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:
    TABLE_CustomerTable.Modify("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:
    TABLE_CalculationTable.Modify((53+29) + TAB + (83-21))
  • To modify the value of an element in a row, use the following syntax:
    TableName.ColumnName[RowIndex] = NewValue

Table or TreeView Table control based on a data file: 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 record into the linked data file, <Table>.Save must be called after <Table>.Modify.
Remarks:
  • The "Cascading input" option can be selected in the "Details" tab of the control description window.
  • Versions 19 and later
    WEBDEV - Server code The cascading input is available for Ajax Table controls based on a data file only.
