Hi Rich,
If you are using Office 2003 Visual Style for GroupBar, with stacked mode set to true. you could change the headerBackColor as follows:
Office2003Colors.GroupBarHeaderColorDark = Color.Red;
Office2003Colors.GroupBarHeaderColorLight = Color.White;
If you are using default Visual Style, you could simply use HeaderBackColor property to change
I have attached a sample that shows this completely.Please refer to it and let me know if I have missed anything
Regards,
Mano
