Example
// Add "Moore", "Vince" and "06/21/72"
// at the end of the "TABLE_CustomerTable" control
ResAdd = TABLE_CustomerTable.Add("Moore" + TAB + "Vince" + TAB + "06/21/72")
Syntax
<Result> = <Table control>.Add([<Row>])
<Result>: Boolean
  • True if the element was added,
  • False otherwise.
<Table control>: Control name
Name of control to use. This control can correspond to:
  • a Table control.
  • a TreeView Table control.
  • Windows Mobile a Combo Box control with table.
<Row>: Optional character string
Row to add. This row has the following format:
<Element of column 1> + TAB + <Element of column 2> + TAB + ...

If this parameter is not specified, an empty row is added into the control. For a browsing control, the default values defined in the linked data file are taken into account.
Remarks

Use conditions

<Table>.Add can be used on:
  • a browsing or memory control,
  • a single-selection or multiselection control.
AndroidiPhone/iPad The TreeView Table control is not available.
AndroidiPhone/iPad The browsing Table controls are not available in edit. <Table>.Add cannot be used on a browsing Table control.

Characteristics of a row

  • Each added element is converted into the type of the relevant column.
  • To specify no value for an element, use an empty string ("") or 0 (according to the type of column). For example:
    TABLE_CustomerTable.Add("Moore" + TAB + "Vince" + 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.Add((53+29) + TAB + (83-21))

Position of added row

By default, the row is added at the end of the rows displayed by the control.
Special case:
  • If the control is sorted by <Table>.Sort, the added row is positioned in the control according to the current sort.
  • If the control is sorted by the user, the sort is ignored when inserting the row. The row is added at the end of control.
AndroidiPhone/iPad Special case:
  • If the control is sorted by <Table>.Sort, the added row is positioned in the control according to the current sort.
  • If the control is sorted by the user, the added row is positioned in the control according to the current sort.

Limits: Maximum number of rows displayed

The maximum number of rows that can be displayed in a Table or TreeView Table control is limited by the amount of available memory (theoretical maximum: 2 billion rows).
However, we do not advise you to use large Table or TreeView Table controls for performance and user-friendliness reasons (time required to fill the control for example).

Various

  • To add a row at a specific position in a Table or TreeView Table control, use <Table>.InsertLine.
  • If the added row is the first row of the control, the added row becomes the current row.
Windows Mobile

Adding rows

..NewLine is used to find out whether the current row was just created by <Table>.Add (..NewLine = True).
Windows Mobile

Cascading input

To perform a cascading input, <Table>.Add must be used in the event "Exit from a row" of the Table control:
IF TABLE_CustomerTable..NewLine THEN
TABLE_CustomerTable.Add()
END
Windows Mobile

Browsing Table or TreeView Table control: 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 row added in the linked data file, <Table>.Save must be used after <Table>.Add.
Notes:
  • The "Cascading input (Addition)" option can be selected in the "Details" tab of the control description.
Windows Mobile

Browsing Table or TreeView Table control: Adding several rows

A virtual row is created in the control whenever <Table>.Add is called in a browsing Table or TreeView Table control. The information will be saved in the linked data file only when <Table>.Save is called.
If <Table>.Add is successively called in the same process without being followed by <Table>.Save, only the FIRST call is effective (the following calls are ignored). A single row is added into the browsing Table or TreeView Table control.
Windows Mobile

Adding a record into a browsing Table control and releasing a trigger

You have the ability to release a trigger when a record is added into a browsing Table control. See the documentation about HDescribeTrigger for more details.
Windows Mobile

Browsing Table or TreeView Table control in edit

If <Table>.Add is called:
  • In a control event, the cursor is automatically positioned on the first column to edit in the added row.
  • In an event that does not belong to the control, (or in another process) ReturnToCapture must be used to resume the input in the Table or TreeView Table control.

Adding images

To add an image into a Table or TreeView Table control:
    Note: The column must be an Image column otherwise the added image will not be displayed properly.
