Syntax

Displaying a Table or TreeView Table control from a specified row Hide the details

TablePosition(<Table control> , <Subscript>)
<Table control>: Control name

If this parameter corresponds to an empty string (""), the control used will be the Table control to which the current event belongs.
<Subscript>: Integer

The last row is selected by default if this parameter is greater than the number of rows found in the Table control (returned by TableCount).

Remarks

Use conditions

TablePosition 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, TablePosition tries to display as many rows as possible in the control.
TablePosition 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 TablePosition function

TablePosition does not modify the current row (i.e. the row selected with the selection bar).
Therefore, if the Table control has focus when TablePosition 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>).
Reports and Queries

Browsing Table control: limitations of TablePosition

TablePosition 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"

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