DataGrid 分页栏添加合计显示

项目中遇到在分页栏添加统计显示的需要，经过观察，可以在该栏动态添加表格来实现：

#region private void dgPjList_ItemCreated()

        private void dgPjList_ItemCreated(object sender, DataGridItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Pager && ViewState[c_DataSetName] != null)
            {
                const String c_TOTAL = "  総計 {0}件";
                DataSet dstTotal = (DataSet) ViewState[c_DataSetName];
                String strTotal = String.Format(c_TOTAL, dstTotal.Tables[0].Rows.Count);
                Table tbl = new Table();
                int intRows = 0;

                tbl.Rows.Add(new TableRow());
                tbl.Style.Add("width", "100%");
                TableRow trPager = tbl.Rows[0];
                trPager.Cells.Add(new TableCell());
                trPager.Cells.Add(new TableCell());
                trPager.Cells[0].HorizontalAlign = HorizontalAlign.Left;
                trPager.Cells[0].Wrap = false;
                trPager.Cells[0].Text = strTotal;
                trPager.Cells[1].HorizontalAlign = HorizontalAlign.Right;
                trPager.Cells[1].Wrap = false;
                e.Item.Cells[0].Wrap = false;
                intRows = e.Item.Cells[0].Controls.Count;
                e.Item.Cells[0].Controls.Add(tbl);
                for (int i = 0; i < intRows; i++)
                {
                    trPager.Cells[1].Controls.Add(e.Item.Cells[0].Controls[0]);
                }

            }
        }

        #endregion
