GridView添加统计行 ［转帖］

GridView添加统计(合计)行

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)
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;
mysum1 +=Convert .ToInt32 (myrows[2].ToString ());
mysum2 += Convert.ToInt32(myrows[3].ToString());
}
// 合计
if (e.Row.RowType == DataControlRowType.Footer)
e.Row.Cells[0].Text = "合计";
e.Row.Cells[1].Text = mysum1.ToString();
e.Row.Cells[2].Text = mysum2.ToString();
}
}
