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)

ROWBOUND

Usage

The ROWBOUND is typically used in a DISPLAY ARRAY or INPUT ARRAY dialog action handler, when the action depends from the row context. The actions marked with this attribute will be automatically enabled/disabled according the current row existence, and rendered in a special way according to the front-end platform standards.

Important: This feature is only for mobile platforms.

The ROWBOUND attribute was mainly introduced for mobile applications, when using a TABLE container to get a list view: Actions marked with this attribute will be rendered in a native manner on the mobile device.

If a default action view is displayed for the action, it will be automatically hidden when no current row context is available.

This attribute can only be specified in a list handling dialog, 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.

Default actions such as the delete action when using an ON DELETE modification trigger will automatically get the ROWBOUND attribute, to be available only when at least one row exists in the list. Therefore, the ROWBOUND attribute cannot be specified for such DISPLAY ARRAY modification triggers.

Example

DISPLAY ARRAY ...
   ...
   ON ACTION print ATTRIBUTES(ROWBOUND)
      CALL print_customer_info(arr_curr())
   ...
