Remarks

Use conditions

<Table>.Position can be used on:

a browsing or memory control,
a single-selection or multiselection control.

Displaying a row in first position (syntax 1)

The row displayed in first position may differ from the requested one. Indeed, <Table>.Position tries to display as many rows as possible in the control.

<Table>.Position will display the specified row only if this row is followed by a sufficient number of non-empty rows. In the following example, the "Durand" row cannot be displayed at the beginning of Table control.

Selection bar and <Table>.Position function

<Table>.Position does not modify the current row (i.e. the row selected with the selection bar).

Therefore, if the Table control has focus when <Table>.Position is run, the current row will have to be visible at the same time as the specified row. If the current row and the specified row cannot be displayed at the same time, the content of the control will be displayed from the current row (and not from the row specified by <Subscript>).

Browsing Table control: limitations of <Table>.Position

<Table>.Position does not operate with browsing Table controls in "manual" mode that use a bouncing scrollbar ("Proportional scrollbar" not checked in the "Details" tab of the control description).

Reminder:

A browsing Table control in "manual" mode is a control that is linked by programming to a data file.
A bouncing scrollbar allows you to move the scrollbar by keeping the mouse button pressed on the scrollbar box or by keeping one of the arrow keys down.

Event "Entry in edit in a row of"

<Table>.Position does not force the execution of the event "Entry in edit in a row of".
<Table>.Position cannot be used in the event "Entry in edit in a row of" of the control (the result returned is incorrect).
