Come on. The method itself is named ParentChanged.

 Procedure parentchanged
    * Parent degistiginde normal olarak tableupdate() olacak veya revert
    * Boylece select-sql dogru sonuc verecek
    Tableupdate(2,.T.,'FatParent')
    Tableupdate(2,.T.,'FatChild')
    External Array arrToplam
    Select Sum(Fiyat*Miktar), Sum(Miktar) ;
      from FatChild ;
      where ParId = FatParent.PkId ;
      into Array arrToplam
    Thisform.txttoplam.Value = Iif(_Tally=0,0,arrToplam[1,1])
    Thisform.txtmiktar.Value = Iif(_Tally=0,0,arrToplam[1,2])
  Endproc

Doesn't method name and code together say "when parent changes you would etiher do tableupdate or revert and thus select-sql would give correct result".
