Render the report in Angular and export it directly from code, without opening the viewer.

Exporting the document. Load and render the report, configure the requested export format, and deliver the generated bytes as a file, stream, or web response.

    selector: "exporting-many-files-to-single-pdf",

        <div class="container">
            <h4>This sample demonstrates how to export many report files to one PDF file:</h4>
            <div class="container-button">

export class ExportingManyFilesToSinglePDF {
    isLoading = false;

    async exportPdf() {
        this.isLoading = true;
        await new Promise(resolve => setTimeout(resolve, 0));

        var report = new Stimulsoft.Report.StiReport();
        report.renderedPages.clear();
        report.reportUnit = Stimulsoft.Report.StiReportUnitType.HundredthsOfInch;

        var tempReport = new Stimulsoft.Report.StiReport();
        for (var index = 0; index < 6; index++) {
            tempReport.loadDocumentFile("Reports/MasterDetailSubdetail.mdc");

            for (var page of tempReport.renderedPages.list) {
                page.report = tempReport;
                page.guid = Stimulsoft.System.Guid.newGuidString();
                report.renderedPages.add(page);
            }
        }

        var pdfData = await report.exportDocumentAsync2(Stimulsoft.Report.StiExportFormat.Pdf);
        Stimulsoft.System.StiObject.saveAs(pdfData, report.reportAlias + ".pdf", "application/pdf");
        this.isLoading = false;
    }
}

Each document's renderedPages are re-parented and added to one report; exportDocumentAsync2(StiExportFormat.Pdf) then produces a single PDF, saved to disk with StiObject.saveAs.
