求助,关于DevExpress GridView导出到Excel的问题!!!!

设置了CustomColumnDisplayText事件后,GridView导出的数据到Excl是自定义后的数据 ,如何才能导出原始数据? 
protected void ASPxGridView1_CustomColumnDisplayText(object sender, ASPxGridViewColumnDisplayTextEventArgs e)
    {
        for (int i = 0; i < ASPxGridView1.VisibleRowCount; i++)
        {
            if (e.Column.FieldName == "品名")
            {
                var v_hash = new Hashtable();
                v_hash.Add("p1", e.GetFieldValue("入库单id"));
                v_hash.Add("p2", Q_入库日期_1.Date.ToString("yyyy-MM-dd"));
                v_hash.Add("p3", Q_入库日期_2.Date.ToString("yyyy-MM-dd"));
                v_hash.Add("p4", e.GetFieldValue("数量1"));
                v_hash.Add("p5", e.GetFieldValue("金额2"));                string v_str = "<a href='库存台账明细.aspx?%s'>%s<a>";
                v_str = Common.FormatEh(v_str,
                                        CommonWebUtil.GetUrlParams(v_hash), e.GetFieldValue("品名"));
                e.DisplayText = v_str;
            }
        }
    }
public static void GridExport(string fileName, ASPxGridViewExporter gridExporter)
    {
        XlsExportOptions ExportOptions = new XlsExportOptions
        {
            ExportMode = XlsExportMode.SingleFile,
            SheetName = "Sheet1",
            ShowGridLines = true,
            TextExportMode = TextExportMode.Text
        };        gridExporter.WriteXlsToResponse(fileName, true, ExportOptions);
    }protected void ASPxMenu1_ItemClick(object source, MenuItemEventArgs e)
    {
        switch (e.Item.Text)
        {
            case "查询":
                LoadData();
                return;
            case "清空查询":
                CommonWebUtil.清空查询(div查询);
                return;
            case "导出":
                LoadData();
                CommonWebUtil.GridExport("库存台账", ASPxGridViewExporter1);
                return;
        }
