[转载]ActiveReport在.net中的简单应用，子报表制作 – 挂在墙上的天堂 – 博客园.
先上图，最终效果如下：
可以连续打印。
具体功能就是大报表里面再套一个子报表。
考察了几个报表控件，在b/s下面ActiveReport还是比较好用的，简单，实用
具体步骤如下：
1、安装ActiveReports for .NET 3.0 Setup.exe，到官网自己下。
2、用自己的金钱、魅力、或者智慧注册之~~~~~不注册也可以用，不过报表上会有红色字体提示。
3、在项目中新建报表文件
4、在新建的报表文件上右键选择“视图设计器”，直接双击的话就会用vs代码编辑器打开，这里b/s和c/s是不一样的。c/s里面双击就是视图设 计器了。
5、和设计网页一样，在页面上布置各种控件
画完的页面如下：
在左上角的地方有个按钮，
，这里面可以更改报表的信息，如纸张大小、纸张方向等，我选的就是A4纸、横向
这里不多说了，注意设定好页面里面每个地方的绑定字段，另外在右侧有一个子报表SubReport，在这里
这个放后面说~~~
点上面的数据库图标可以直接连接数据库进行测试，这个自己试验就ok，实际应用时都是用代码控制，这里控制太不灵活。另外需要说明的一点是，可以在 这里把测试数据提取出来，方便选择每个地方的字段~~~不多说了，看图
6、下面开始做现实报表的网页
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ZhunKaoZheng.aspx.cs" Inherits="ExamSys.Report.ZhunKaoZheng" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title></title> <meta name="GENERATOR" content="Microsoft Visual Studio 7.0"> <meta name="CODE_LANGUAGE" content="C#"> <meta name="vs_defaultClientScript" content="VBScript"> <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5"> <link rel="stylesheet" type="text/css" href="default.css"> </head> <body> <form id="ActiveXExport" method="post" runat="server"> </form> <div id="pagebody"> <object id="arv" codebase="arview2.cab#version=-1,-1,-1,-1" height="800" width="100%" classid="clsid:8569D715-FF88-44BA-8D1D-AD3E59543DDE" viewastext> <param name="_ExtentX" value="26141"> <param name="_ExtentY" value="11959"> </object> <script language="vbscript"> <!-- sub arv_ControlLoaded() arv.DataPath = "ZhunKaoZheng.aspx?ReturnReport=1" end sub --> </script> </div> </body> </html> |
需要注意的是我这个控件是引用在form外面的，在里面不好使哦!!!
还有这个
arv.DataPath = "ZhunKaoZheng.aspx?ReturnReport=1" 是必须加的，记得ZhunKaoZheng.aspx就是本页面的地址，具体为什么加我也不知道，谁知道为啥记得告诉我哦。
后台代码如下：
using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Drawing; using System.Web; using System.Web.SessionState; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.HtmlControls; using System.IO; using DataDynamics.ActiveReports; using ExamSys.DBUtility; using System.Data.SqlClient; using System.Data; namespace ExamSys.Report { public partial class ZhunKaoZheng : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string strSql=""; if (Session["personid"].ToString() != "" && Session["personid"] != null) { strSql = @"SELECT T_PERSON.ID, T_PERSON.NAME, T_PERSON.PHOTO, T_PERSON.BH_SHENFENZHENG, T_PERSON.BAOMING_NO, T_PERSON.DEP, ExamUser.examID, T_PERSON.DEP_BIANHAO, T_INFO.NAME AS DEP_NAME, ExamList.elClass FROM ExamList INNER JOIN ExamUser ON ExamList.elID = ExamUser.elID INNER JOIN T_PERSON ON ExamUser.personID = T_PERSON.ID INNER JOIN T_INFO ON T_PERSON.DEP_BIANHAO = T_INFO.ID WHERE (T_PERSON.ID = '" + Session["personid"].ToString() + @"')"; } else { strSql = @"SELECT T_PERSON.ID, T_PERSON.NAME, T_PERSON.PHOTO, T_PERSON.BH_SHENFENZHENG, T_PERSON.BAOMING_NO, T_PERSON.DEP, ExamUser.examID, T_PERSON.DEP_BIANHAO, T_INFO.NAME AS DEP_NAME, ExamList.elClass FROM ExamList INNER JOIN ExamUser ON ExamList.elID = ExamUser.elID INNER JOIN T_PERSON ON ExamUser.personID = T_PERSON.ID INNER JOIN T_INFO ON T_PERSON.DEP_BIANHAO = T_INFO.ID WHERE (T_PERSON.DEP_BIANHAO = '" + Session["dep"].ToString() + @"') AND (ExamUser.elID IN (SELECT ELID FROM EXAMLIST AS EXAMLIST_1 WHERE (ELCLASS = '" + Session["bigtitle"].ToString() + "')))"; } strSql = strSql.Replace("\r", " ").Replace("\n", " "); DataSet myDS = SQLHelper.GetDataSet(strSql); DataTable myDT = GetDistinctTable(myDS.Tables[0], "id"); string sReturnReport = this.Page.Request.QueryString["ReturnReport"]; if ((sReturnReport != null) && (sReturnReport.Trim().Length != 0)) { this.Page.Response.Buffer = true; ActiveReport3 rpt = null; try { //这两句话是重点 rpt = new rptZhunKaoZheng(); rpt.DataSource = myDT; rpt.DataMember = myDT.TableName; rpt.Run(false); } catch (DataDynamics.ActiveReports.ReportException eRunReport) { this.Trace.Warn("Report failed to run:\n" + eRunReport.ToString()); } MemoryStream outStream = new MemoryStream(); rpt.Document.Save(outStream, DataDynamics.ActiveReports.Document.RdfFormat.AR20); outStream.Seek(0, SeekOrigin.Begin); byte[] bytes = new byte[outStream.Length]; outStream.Read(bytes, 0, (int)outStream.Length); this.Page.Response.ClearContent(); this.Page.Response.ClearHeaders(); this.Page.Response.BinaryWrite(bytes); this.Page.Response.End(); } } /// <summary> /// 获取对固定列不重复的新DataTable /// </summary> /// <param name="dt">含有重复数据的DataTable</param> /// <param name="colName">需要验证重复的列名</param> /// <returns>新的DataTable，colName列不重复，表格式保持不变</returns> private DataTable GetDistinctTable(DataTable dt, string colName) { DataView dv = dt.DefaultView; DataTable dtCardNo = dv.ToTable(true, colName); DataTable Pointdt = new DataTable(); Pointdt = dv.ToTable(); Pointdt.Clear(); for (int i = 0; i < dtCardNo.Rows.Count; i++ ) { string ss=dtCardNo.Rows[i][0].ToString(); DataRow dr = dt.Select(colName +"="+ ss)[0]; Pointdt.Rows.Add(dr.ItemArray); } return Pointdt; } } } |
为了确保能看的清楚，无关的代码我也不删除了。里面最重要的是
rpt = new rptZhunKaoZheng();
rpt.DataSource = myDT;
rpt.DataMember = myDT.TableName;
rpt.Run(false);
7、这样主报表就现实成功了，下面开始子报表的制作~~
8、同样的方法建立子报表模板
注意里面的标题栏为groupHeader，子报表的标题一定要选这个，不然不能在主报表里面现实，可以右键选择添加、删除标题栏
在里面设定好需要显示的字段就O了
9、更改主报表
1）选择主报表的detail模块，添加Format事件，这里面主要设置子报表的DataSource和DataMember
private void detail_Format(object sender, EventArgs e) { //string strSql1 = "SELECT EXAMLIST.ELNAME, SiteInfo.siName, T_PSSBSchema.seatnum, ExamOrder.eoBegin, ExamOrder.eoEnd FROM T_PSSBSchema INNER JOIN SiteInfo ON T_PSSBSchema.siID = SiteInfo.siID INNER JOIN ExamOrder ON SiteInfo.siID = ExamOrder.siID INNER JOIN EXAMLIST ON T_PSSBSchema.elID = EXAMLIST.ELID AND ExamOrder.elID = EXAMLIST.ELID WHERE (T_PSSBSchema.examID = '" + this.label9.Text + "')"; string strSql = @"SELECT ExamList.elName, SiteInfo.siName, ExamUser.seatnum, ExamOrder.eoBegin, ExamOrder.eoEnd FROM ExamUser INNER JOIN SiteInfo ON ExamUser.siID = SiteInfo.siID INNER JOIN ExamOrder ON SiteInfo.siID = ExamOrder.siID INNER JOIN ExamList ON ExamUser.elID = ExamList.elID AND ExamOrder.elID = ExamList.elID WHERE (ExamUser.examID = '" + this.label9.Text + "')"; strSql = strSql.Replace("\r", " ").Replace("\n", " "); DataTable myDT = SQLHelper.GetDataSet(strSql).Tables[0]; Time2CharConvert(myDT, "eoBegin", "f"); Time2CharConvert(myDT, "eoEnd", "t"); this.srptKaoChang.Report.DataSource = myDT; this.srptKaoChang.Report.DataMember = myDT.TableName; //((DataDynamics.ActiveReports.DataSources.SqlDBDataSource)this.srptKaoChang.Report.DataSource).ConnectionString = "data source=127.0.0.1;initial catalog=kuaiji;password=sa;persist security info=True;user id=sa"; //((DataDynamics.ActiveReports.DataSources.SqlDBDataSource) this.srptKaoChang.Report.DataSource).SQL = "SELECT EXAMLIST.ELNAME, SiteInfo.siName, T_PSSBSchema.seatnum, ExamOrder.eoBegin, ExamOrder.eoEnd FROM T_PSSBSchema INNER JOIN SiteInfo ON T_PSSBSchema.siID = SiteInfo.siID INNER JOIN ExamOrder ON SiteInfo.siID = ExamOrder.siID INNER JOIN EXAMLIST ON T_PSSBSchema.elID = EXAMLIST.ELID AND ExamOrder.elID = EXAMLIST.ELID WHERE (T_PSSBSchema.examID = '" + this.label9.Text + "')"; } |
10、选择报表主体，添加ReportStart和ReportEnd事件。
rptKaoChang _rptKaoChang = null; private void rptZhunKaoZheng_ReportStart(object sender, EventArgs e) { //Check to see if the holder subreport object is assigned, if not create it //Creating the subreport here will only create one instance to use if (_rptKaoChang == null) { _rptKaoChang = new rptKaoChang(); this.srptKaoChang.Report = _rptKaoChang; this.srptKaoChang.Report.DataSource = new DataDynamics.ActiveReports.DataSources.SqlDBDataSource(); } } private void rptZhunKaoZheng_ReportEnd(object sender, EventArgs e) { //clean up existing subreport document object _rptKaoChang.Document.Dispose(); //clean up existing subreport object _rptKaoChang.Dispose(); //Reset subreport to null, so if this report is called again it will reinit inside the section format event _rptKaoChang = null; } |
在此进行子报表的初始化和关闭。
11、结束战斗，测试OK~~~
