Hi,

Yes, it is possible. :)

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridOverride ov = layout.Override;

            TextOrientationInfo textOrientationInfo = new TextOrientationInfo(45, TextFlowDirection.Horizontal);
            ov.ColumnHeaderTextOrientation = textOrientationInfo;
        }
