以上列表中运用的都是基本的东东： 1.多表头； 2.按值改变行颜色； 3.分页码 代码： AndyGridViewTHeaderHepler.cs //-----------------------------------------------------------------------------------

// Description: 动态生成复合表头帮助类
// 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(',').
// 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
// 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
// 三行时请注意：列头要重复

运用时代码如下：
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
SQLServerDAL.AndyGridViewTHeaderHepler dHelper = new SQLServerDAL.AndyGridViewTHeaderHepler();
string header = "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"; //---------------------------------------------------------------------------------------
// 加载 gridview Header 的样式
//---------------------------------------------------------------------------------------
e.Row.CssClass = GridView1.HeaderStyle.CssClass; dHelper.SplitTableHeader(e.Row, header);
}
}
