Hi Juan,
Is it possible to use Init Event to set Column's property? In this case all subclasses of this grid will set this property correctly.
For example:
PROCEDURE Init
THIS.Column1.BackColor=YourColor
ENDPROC
Also you can set this property for all columns:
PROCEDURE Init
LOCAL loColumn
FOR EACH loColumn in THIS.Columns
loColumn.BackColor=YourColor
ENDFOR
ENDPROC
