I am using a custom progress area after a process which processes a file and then allows the user to download the file.  I am able to display the progress area however it does not disappear once the file is ready for download.  I have tried using the client-side 'hide' function and 'cancelReqeust' function however they do not work.  Attached is the code to generating the file and updating the progressArea:

        public void ExportClicked(string mappedBinPath, string mappedImagePath) 
            ArrayList getFilesToProcess2 = new ArrayList(); 
            getFilesToProcess2 = GetFilesToProcess(); 
            if (getFilesToProcess2 == null) 
            // We want the client-side to recognize the upcoming file as a zip file. 
            _view.PageResponse.ContentType = "application/exe"
            _view.PageResponse.AddHeader("Content-Disposition", "attachment; filename=CMIS.exe"); 
            XceedSfxPrefix sfx = new XceedSfxPrefix(new DiskFile(mappedBinPath + "xcdsfx32.bin")); 
            sfx.DialogStrings[DialogStrings.Title] = "Crown Managment Information System Extraction utility"; 
            sfx.DialogMessages[DialogMessages.Introduction] = "Crown Managment Information System Extraction utility. Please click 'Continue' to proceed extracting case files to your computer."; 
            sfx.DefaultDestinationFolder = @"C:\"; 
            sfx.ExistingFileBehavior = ExistingFileBehavior.OverwriteAlways; 
            Icon ico = new Icon(mappedImagePath + "ontario.ico"); 
            sfx.Icon = ico
            // We will zip directly in the response stream. The temporary compressed 
            // data will be written to the ZipArchive's TempFolder, thus the MemoryFolder  
            // we set in Application_Start. 
            ZipArchive destination = new ZipArchive(new StreamFile(_view.PageResponse.OutputStream)); 
            ArrayList refineProcessList = RefineProcessList(getFilesToProcess2); 
            _view.Progress["SecondaryTotal"] = refineProcessList.Count.ToString(); 
            foreach (int file in refineProcessList) 
                _view.Progress["CurrentOperationText"] = file.ToString(); 
                AddFolderAndFiles(dmConnection.DmDocumentSecurityToken, dmConnection.DmLibraryName, file, destination, "", new ArrayList()); 
                _view.Progress["SecondaryValue"] = refineProcessList.IndexOf(file).ToString(); 
                string test2 = _view.StringClientScript; 
            _view.Progress["CurrentOperationText"] = "Completed"; 
            string test1 = _view.StringClientScript; //calls javascript hide() function 
            destination.SfxPrefix = sfx
            destination.DefaultCompressionMethod = Xceed.Compression.CompressionMethod.Deflated; 
            // And finally we zip in a single operation. If we had to zip more than 
            // one source, we could have used ZipArchive.BeginUpdate/EndUpdate. 
            ArrayList nameFilters = new ArrayList();

Hi David,

The progress area does not disappear, because the page does not get reloaded, which in turn happens, because of the Response.End call in the end of the method.

If your scenario need to have the Response.End call, you can handle the OnClientProgressUpdating event, where you can determine if the progress data is the last expected and use the hide() method to hide the progress area.

Let me know if I am missing something.
