這個(gè)章節(jié)內(nèi)容詳細(xì)說(shuō)明《DevExpress開(kāi)發(fā)教程之報(bào)表打印設(shè)計(jì)實(shí)現(xiàn)篇》中的關(guān)鍵代碼部分、簡(jiǎn)單的設(shè)計(jì)和打印應(yīng)用。

 1、DevExpress中可以通過(guò)report.RunDesignerDialog或者report.RunDesigner來(lái)設(shè)計(jì)報(bào)表，這里沒(méi)有使用這兩個(gè)方法來(lái)實(shí)現(xiàn)報(bào)表設(shè)計(jì)功能，而是使用第一章中的自定義的DesignReportForm來(lái)實(shí)現(xiàn)（實(shí)際上相同，但自定義可以控制其他如根據(jù)權(quán)限顯示等內(nèi)容）。

 2、DesignReportForm非常簡(jiǎn)單，就是把DesignReportControl，DesignToolBar和DesignFormattingToolBar拼湊在一起，它們共同關(guān)聯(lián)designReportControl1.DesignPanel。

 3、現(xiàn)在設(shè)計(jì)一個(gè)簡(jiǎn)單的DataSet，內(nèi)容如下：

DataSet ds = new DataSet("DeliveryDataSet");
            DataTable dtDelivery= new DataTable("Delivery");
            {
                dtDelivery.Columns.Add("BillId", typeof(string));
                dtDelivery.Columns.Add("ManualId", typeof(string));
                dtDelivery.Columns.Add("BillDate", typeof(DateTime));
                dtDelivery.Columns.Add("CustomerId", typeof(string));
                dtDelivery.Columns.Add("WarehouseId", typeof(string));
                dtDelivery.Columns.Add("Maker", typeof(string));
                dtDelivery.Columns.Add("Remark", typeof(string));
                {
                    DataRow row = dtDelivery.NewRow();
                    row["BillId"] = "IGZ0000002";
                    row["ManualId"] = "Kingmond.Demo";
                    row["BillDate"] = DateTime.Today;
                    row["CustomerId"] = "Regent";
                    row["WarehouseId"] = "MyStore";
                    row["Maker"] = "kevin";
                    row["Remark"] = "Demo a report.";
                    dtDelivery.Rows.Add(row);
                }
            }

            DataTable dtDeliveryGoods = new DataTable("DeliveryGoods");
            {
                dtDeliveryGoods.Columns.Add("BillId", typeof(string));
                dtDeliveryGoods.Columns.Add("BillGoodsId", typeof(string));
                dtDeliveryGoods.Columns.Add("GoodsId", typeof(string));
                dtDeliveryGoods.Columns.Add("Quantity", typeof(int));
                {
                    DataRow row = dtDeliveryGoods.NewRow();
                    row["BillId"] = "IGZ0000002";
                    row["BillGoodsId"] = "IGZ0000002001";
                    row["GoodsId"] = "R001";
                    row["Quantity"] = 23;
                    dtDeliveryGoods.Rows.Add(row);
                }
                {
                    DataRow row = dtDeliveryGoods.NewRow();
                    row["BillId"] = "IGZ0000002";
                    row["BillGoodsId"] = "IGZ0000002002";
                    row["GoodsId"] = "R002";
                    row["Quantity"] = 36;
                    dtDeliveryGoods.Rows.Add(row);
                }
            }
            DataTable dtDeliveryDetail = new DataTable("DeliveryDetail");
            {
                dtDeliveryDetail.Columns.Add("AutoId", typeof(int));
                dtDeliveryDetail.Columns.Add("BillGoodsId", typeof(string));
                dtDeliveryDetail.Columns.Add("ColorId", typeof(string));
                dtDeliveryDetail.Columns.Add("GoodsLong", typeof(string));
                dtDeliveryDetail.Columns.Add("S1", typeof(int));
                dtDeliveryDetail.Columns.Add("S2", typeof(int));
                dtDeliveryDetail.Columns.Add("S3", typeof(int));
                {
                    DataRow row = dtDeliveryDetail.NewRow();
                    row["AutoId"] = 1;
                    row["BillGoodsId"] = "IGZ0000002001";
                    row["ColorId"] = "RED";
                    row["GoodsLong"] = "0";
                    row["S1"] = 7;
                    row["S3"] = 11;
                    dtDeliveryDetail.Rows.Add(row);
                }
                {
                    DataRow row = dtDeliveryDetail.NewRow();
                    row["AutoId"] = 2;
                    row["BillGoodsId"] = "IGZ0000002001";
                    row["ColorId"] = "WHT";
                    row["GoodsLong"] = "0";
                    row["S1"] = 2;
                    row["S2"] = 3;
                    dtDeliveryDetail.Rows.Add(row);
                }

                {
                    DataRow row = dtDeliveryDetail.NewRow();
                    row["AutoId"] = 3;
                    row["BillGoodsId"] = "IGZ0000002002";
                    row["ColorId"] = "RED";
                    row["GoodsLong"] = "0";
                    row["S1"] = 1;
                    row["S2"] = 7;
                    dtDeliveryDetail.Rows.Add(row);
                }
                {
                    DataRow row = dtDeliveryDetail.NewRow();
                    row["AutoId"] = 4;
                    row["BillGoodsId"] = "IGZ0000002002";
                    row["ColorId"] = "BLK";
                    row["GoodsLong"] = "0";
                    row["S1"] = 20;
                    row["S2"] = 8;
                    dtDeliveryDetail.Rows.Add(row);
                }
            }
            ds.Tables.Add(dtDelivery);
            ds.Tables.Add(dtDeliveryGoods);
            ds.Tables.Add(dtDeliveryDetail);
            //設(shè)置表之間的關(guān)系
            ds.Relations.Add("Delivery_DeliveryGoods", dtDelivery.Columns["BillId"], dtDeliveryGoods.Columns["BillId"]);            
            ds.Relations.Add("DeliveryGoods_DeliveryDetail", dtDeliveryGoods.Columns["BillGoodsId"], dtDeliveryDetail.Columns["BillGoodsId"]);

4、DataSet通過(guò)方法WriteXmlSchema(@"c:\temp\delivery.xml");可以很容易得到DataSet的Schema文件。

5、 設(shè)計(jì)delivery 報(bào)表格式，通過(guò)

ReportUtil.DesignReport (@"c:\temp\delivery.repx",@"c:\temp\delivery.xml")可以設(shè)計(jì)已經(jīng)存在的格式文件.
