You can trap what's changing in BeforeRowColChange event. Part of code related with it from one of my classes :

Lparameters nColIndex
Local llChangingRow,lnTop,lnBottom,lnMouseRowPos,lnMouseColPos
With This
  If Mdown()
    lnBottom = .Top+.HeaderHeight+.RelativeRow * .RowHeight
    lnTop = m.lnBottom - This.RowHeight
    lnMouseRowPos = Mrow(Wontop(),3)
    lnMouseColPos = Mcol(Wontop(),3)
    llChangingRow = !(Between(m.lnMouseRowPos,m.lnTop, m.lnBottom) ;
      and Between(m.lnMouseColPos,.Left,.Left+.Width))
  Else
    llChangingRow = Inlist(Lastkey(),24,5,18,3,141,145,148)
  Endif
Endwith
