<Element index>: Optional integer

If this parameter:
is not specified or if it is set to -1, the current element is modified. ListModify has no effect if there is no current element.

Remarks

Multi-selection List Box control

If one or more elements are selected in the List Box control, ListModify deselects no element.

Modified element

When modifying an element containing an invisible value (specified by gStoredValue), gStoredValue must be re-used. Otherwise, this invisible value will be lost during the modification.

For example:

adding "MyElement":

ListAdd(COMBO_MaCombo, "MonElément" + gStoredValue("1"))

modifying "MyElement":

ListModify(COMBO_MaCombo, "MonNouvelElément" + gStoredValue("1"))

To modify an element in a Table control, use TableModify.
ListModify can be used on a "Combo Box" table column.
