Remarks

Use conditions

<Looper>.Sort can be used on a browsing or memory Looper control.

This function is not available for the Linear Looper controls. This function is available for Looper controls in browser mode only.

This function is available for Looper controls in Ajax mode, Looper controls in classic mode and Linear Looper controls.

Sort

The sort will be taken into account during the next addition of a row into the Looper control (<Looper>.Add, <Looper>.AddLine, <Looper>.Insert and <Looper>.InsertLine).

Looper linked to a data source and using a programmed browse

<Looper>.Sort does not operate on a Looper control with the following characteristics:

Looper control linked to a data source,
Looper control that uses Programmed browse ("Content" tab in the control description window).

To change the display order of a Looper control with programmed browse, you must adapt the code found in the different read processes of the Looper control (process for reading the first one, the next one, the previous one, ...).
