I think you still don't understand what I mean.
My NODES(rows) are drawn by the stylist. As soon as I set an individual CellBackColor on a column, that cell in that column is no longer drawn by the stylist DrawRow method but further more has the color that it was just set to. This is the expected bahavior. However, what I want to do now is to "unset" that CellBackColor again, so that cell is drawn again by the DrawRow method in the stylist.
Does that make sense?
