首先新建一个XtraReport类。根据需要设计报表页面布局;子报表需要添加DetailReport
布局设计完毕后,写代码绑定数据;
using System; using System.Drawing; using System.Collections; using System.ComponentModel; using DevExpress.XtraReports.UI; using System.Data; using Zeda.AssistantClass; namespace LYWJMIS { public partial class MainAndChild : DevExpress.XtraReports.UI.XtraReport { private DataSet dsSheet; private DataSet dsDetail; public MainAndChild() { InitializeComponent(); this.AfterPrint += new EventHandler(MainAndChild_AfterPrint); } void MainAndChild_AfterPrint(object sender, EventArgs e) { //this.InsertPageBreaks(this.xrPageBreak1); } public MainAndChild(DataSet dsSheet, DataSet dsDetail) : this() { this.dsDetail = dsDetail; this.dsSheet = dsSheet; DataSet dsRep =new DataSet(); DataTable dtSheet = dsSheet.Tables[0].Copy(); dtSheet.TableName="parent"; dsRep.Tables.Add(dtSheet); DataTable dtDetail = dsDetail.Tables[0].Copy(); dtDetail.TableName = "child"; dsRep.Tables.Add(dtDetail); GroupField gf = new GroupField("ID", XRColumnSortOrder.Ascending); GroupHeader1.GroupFields.Add(gf); //设置主表和从表的父子关系 DataColumn parentColumn = dsRep.Tables["parent"].Columns["ID"]; DataColumn childColumn = dsRep.Tables["child"].Columns["DB0025A"]; DataRelation R1 = new DataRelation("R1", parentColumn, childColumn); dsRep.Relations.Add(R1); //绑定主表的数据源 this.DataMember = "parent"; this.DataSource = dsRep; //绑定明细表的数据源 this.DetailReport.DataMember = "R1"; this.DetailReport.DataSource = dsRep; //this.DetailReport.dat BindTableData(dsRep); BindFormData(dsRep); //在页脚之后设置分页符 GroupFooter1.PageBreak = PageBreak.AfterBand; } /// <summary> /// 绑定采购单明细信息 /// </summary> private void BindTableData(DataSet ds) { //为XRTable的每一列绑定数据集及对应的字段 this.xrTableCell1.DataBindings.Add("Text", ds, "R1.DB0137A");//名称 (DB0137A为字段名称) this.xrTableCell2.DataBindings.Add("Text", ds, "R1.DB0152A");//规格 this.xrTableCell3.DataBindings.Add("Text", ds, "R1.DB0150A");//单位 this.xrTableCell7.DataBindings.Add("Text", ds, "R1.DB0151A");//产地 this.xrTableCell8.DataBindings.Add("Text", ds, "R1.DB0168A");//剂型 this.xrTableCell9.DataBindings.Add("Text", ds, "R1.DB0183A");//计量规格 this.xrTableCell10.DataBindings.Add("Text", ds, "R1.DB0188A", "{0:n2}");//进价 this.xrTableCell11.DataBindings.Add("Text", ds, "R1.DB0354A", "{0:f0}");//数量 //设置本页小计(数量小计),SummaryRunning.Page指定统计范围,只统计本页数量。 this.xrTableCell23.DataBindings.Add("Text", ds, "R1.DB0354A", "{0:f0}");//数量 this.xrTableCell23.Summary = new XRSummary(SummaryRunning.Page, SummaryFunc.Sum, string.Empty); //绑定本单合计,SummaryRunning.Group 指定统计范围,统计每一组(一个采购单为一组)数量。 this.xrLabel7.DataBindings.Add("Text", ds, "R1.DB0354A","{0:f0}"); this.xrLabel7.Summary = new XRSummary(SummaryRunning.Group,SummaryFunc.Sum,string.Empty); } /// <summary> /// 绑定采购单明细信息 /// </summary> private void BindFormData(DataSet ds) { //XRLabel绑定数据 方法1: this.txtDB0336A.DataBindings.Add("Text",ds,"DB0336A"); //XRLabel绑定数据 方法2: this.txtDB0337A.DataBindings.Add(new XRBinding("Text", ds, "DB0337A", "{0:yyyy-MM-dd}")); this.txtDB0005A.DataBindings.Add("Text", ds, "DB0005A"); this.txtDB0339A.DataBindings.Add("Text", ds, "DB0339A"); this.txtDB0345A.DataBindings.Add(new XRBinding("Text", ds, "DB0345A", "{0:n2}")); this.labPrintTime.Text = DateTime.Now.Date.ToString(); } } }

private void customButton1_Click(object sender, EventArgs e) { DataSet dsDetail=DataService .Instance .GetPurchaseSheetDetailInfoByDate(this.dtpDate .DStartDate,this.dtpDate .DEndDate); MainAndChild rep = new MainAndChild(dsSearch,dsDetail); //设置纸张类型为自定义 rep.PaperKind = System.Drawing.Printing.PaperKind.Custom; //设置纸张大小 double width = 24.1 * 0.3937008 * Dpi.GetDeviceCapsX(); double height = 9.3 * 0.3937008 * Dpi.GetDeviceCapsY(); rep.PageSize = new System.Drawing.Size((int)width, (int)height); //打印预览 rep.ShowPreview(); }
