gridview 添加汇总行 footer

//----------------------------------------------------------------------------------

添加属性 showfooter=true

找到控件的 grdList_RowDataBound 事件

protected void grdList_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
            }
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                // 添加汇总行 20130923
                //---------------------------------------------------------------------
                count1 += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "count1"));
                count2 += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "count2"));
                count3 += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "count3"));
                //---------------------------------------------------------------------
                if (CurrentUser.RegionDetailType != 1)
                {
                    e.Row.Cells[0].Text = "";
                }

            }
            // 添加汇总行 20130923
            //---------------------------------------------------------------------
            if (e.Row.RowType == DataControlRowType.Footer)
            {
                //e.Row.Cells[0].Text = "合计";
                e.Row.Cells[1].Text = "合计";
                e.Row.Cells[2].Text = count1.ToString();
                e.Row.Cells[3].Text = count2.ToString();
                e.Row.Cells[4].Text = count3.ToString();
                e.Row.Font.Bold = true;
            }
            //---------------------------------------------------------------------
        }
