No matter what I try I can not get the grid lines to be any color other than light gray. I have tried many combinations including the below to no avail...

            grdWork.DisplayLayout.Appearance.ThemedElementAlpha = Infragistics.Win.Alpha.Transparent
            grdWork.DisplayLayout.Appearance.BorderColor3DBase = Color.Red
            grdWork.DisplayLayout.Appearance.BorderColor = Color.Red
            grdWork.DisplayLayout.Appearance.BorderColor2 = Color.Red

What am I missing?
