            fReport.PrintingSystem.ExecCommand(PrintingSystemCommand.StopPageBuilding);
            fReport.SaveLayout(saveFileName);
            using(XtraReport newReport = XtraReport.FromFile(saveFileName, true)) {
            XRDesignFormExBase designForm = new CustomDesignForm();
                designForm.OpenReport(newReport);
            designForm.FileName = fileName;
            ShowDesignerForm(designForm, this.FindForm());
            if(designForm.FileName != fileName && File.Exists(designForm.FileName))
                File.Copy(designForm.FileName, fileName, true);

            designForm.OpenReport((XtraReport)null);
