Understanding list dialogs
List dialogs are dialogs controlling a list of records rendered in a list container such
as TABLE, TREE or SCROLLGRID.
Genero provides the DISPLAY ARRAY and INPUT ARRAY list dialogs
to control a list of records that are defined in a program
array.
Note: The
DISPLAY ARRAY and INPUT ARRAY dialogs can use dynamic or
static arrays. Static arrays are supported for backward compatibility. Consider using dynamic arrays
in new implementations.A DISPLAY ARRAY handles by default a read-only list. However, you can implement
modification triggers, to let the end user
append, modify and delete rows.
An INPUT ARRAY dialog allows immediate data modification: The rows are editable
by default.
The topics in this chapter are common to all list dialogs.
The form must define a list container to display the records, it can be one of the following:
Eventually, the list dialog can control a plain grid with basic form fields. In this case, only one record will be displayed at a time, but list navigation is still available.
