Not sure I follow you explanation. What I understand is that you want the area containing the detail gird to be of one color, and the data rows of the detail grid to have a gradient style. You already know how to set the data rows. Have you tried setting the detail grid margins BackColor properties?
detailGridTemplate1.SideMargin.BackColor = Color.DeepSkyBlue;
detailGridTemplate1.TopMargin.BackColor = Color.DeepSkyBlue;
detailGridTemplate1.BottomMargin.BackColor = Color.DeepSkyBlue;
