Hi Michael,
The this.gridDataBoundGrid1.BaseStylesMap["Column Header"].StyleInfo.BackColor property works fine.
The GridBoundColumn.HeaderText property of a column must be used to change the column header text. If you did not add GridBoundColumns, then GridDataBoundGrid.Binder.InternalColumns HeaderText property must be used.
Please refer the attached sample.
Best Regards,
Calvin.
