When the user clicks in a vertical scroll bar, nothing happens unless you have scripts that change the scroll bar’s Position property. For the scroll bar arrows, use the LineUp and LineDown events; for clicks in the scroll bar background above and below the thumb, use the PageUp and PageDown events; for dragging the thumb itself, use the Moved event.
This code in the LineUp event causes the thumb to move up when the user clicks on the up arrow of the vertical scroll bar and displays the resulting position in the StaticText control st_1:
IF This.Position < This.MinPosition + 1 THEN
This.Position = MinPosition
ELSE
This.Position = This.Position - 1
END IF
st_1.Text = "LineUp " + String(This.Position)
