 前台：设置gridview的ShowFooter="True" ，否则默认表头为隐藏的！ 

后台代码

RowDataBound事件  

 private double sum = 0;
    protected void GetAccountsOpened10_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowIndex >= 0)
        {
            sum += Convert.ToDouble(e.Row.Cells[1].Text);
        }
        else if (e.Row.RowType == DataControlRowType .Footer)
        {
            e.Row.Cells[1].Text = "total：" +sum.ToString();
       
        }
    }
