Characteristics of row elements

  • To modify the value of an element in a row, use the following syntax:
    TableControl.ColumnName[RowIndex] = NewValue
  • If an element corresponds to the calculation result, the numeric expression must be enclosed in brackets.
    For example:
    TABLE_CalculationTable.ModifyLine((53+29),(83-21))

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 content of the modified row to the linked data file, <Table>.Save must be used after <Table>.ModifyLine.
Remarks:
  • The "Cascading input" option can be selected in the "Details" tab of the control description.
  • WEBDEV - Server code The cascading input is available for Ajax Table controls based on a data file only.
