按钮弹出（获取当前页面选中的BatchID，通过构造函数传参传入子窗口并打开窗口）：

frmQCMTranInspBatchList.cs（父窗口）

  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）
