<Looper>.Sort (Function)

In french: <Zone répétée>.Trie

Allows sorting a Looper control according to one or more of its attributes.

Example

// Tri selon un des attributs du champ Zone répétée choisi dans un champ Sélecteur
SWITCH SEL_SELECT1
	CASE 1: ZR_Client.Trie("NOM")
	CASE 2: ZR_Client.Trie("SOCIETE")
	CASE 3: ZR_Client.Trie("VILLE")
END

Syntax

Sorting a Looper control according to a list of attributes Hide the details

<Result> = <Looper control>.Sort(<List of attributes>)

<Result>: Boolean

True if the sort was performed,
False otherwise.

<Looper control>: Control name

Name of the Looper control to be used.

<List of attributes>: Character string

Name of the attributes according to which the Looper control will be sorted (up to 10 attributes). This character string must have the following format:
"[<Sens>]<Attribut 1>" + TAB + "[<Sens>]<Attribut 2>" + TAB + ...
with:
: sorting direction (optional), can take the following values:
"+": sorting will be ascending (default value).
"-": sorting will be in descending order.
: name of the attribute used for sorting.

Remarks

Use conditions

<Looper>.Sort can be used on:

a Looper control based on a data file,
a Looper control populated programmatically.

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 bound to a data source and using a programmed iteration

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

Looper control bound to a data source,
Looper control that uses Browse programmatically ("Content" tab in the control description window).

To change the display order of a Looper control with programmed iteration, 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, ...).
