Syntax

Moving to a specific position Hide the details

<Result> = <Looper control>.MoveLine(<Index of row to move> , <Destination row index> [, <Operation to perform>])

<Result>: Integer

New index of the row that was moved.

<Looper control>: Control name

Name of the Looper control to be used.

<Index of row to move>: Integer

Position of the row to move. This position must be included between 1 and the number of rows found in the control (returned by <Looper>.Count or Count for example).
To move the row that is currently selected, use the rowSelected constant.

<Destination row index>: Integer

New row position. This position must be included between 1 and the number of rows found in the control (returned by <Looper>.Count or Count for example). A fatal error occurs if this parameter is not valid.
To handle the row currently selected, use the rowSelected constant.

<Operation to perform>: Optional Integer constant (or combination of constants)

Change of position that will be performed for the row:
amDisplayDestination The modified row is displayed in the Looper control. If necessary, an automatic scroll of rows is performed to display the modified row. The selected row (selection bar) is not modified.
This constant can be combined with the amMove and amSwap constants.
amMove
(default value) The row is moved to the index of the destination row.
amSwap The source row and the destination row are swapped.

Moving relatively to the current position Hide the details

<Result> = <Looper control>.MoveLine(<Index of row to move> , <Relative move> [, <Operation to perform>])

<Result>: Integer

New index of the row that was moved.

<Looper control>: Control name

Name of the Looper control to be used.

<Index of row to move>: Integer

Position of the row to move. This position must be included between 1 and the number of rows found in the control (returned by <Looper>.Count or Count for example).
To move the row that is currently selected, use the rowSelected constant.

<Relative move>: Integer constant

Used to move or a swap to a position relative to the index of the row to move.
amFirst Moves the row to first position.
amLast Moves the row to last position.
amNext Moves the row one position to the bottom.
amNextPage Moves the row one page to the bottom (a page corresponds to the number of rows that can be simultaneously displayed in the Looper control).
amPrevious Moves the row one position upwards.
amPreviousPage Moves the row one page to the top (a page corresponds to the number of rows that can be simultaneously displayed in the Looper control).

If this parameter is invalid (amPrevious used on the first row of the Looper control for example), the row is moved "to the nearest" position.

<Operation to perform>: Optional Integer constant (or combination of constants)

Change of position that will be performed for the row:
amDisplayDestination The modified row is displayed. If necessary, an automatic scroll of rows is performed to display the modified row. The selected row (selection bar) is not modified.
This constant can be combined with the amMove and amSwap constants.
amMove
(default value) The row is moved to the index of the destination row.
amSwap The source row and the destination row are swapped.

Remarks

Use conditions

<Looper>.MoveLine can be used on:

a Looper control with in-memory data source,
a Looper control populated programmatically.

This function is not available for 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.

Multi-selection Looper

If <Looper>.MoveLine is used on a multi-selection Looper control:

when moving a row (amMove constant): all selected rows will be moved.
when swapping rows (amSwap constant): only the first row will be swapped.
the rowSelected constant cannot be used. Otherwise, a fatal error occurs and no row will be moved.

Handling errors

Caution: <Looper>.MoveLine returns no error code. To determine if this function has generated an error, use ErrorInfo with the errMessage constant.
