When printing and exporting go through the viewer, you can intercept them in the page model to adjust the document or its export settings.

Registering the actions. Name PrintReport and ExportReport in the viewer options:
@Html.StiNetCoreViewer(new StiNetCoreViewerOptions()
{
    Actions =
    {
        GetReport = "GetReport",
        PrintReport = "PrintReport",
        ExportReport = "ExportReport",
        ViewerEvent = "ViewerEvent"
    }
})

Customizing export. In the export handler you can read the format and tune the settings before returning the result:
public IActionResult OnPostExportReport()
{
    var report = StiNetCoreViewer.GetReportObject(this);
    var parameters = StiNetCoreViewer.GetRequestParams(this);
    report.ReportName = "MyReportName";

    if (parameters.ExportFormat == StiExportFormat.Pdf)
    {
        var settings = (StiPdfExportSettings)StiNetCoreViewer.GetExportSettings(this);
        settings.CreatorString = "My Company";
        return StiNetCoreViewer.ExportReportResult(this, report, settings);
    }
    return StiNetCoreViewer.ExportReportResult(this, report);
}

This hook lets you rename the output, apply format-specific settings, enforce security or log activity while the user still exports from the viewer toolbar.
