ROWBOUND action attribute
The ROWBOUND attribute defines if the action is related to the row
context of a record list.
Syntax
(only in action handlers of record list dialog)
ROWBOUNDUsage
The ROWBOUND attribute is to be used in a DISPLAY ARRAY or
INPUT ARRAY dialog action handler, when the action depends on the row context.
Actions marked with this attribute will be automatically enabled/disabled, based on current row
existence.
Rowbound action views can be accessed with the three-dot button on the right of
TABLE, TREE and SCROLLGRID rows.
If the action is disabled, the corresponding rowbound action view of the three-dots button will not be displayed.
The ROWBOUND attribute can only be specified in a list handling dialog
(INPUT ARRAY or DISPLAY ARRAY), as action attribute in the
ATTRIBUTES() clause of ON ACTION handlers, and applies to the
actions defined by the current dialog in the current window.
Automatic update and delete actions of INPUT
ARRAY, as well as actions created by ON UPDATE and ON
DELETE modification trigger in DISPLAY ARRAY, are implicitly rowbound
actions. Such actions must be available only when at least one row exists in the list. Therefore,
the ROWBOUND attribute cannot be specified in DISPLAY ARRAY
modification triggers.
The main purpose of the ROWBOUND attribute is to have the corresponding action enabled and disabled
automatically by the runtime system, depending on the existence of a row. The default decoration of
such action is front-end platform driven and is the consequence of using the
ROWBOUND action attribute. A DISPLAY ARRAY or INPUT
ARRAY can be used with a plain form that show a single row at a time. The rowbound actions
can also be used in such case, using form buttons as action views for example. These buttons will be
automatically enabled/disabled according to the list content.
