Center a Row in Grid

Hi All,
I have a problem centering the active row in the visible part of a grid.

I use a code similar to
LOCAL;
 lnHeight AS INTEGER,;
 lnRows   AS INTEGER,;
 lnLoop   AS INTEGER


WITH oGrid
 lnHeight = .HEIGHT
 lnRows   = ROUND(((lnHeight-.HEADERHEIGHT)/.ROWHEIGHT)/2,0)
 .HEIGHT = .ROWHEIGHT+.HEADERHEIGHT

 .REFRESH()
 .HEIGHT = lnHeight
 FOR lnLoop = 1 TO lnRows-1
  .DOSCROLL(0)
 ENDFOR &&lnLoop
ENDWITH &&oGrid
this works fine as long as the grid is not in focus. If the grid is in focus and the code beyond is run, the recordpointer will move. This is not easy to trace, because the grid needs to be in focus. I figured out that the change of recordpointer happens in REFRESH(). There is no code in REFRESH() event, I've checked with a plain grid.
So I put some code in BEFORROWCOLCHANGE to stop moving of RecordPointer if the grid is centering. The movement stops, but then no centering occurs. Same happens if the stop of moving is triggered in textbox VALID()

So I look for a idea to get the thing centered with the record activated before REFRESH()

TIA
