There is no FixedColumnsBackColor property. You need to cycle through each column that is fixed, and change the BackColor for each one. If you permit the user to change which columns are fixed, you need to subscribe to the required events (e.g. FixedChanged on the Column) to toggle the BackColor.
As for the StyleSheet, it is not a bug, that’s the way it is.
