Password protection with ActionResult

I would like to protect xls document with a password to prevent modification.

This is the code:

                workbook.SetWriteProtectionPassword(db.Settings.FirstOrDefault(c => c.SettingCode.Equals("XLS_PASSWORD_PROTECTION")).SettingVal);
                // Set the workbook as read-only.
                workbook.ReadOnlyRecommended = true;

     workbook.Version = ExcelVersion.Excel2013;
                        return excelEngine.SaveAsActionResult(workbook, work.WorkCode + ".xlsx", HttpContext.ApplicationInstance.Response, ExcelDownloadType.PromptDialog, ExcelHttpContentType.Excel2013);

The xls document is generated correctly, but when I open it (it is downloaded from browser) I can modify it without password protection.

How can I solve the problem?

Thanks. Claudio
