Dev控件GridControl和TreeList的数据导出操作

导出pdf格式出现乱码时可以在main 方法中添加如下代码：
DevExpress.Utils.AppearanceObject.DefaultFont = new System.Drawing.Font("宋体", 9);
  1 /// <summary>
  2     /// 数据导出
  3     /// </summary>
  4     public class DataExport
  5     {
  6         /// <summary>
  7         /// 导出GridConrol中的数据
  8         /// </summary>
  9         /// <param name="gridControl"></param>
 10         public static void GridControlExport(GridControl gridControl)
