    if (e.Column.AbsoluteIndex == dgViewMaster.FocusedColumn.AbsoluteIndex)

        e.Appearance.Font = new Font(AppearanceObject.DefaultFont, FontStyle.Bold);

    else
    {
        e.Appearance.Font = AppearanceObject.DefaultFont;
        e.Appearance.ForeColor = SystemColors.WindowText;

    e.Appearance.DrawString(e.Cache, e.Column.GetTextCaption(), e.Info.CaptionRect);
    e.Info.InnerElements.DrawObjects(e.Info, e.Info.Cache, Point.Empty);
