LISTBOX MOVED ROW NUMBER ( {* ;} object ; oldPosition ; newPosition )

Parameter	Type	Description
*	Operator	If specified, object is an object name (string) If omitted, object is a variable

Description

The LISTBOX MOVED ROW NUMBER command returns two numbers in oldPosition and newPosition indicating respectively the previous position and the new position of the row moved in the list box, specified by the object and * parameters.

Note: You can only move rows in array type list boxes.

If you pass the optional * parameter, you indicate that the object parameter is an object name (string). If you do not pass this parameter, you indicate that the object parameter is a variable. In this case, you pass a variable reference instead of a string. For more information about object names, refer to the Object Properties section.

This command must be used with the form event On Row Moved (see the Form event code command).

Note: This command does not take into account any hidden/displayed states of list box rows.
