如何根据打印介质类型设置报告参数？

Question

我需要根据生成报告的打印介质在SSRS报告中切换一些演示文稿。

我必须对一堆报告（SalesInvoice，SalesConfirm，SalesQuotation）进行此操作。

问题是我找不到可以同时访问这两项的访问点：

• 在SalesInvoiceJournalPost类中，我可以访问打印介质，但不能访问SalesInvoiceContract
• 在SalesInvoiceController类中，我可以访问SalesInvoiceContract，但是printsettings给我错误的值

在SalesInvoiceJournalPost.init中，我尝试：

printSettings = SysOperationHelper::base64Decode(chainFormletterContract.parmPrintersettingsFormletter());
printDestinationSettings = new SRSPrintDestinationSettings(printSettings);

if (printDestinationSettings.printMediumType() == SRSPrintMediumType::Email)
{
    // Can't access Report Parameter from here
}

在SalesInvoiceController.main中，我尝试：

printDestination = formLetterController.parmReportContract().parmPrintSettings();
salesInvoiceContract = formLetterController.parmReportContract().parmRdpContract() as SalesInvoiceContract;
salesInvoiceContract.paramMyValue(
    // this is always false because printMedium is always Screen
    printDestination.printMediumType() == SRSPrintMediumType::Email
);

事实证明，只有几步分离，您才能从控制器获得SRSPrintDestinationSettings。这是SalesInvoiceController.outputReport：

PrintMgmtPrintSettingDetail printSettingDetail;
SRSPrintDestinationSettings printDestinationSettings;

printSettingDetail = formLetterReport.getCurrentPrintSetting();
printDestinationSettings = printSettingDetail.parmPrintJobSettings();
salesInvoiceContract.paramMyValue(
    printDestinationSettings.printMediumType() == SRSPrintMediumType::Email
);
