Jim,
I forgot to mention 'when SetDyn()' would call the routine at each row movement. Still it works. But you might also do it :

use employee
browse fields last_name, ;
 first_name :p='!AAAAAAAAAAAAAAAAAAAAAAAA' ;
 nowait name 'myGrid' ;
 title "Employee List"
with myGrid
  .setall("DynamicBackColor","iif(recno()%2=0,rgb(255,255,0),rgb(255,255,255))","Column")
  .setall("SelectOnEntry",.f.)
  .Height = 300
  .Width = 200
  .Top = 100
endwith
