How do I change the border color on a radSplitButton? I'm using
btnUser.DropDownButtonElement.ButtonSeparator.BorderColor = Color.FromArgb(255, 190, 106)
btnUser.DropDownButtonElement.ActionButton.BorderElement.ForeColor = Color.FromArgb(255, 190, 106)
but it only changes part of the border color. The left and right borders are unchanged.
