Hi, Johan
Thanks a lot for your reply.
I have successfully implemented simple alternating colour banding in previous projects (sort of Red - Blue - Red - Blue - etc) based on row number only. If row number is even, then red. If row number is odd, then blue.
But this problem is more complex and I have no idea how to solve it.
To answer your questions:
1. User will not be required to do any sorting. Sorting has already been done by my query.
2. I prefer to use 2 colours only (say red and blue). Too many colours can be ugly.
Hope this can help.
Best Regards,
Leon
