The button pops up (get the BatchID selected on the current page, pass parameters into the child window through the constructor and open the window):

FrmQCMTranInspBatchList.cs (parent window)

Private void btnInspBatchPrint_ItemClick (object sender, DevExpress.XtraBars.ItemClickEventArgs e) {try {GlobalVariable.gaSelectPOID.Clear (); int [] iaPOs = gdvDetail.GetSelectedRows (); if (iaPOs.Length)

< 1) { CommonFunction.ShowMsgBox("请选择一条或多条参数");//ToDo: Multi-Language return; } int[] iaRAWID = new int[iaPOs.Length];//+2 string sBatchID = ""; for (int i = 0; i < iaPOs.Length; i++) { sBatchID = gdvDetail.GetRowCellValue(iaPOs[i], "BATCH_ID").ToString(); } //saPARA_ID[iaPOs.Length] = cboModelVer.EditValue.ToString(); //saPARA_ID[iaPOs.Length + 1] = "EVENT"; rptQCMInspBatchCard InspBatchCard = new rptQCMInspBatchCard(sBatchID); DevExpress.XtraReports.UI.ReportPrintTool printTool = new DevExpress.XtraReports.UI.ReportPrintTool(InspBatchCard); printTool.ShowPreviewDialog(); } catch (Exception ex) { CommonFunction.ShowMsgBox("frmAPSReleaseWO.btnSelect_Click()\n" + ex.Message); } } 子窗口获取参数，并根据该参数执行SQL语句查询需要的数据，再将查到的数据放入Report中（条形码赋值即可自动生成） rptQCMInspBatchCard.cs（子窗口）： using System;using System.Drawing;using System.Collections;using System.ComponentModel;using DevExpress.XtraReports.UI;using System.Data;using TRSCore;using System.Text;using MESCore;namespace QCMCore.Reports{ public partial class rptQCMInspBatchCard : DevExpress.XtraReports.UI.XtraReport { public rptQCMInspBatchCard(string sBatchId) { InitializeComponent(); this.sBatchID = sBatchId; } #region Variable private string sBatchID; #endregion #region Function private bool FillHeader() { try { DataTable dtOrd = new DataTable(); dtOrd.Columns.Add("BATCH_ID"); dtOrd.Columns.Add("LOT_ID"); dtOrd.Columns.Add("START_RES_ID"); dtOrd.Columns.Add("MAT_ID"); TRSNode in_node = new TRSNode("Sql_In"); TRSNode out_node = new TRSNode("Sql_Out"); StringBuilder sb = new StringBuilder(); CommonRoutine.SetInMsg(in_node); string sFactory =in_node.Factory; in_node.ProcStep = '1'; in_node.AddInt("NEXT_ROW", 0); sb.Append("SELECT A.BATCH_ID, A.LOT_ID, A.START_RES_ID, A.MAT_ID FROM WIPLOTSTS A INNER JOIN QCMITEMINSP B ON A.LOT_ID = B.ITEM_ID WHERE A.FACTORY =B.FACTORY "); sb.Append(" AND B.FACTORY= '"+sFactory+"' AND B.BATCH_ID='" + sBatchID+"' "); in_node.SetString("SQL", sb.ToString()); do { if (CommonRoutine.CallService("BAS", "BAS_SQL_Query", in_node, ref out_node) == false) { return false; } CommonRoutine.ConvertToDataTable(dtOrd, out_node); in_node.SetInt("NEXT_ROW", out_node.GetInt("NEXT_ROW")); } while (in_node.GetInt("NEXT_ROW") >
