Remarks

Use conditions

TableModifyLine 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.
Reminder: Multi-selection is not available for Table controls in "Server" mode.

This function is available for Table controls in "Server" and "Server + AJAX" mode, and for TreeView Table controls.

This function is available for Table controls in "Browser" mode only.

The TreeView Table control is not available.

Table controls based on a data file are not available in edit mode. TableModifyLine cannot be used on Table controls based on a data file.

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:
TableModifyLine(TABLE_CalcTable, (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, TableSave must be used after TableModifyLine.

Remarks:

The "Cascading input" option can be selected in the "Details" tab of the control description.
The cascading input is not available for Table controls with direct access to the data source. This option is only available on Table controls populated programmatically or with in-memory data source.
The cascading input is available for Ajax Table controls based on a data file only.

Changes in a Table or TreeView Table control based on a data file

To modify a row in a Table or TreeView Table control based on a data file, we advise you to:

modify the record in the data file with HModify,
use TableDisplay to refresh the control.

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).
