In my ultragrids I have options for exporting to excel using the UltragridExcelExporter.   When I export I do not want the formulas to be exported, just the cell data.  How can I do this? 

Currently this is the code I am using to export my grids:

                var filePath = Application.StartupPath + "\\Export-" + Guid.NewGuid().ToString() + ".xls";
                var wkBook = new Workbook();
                wkBook.Worksheets.Add("Margins");
                excelExporter.Export(grdMain, wkBook, 0, 0);
                excelExporter.Export(grdSupp, wkBook, 75, 1);
                wkBook.Save(filePath);
                System.Diagnostics.Process.Start(filePath);

Thanks!
