related to its data value. The dialog consists of one section, Validation.

Validation Section

This section presents the validation attributes for list boxes.

Blank is $Null

This field determines if blank values in the list box should be translated to the Zim null value $Null. If this field is selected, this translation  occurs. Otherwise, it does not.

Value Required

This field sets the "required" attribute for the list box. The values are "No", "Yes" and "Immediate". "No" means that blank list items are accepted. "Yes" means that a non-blank list item must be selected before a FORM INPUT "transmit" action can occur. "Immediate" means that a non-blank list item must be selected before the list box can lose the input focus.

Error Message

This field contains the message to display in the message field in the form (if one exists) when the entered data fails the Validation Rule.
