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）

rptQCMInspBatchCard.cs（子窗口）：
