Syntax
TableModifyLine(<Table control> , <Subscript> [, <Element column 1> [... [, <Element column N>]]])
<Table control>: Control name
Name of the control to be used. This control can correspond to:
  • a Table control.
  • a TreeView Table control.
If this parameter corresponds to an empty string (""), the control to which the current event belongs will be used.
<Subscript>: Integer
Subscript of row to modify. The subscript of first row is set to 1.
Subscript equal to -1The current row is modified. No effect if no row is selected.
Subscript greater than the number of control rowsA WLanguage error occurs.
<Element column 1>: Optional character string
First element of the modified row. The value of this element replaces the existing value. Each element corresponds to a column. Each type of modified element must be compatible with the type of relevant column.
If none of the <Column element X> parameters are specified, function TableModifyLine has no effect.
<Element column N>: Optional character string
Nth element of the modified row. The value of this element replaces the existing value. Each element corresponds to a column. Each type of modified element must be compatible with the type of relevant column.
If none of the <Column element X> parameters are specified, function TableModifyLine has no effect.
Remarks

Use conditions

TableModifyLine can be used on:
  • a browsing or memory control,
  • a single-selection or multi-selection control.

Characteristics of row elements

  • To modify the value of an element in a row, use the following syntax:
    ChampTable.NomColonne[IndiceLigne] = NouvelleValeur
  • If an element corresponds to the calculation result, the numeric expression must be enclosed in brackets.
    For example:
    TableModifyLine(TABLE_TableCalcul, (53+29),(83-21))

Browsing Table or TreeView Table control: Modifications in the linked data file

  • If the cascading input is enabled, the data file linked to the control is automatically modified when the user goes to the next row.
  • If the cascading input is not enabled, the data file linked to the control is not modified. To write the contents of the modified row to the data file linked, it is necessary to use function TableSave after function TableModifyLine.
Remarks:
  • The "Cascading input" option can be selected in the "Details" tab of control description.
  • Java The cascading input is not available for browsing Table controls with direct access. This option is available for the memory Table controls and for the browsing Table controls loaded in memory.

Modifications performed in a browsing Table or TreeView Table control

To modify a row in a browsing Table or TreeView Table control, we advise you to:
  • modify the record in the data file with HModify,
  • use the function TableDisplay to re-update the control .
WINDEVJava

TableModifyLine function and Modified property

TableModifyLine has no influence on the Modified property. The Modified property is used to know if the current row has been directly modified by the user (direct input in the control).
