TableModify(COL_LASTNAME, "Moore", 5)
TableModify(<Table control> , <Row> [, <Index>])
<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 used will be the control to which the current event belongs.
<Row>: Character string
Modified row replacing the specified row. This row has the following format:
<Element of column 1> + TAB + <Element of column 2> + TAB + ...
<Index>: Optional integer
Index of the row to be modified. The value of first row is set to 1.
Index not specified or equal to -1The current row is modified. This constant has no effect if no row is selected.
Index greater than the number of control rowsA WLanguage error occurs.

Use conditions

TableModify can be used on:
  • a Table or TreeView Table control based on a data file.
  • a Table or TreeView Table control populated programmatically.
  • a single-selection or multi-selection control.

Row characteristics

  • Each row element is changed into the type of the associated column.
  • If one of the elements corresponds to an empty string ("") or to 0 (depending on the column type), its value will be overwritten.
    For example:
    TableModify(TABLE_CustomerTable, "Moore" + TAB + "Peter" + TAB + "" + ...
    TAB + "06/21/72")
  • If an element corresponds to the calculation result, the numeric expression must be enclosed in brackets.
    For example:
    TableModify(TABLE_CalcTable, (53+29) + TAB + (83-21))
  • To modify the value of an element in a row, use the following syntax:
    TableName.ColumnName[RowIndex] = NewValue
