We know that:
thisform.grid1.column1.backcolor = 0

changes the color property in column1 of the grid;

but if we have 100 cols

n = 100
m = 0
for i = 1 to n
m = m + 1
**THE PROBLEM:(these two didn't work)
*thisform.grid1.column(m).backcolor = 0
*thisform.grid1.column&m.backcolor = 0
endfor

how can it be done?

Thanks
