grid.net在asp.net中查看页脚总数

Question

  

可能重复：
  gridview with footer row total in the final page of the grid

protected void inderGrid_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            decimal rowTotal = Convert.ToDecimal
            (DataBinder.Eval(e.Row.DataItem, "DC_No_Decimal"));
            //grdTotal = grdTotal + rowTotal;
            grdTotal += rowTotal;
        }
        if (e.Row.RowType == DataControlRowType.Footer)
        {
            Label lbl = (Label)e.Row.FindControl("lblTotal");
            e.Row.Cells[3].Text = grdTotal.ToString("c");
            //lbl.Text = grdTotal.ToString("c");
        }       
    }

这是我在行gridview rowdatabound事件中的代码，这里我得到每个页面的总数而不是得到每个页面的总数我想在gridview页脚的最后一页得到任何一个帮助
