Hi Allon,
Thanks for your update.
The link provided in my previous update works fine. Regarding the issue with backcolor, if you are setting backcolor for certain rows in grid through PrepareViewStyleInfo event, then you cannot overwrite those cells with other colors through some other means. The PrepareViewStyleInfo event get triggered each time the style setting of a cell is queried.
One thing you can try to achieve setting different color at runtime is, supply the colors through custom properties and set them in PrepareViewStyleInfo event.
Please refer to the following sample in which this has been achieved. By clicking the button, you can apply different set of colors.
