>I hve tried DynamicBackColor/DynamicForeColor but in this way it is possible only two colours I need at least 10 colours. The colour of the cell is controled by a bdf field

You can have as many colors as you want.

* grid Init
* nColor is a column in the grid recordsource with stored color for that row
WITH This.Column2
  .DynamicBackColor = "IIF( Empty(nColor), RGB(128,128,128), nColor)"
  * or
  .DynamicForeColor = "IIF( Empty(nColor), RGB(128,128,128), nColor)"
ENDWITH

You can set those properties in the Properties Sheet, as well.
