首先捕获"EndSorting"事件，然后在其中加入以下代码：

  private void gridView_EndSorting(object sender, EventArgs e)
        {

            Color clr = gridView.Appearance.Row.BackColor;
            foreach (DevExpress.XtraGrid.Columns.GridColumn dc in gridView.Columns)
            {
                if (dc.VisibleIndex == gridView1.SortedColumns[0].VisibleIndex)
                {
                    dc.AppearanceCell.BackColor = Color.Red;
                }
                else
                {
                    dc.AppearanceCell.BackColor = clr;
                }
            }
        }

其中的"gridView"是"DevExpress.XtraGrid.Views.Grid.GridView"类型实例
