FoxPro/Visual FoxPro - color de fila en grilla

chic@s necesito cambiar el color de una fila de la grilla osea es un form donde filtrop articulos x proveedor para saber el stock de cada uno, pero cada art tiene un campo stock minimo entonces verifico si el stockminimo es mayor a el stock entonces pinto la fila de rojo sino que sea de color negro ,me funciona con un registro pero cuando son mas no.
yo hago esto:
local costotot,costo2 as currency
store 0 to costo2
*CREATE CURSOR reporte(rubro c(4),subrubro c(4),subrubro2 c(4),subrubro3 c(4),codigo c(16),descripcio c(60))
*SELECT grilla
*set filter to
*ZAP
Thisform.grd.recordsource = " "
* ###
* Armar las condiciones que van sobre artic.
lccond=""
if!(empty(thisform.codart))
lccond=lccond + " A.codigo='"+alltrim(thisform.codart)+"'.AND."
endif
if!(empty(thisform.fabrica))
lccond=lccond + " A.fabri_rev='"+alltrim(thisform.fabrica)+"'.AND."
endif
if!(empty(thisform.familia))
lccond=lccond + " A.familia='"+alltrim(thisform.familia)+"'.AND."
endif
if!(empty(thisform.rubro))
lccond=lccond + " A.rubro='"+alltrim(thisform.rubro)+"'.AND."
endif
if!(empty(thisform.subrubro))
lccond=lccond + " A.subrubro='"+alltrim(thisform.subrubro)+"'.AND."
endif
if!(empty(thisform.subrubro2))
lccond=lccond + " A.subrubro2='"+alltrim(thisform.subrubro2)+"'.AND."
endif
if!(empty(thisform.subrubro3))
lccond=lccond + " A.subrubro3='"+alltrim(thisform.subrubro3)+"'.AND."
endif
if!(empty(thisform.proveedor))
lccond=lccond + " A.proveedor='"+alltrim(thisform.proveedor)+"'.AND."
endif

IF !EMPTY(lccond)
lccond = LEFT(lccond,len(lccond)-5)
lccond = " AND " + lcCond
ENDIF
*lcEx = "SET FILTER TO " + lccond

lcfiltro = ""
lcsq = ""

endscan

utiliza este comando
SETALL

Form1.Grid1.SetAll("BackColor", RGB(255, 0, 0), "Column")

del ejemplo que adjunto, pinta en rojo las filas que tinen marcado el urgente y las modificaciones son en linea, puedes anidar mas condicionales si te es necesario.

thisform.grdSim_itm.setall("dynamicforecolor","iif(simurg=.t.,rgb(255,0,0),rgb(0,0,0))","column")
