I finally figured this out. I was 'overwriting' the column backcolor values that I was setting in my form with the following code that I had put in my sub-classed grid:

This.SetAll( 'DynamicForeColor', ;
'IIF( RECNO( This.RecordSource ) = This.p_nRecNo, RGB( 0, 0, 128 ), RGB( 0, 0, 0 ) )', 'COLUMN' )
This.SetAll( 'DynamicBackColor', ;
'IIF( RECNO( This.RecordSource ) = This.p_nRecNo, RGB( 0,255,255 ), RGB( 255, 255, 255 ) )', 'COLUMN' )

I guess I don't understand completely the differences between the BackColor and DyanamicBacakColor properties.
