GriView 添加合并行 1
前提：设置属性ShowFooter="True"
方法一：使用SQL查询统计出合计值，在绑定GridView时让其结果赋于一个DataTable(全局变量)，然后在RowDataBound事件中
if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[0].Text = "合计"; e.Row.Cells[3].Text = dtSum.Rows[0][0].ToString(); e.Row.Cells[4].Text = dtSum.Rows[0][1].ToString(); e.Row.Cells[5].Text = dtSum.Rows[0][2].ToString(); e.Row.Cells[6].Text = dtSum.Rows[0][3].ToString(); e.Row.Cells[7].Text = dtSum.Rows[0][4].ToString(); e.Row.Cells[8].Text = dtSum.Rows[0][5].ToString(); e.Row.Cells[9].Text = dtSum.Rows[0][6].ToString(); e.Row.Cells[10].Text = dtSum.Rows[0][7].ToString(); e.Row.Cells[11].Text = dtSum.Rows[0][8].ToString();
}
其中dtSum是那个全局DataTable，在绑定GridView同时将SQL查询的结果赋给它；效果如下：
方法二、直接把对应列每一行的值相加(不做数据查询，在RowDataBound事件中运算)
//注：必须先将ShowFooter属性设为true
int mysum1 = 0; 
int mysum2 = 0; protected void GridList_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow )
{ DataRowView myrows=(DataRowView)e.Row.DataItem;
//要统计计算和的列 mysum1 +=Convert .ToInt32 (myrows[2].ToString ()); mysum2 += Convert.ToInt32(myrows[3].ToString());
} // 合计 if (e.Row.RowType == DataControlRowType.Footer) {
//显示统计数的位置 e.Row.Cells[0].Text = "合计"; e.Row.Cells[1].Text = mysum1.ToString(); e.Row.Cells[2].Text = mysum2.ToString(); } }
