Don,

It is tricky but the statement I use when I attempt to change the property:
ThisForm.grdFiles.SetAll("DynamicBackColor",; "IIF(files.status=1,RGB(192,192,192),RGB(255,255,255))","column")

is the exact one I use in the INIT method of the grid and it works fine, I just can't change the property after it is set in the init method, but I will keep playing with it as I am seriously annoyed at it !

Thanks !
