Remarks

Characteristics of column elements

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

Browsing table: Modifications in the linked data file

If the cascading input is enabled, the data file linked to the browsing Table control is automatically modified when the user goes to the next column.
If the cascading input is not enabled, the data file linked to the browsing Table control is not modified. To write the record into the data file, <Table>.Save must be run after <Table>.ModifyColumn.
Reminder: The "cascading input" option can be selected:
  • When creating a Table control.
  • In the "Details" tab of the description window of Table control in the window editor.

Modifications performed in a browsing Table control

To modify a column in a browsing Table control, we advise you to:

<Table>.ModifyColumn function and ..Modified property

<Table>.ModifyColumn has no influence on ..Modified. ..Modified is used to find out whether the current column was directly modified by the user (direct input in the Table control).
