Is there a way for an application to know when the report has been printed after being shown in the preview in order for the application to close the dialog box containing the XamReportPreview automatically?

The Report.PrintEnded event works when report.Print() is done but not when used with the preview:

This is fine:

        private Report PrepareReport(Visual reportSource)
        {
            // 1. Create Report object
            Report reportObj = new Report();

            // 2. Create EmbeddedVisualReportSection section.
            EmbeddedVisualReportSection section = new EmbeddedVisualReportSection(reportSource);

            // 3. Add created section to report's section collection
            reportObj.ReportSettings.Margin = new Thickness(64);
            reportObj.ReportSettings.HorizontalPaginationMode = HorizontalPaginationMode.Scale;
            reportObj.Sections.Add(section);

            return reportObj;
        }  // PrepareReport()

        private void Print_Executed(object sender, ExecutedRoutedEventArgs e)
        {
            // Print the lot list
            Report report = PrepareReport(this.xamDataGrid_Lots);
            report.PrintEnded += new EventHandler<Infragistics.Windows.Reporting.Events.PrintEndedEventArgs>(Report_PrintEnded);
            report.Print(true, true);  // show print dialog and progress dialog
        }  // Print_Executed()

        private void Report_PrintEnded(object sender, Infragistics.Windows.Reporting.Events.PrintEndedEventArgs args)
        {
            MessageBox.Show("Report Done");
        }

This doesn't work:

        private void PrintPreview_Executed(object sender, ExecutedRoutedEventArgs e)
        {
            // Print preview the lot list
            Report report = PrepareReport(this.xamDataGrid_Lots);
            PrintPreviewDialog dlg = new PrintPreviewDialog();
            dlg.Owner = this;
            dlg.SetReport(report);
            dlg.ShowDialog();
        }  // PrintPreview_Executed()
