pull模式 代码如下
private void ShowCrystalReport() { string strDBServer = Application["DBServer"].ToString(); string strDBName = Application["DBName"].ToString(); string strUserId = Application["DBUserID"].ToString(); string strPassword = Application["DBPassword"].ToString(); //连接代码 CrystalReportSource1.ReportDocument.Load(Server.MapPath("Report/JPInvoice.rpt")); CrystalReportSource1.ReportDocument.SetDatabaseLogon(strUserId, strPassword, strDBServer, strDBName); //设置参数 CrystalReportSource1.ReportDocument.SetParameterValue("Invoice_No_From", strInvoiceForm); CrystalReportSource1.ReportDocument.SetParameterValue("Invoice_No_To", strInvoiceTo); CrystalReportSource1.ReportDocument.SetParameterValue("TRX_Date_From", strDateFrom); CrystalReportSource1.ReportDocument.SetParameterValue("TRX_Date_To",strDateTo ); CrystalReportSource1.ReportDocument.SetParameterValue("Org_ID", "86"); CrystalReportSource1.ReportDocument.SetParameterValue("SOB_ID", "2029"); CrystalReportSource1.DataBind(); CrystalReportViewer1.ReportSource = CrystalReportSource1; CrystalReportViewer1.DataBind(); }
开始遇到的问题是 “无法加载数据库 crdb_oracle.dll”
解决方法:
1) 找到 crdb_oracle.dll.
«C:Program FilesCommon FilesBusiness Objects3.0in»或者在
«C:Program FilesCommon FilesCrystal Decisions2.0in»中(Crystal 9)
2)Copy to «C:Program FilesCommon FilesBusiness Objects2.7Bin
3)Reload solution.
后来又遇到问题 您请求的报表需要更多信息 如图:
首先检查DBServer和用户名密码是否配置正确,重新编译一次。
另外 修改了代码
private void ShowCrystalReport() { TableLogOnInfo log = new TableLogOnInfo(); ReportDocument rd = new ReportDocument(); log.ConnectionInfo.ServerName = Application["DBServer"].ToString(); log.ConnectionInfo.Password = Application["DBPassword"].ToString(); log.ConnectionInfo.UserID = Application["DBUserID"].ToString(); log.ConnectionInfo.DatabaseName = Application["DBName"].ToString(); rd.Load(Server.MapPath("Report/JPInvoice.rpt")); rd.SetParameterValue("Invoice_No_From", strInvoiceForm); rd.SetParameterValue("Invoice_No_To", strInvoiceTo); rd.SetParameterValue("TRX_Date_From", strDateFrom); rd.SetParameterValue("TRX_Date_To", strDateTo); rd.SetParameterValue("Org_ID", "86"); rd.SetParameterValue("SOB_ID", "2029"); rd.Database.Tables[0].ApplyLogOnInfo(log);//获得第一个table CrystalReportViewer1.ReportSource = rd; CrystalReportViewer1.DataBind(); }
