LooperDisplay (Function)

In french: ZoneRépétéeAffiche

Refreshes the display of a RepeatString data file field from a given position: changes made to the linked data file are reflected in the RepeatString field.

Remark: The LooperDisplay function can be used on either a file or memory Looper control.

The page containing the Looper control is refreshed.

Example

// Rafraîchissement du champ Zone répétée "ZR_ZoneProduit" à partir du début du champ 
LooperDisplay(ZR_ZoneProduit, taStart)

Syntax

LooperDisplay(<Looper control> [, <Position>])

<Looper control>: Control name

Name of the Looper control to refresh.
If this parameter corresponds to an empty string (""), the Looper control to which the current event belongs is refreshed.

<Position>: Integer, character or constant (optional)

Indicates the start position for the refresh. If this parameter is not specified, the elements of the Looper control are redisplayed from the current element in the Looper control.
This parameter can correspond to:
An integer. The refresh is performed from this position. The selected row is not modified. The "Select a row" event of <Position> is run. The current element in the Looper control is the same as the current record in the data file. If this integer is invalid (outside the authorized bounds), the call to LooperDisplay triggers an error.
