Displayed line number
Displayed line number -> Function result
| Parameter | Type | Description | |
|---|---|---|---|
| Function result | Longint | ← | Number of row being displayed |
This command is not thread-safe, it cannot be used in preemptive code.
Description
The Displayed line number command only works with the On Display Detail form event. It returns the number of the row being processed while a list of records or list box rows is displayed on screen. If Displayed line number is called other than when displaying a list or a list box, it returns 0.
In the case of a list of records, when the displayed row is not empty (when it is linked to a record), the value returned by Displayed line number is identical to the value returned by Selected record number.
Like Selected record number, Displayed line number starts at 1. This command is useful if you want to process each row of a list form or list box displayed on screen, including empty rows.
Example
This example lets you apply an alternating color to a list form displayed on screen, even for rows without records:
//List form method
If(Form event code=On Display Detail)
If(Displayed line number% 2=0)
//Black on white for even row text
OBJECT SET RGB COLORS([Table 1]Field1;-1;0x00FFFFFF)
Else
//Black on light blue for odd row text
OBJECT SET RGB COLORS([Table 1]Field1;-1;0x00E0E0FF)
End if
End if
