Description: 动态生成复合表头帮助类
20
//
相邻父列头之间用'#'分隔,父列头与子列头用空格(' ')分隔,相邻子列头用逗号分隔(',').
21
//
两行：序号#分公司#组别#本日成功签约单数 预警,续约,流失,合计#累计成功签约单数 预警,续约,流失,合计#任务数#完成比例#排名
22
//
三行：等级#级别#上期结存 件数, 重量,比例#本期调入 收购调入 件数,重量,比例#本期发出 车间投料 件数,重量,比例#本期发出 产品外销百分比 件数,重量,比例#平均值
23
//
三行时请注意：列头要重复
24

GridView中实现同行小计末行总计的报表
妙用GridView的RowCreated事件,可以实现报表中的小计和总计,减少对使用构造数据集合的依赖。现举一简单例子以便大家来探讨完善。
实现思路：1、整个报表的总计项，即第一行和最后一列的总计数量在SQL总计算；
2、每一型号则在创建Gridview时（RowCreated事件）实现；
protected void gvstatistics_RowCreated(object sender, GridViewRowEventArgs e) { string strrow = ""; string tempname = ""; if (e.Row.RowIndex >1 && this.gvstatistics.Rows.Count > 0) { tempname = gvstatistics.Rows[e.Row.RowIndex - 1].Cells[0].Text.Trim(); if (tempname != gvstatistics.Rows[e.Row.RowIndex -2].Cells[0].Text.Trim()) {//插入小结数据 DataTable dtdetail = getDetailStatistics(gvstatistics.Rows[e.Row.RowIndex - 2].Cells[0].Text.Trim());//获取数据函数 if (dtdetail.Rows.Count>0) { strrow = "</td></tr><tr><td>" + dtdetail.Rows[0][0].ToString() + "</td><td>" + dtdetail.Rows[0][1].ToString() + "</td>" + " <td>" + dtdetail.Rows[0][2].ToString() + "</td><td>" + dtdetail.Rows[0][3].ToString() + "</td>" + " <td>" + dtdetail.Rows[0][4].ToString() + "</td><td>" + dtdetail.Rows[0][5].ToString() + "</td>" + " <td>" + dtdetail.Rows[0][6].ToString() + "</td><td>" + dtdetail.Rows[0][7].ToString() + "</td>" + " <td>" + dtdetail.Rows[0][8].ToString() + "</td><td>" + dtdetail.Rows[0][9].ToString() + "</td>" + " <td>" + dtdetail.Rows[0][10].ToString() + "</td><td>" + dtdetail.Rows[0][11].ToString() + ""; gvstatistics.Rows[e.Row.RowIndex - 2].Cells[e.Row.Cells.Count - 1].Text += strrow; } } } }
这样就可以达到报表既有小计又有总计的效果，并且可以导出到Excel文件。
实现效果如下:
GridView1.ShowFooter 屬性是控制footer是否顯示的.默認值是false
如何在GridView的Footer内显示总计？
