Treeview item has a problem in Download File

[HananJ]

Hello,
Actually, I have some problem with the Treeview item in particular onClientContextMenuItemClicking as shown below:


function onClientContextMenuItemClicking(sender, args)
{

        var menuItem = args.get_menuItem();

        var node = args.get_node();

        menuItem.get_menu().hide();

 

        switch (menuItem.get_value()) {

            case "SaveAs":

                Xlate.Web.Translation.service.ResourceFilesService.ExportResourceFile('108', PassServiceHandler, FailServiceHandler);

                break;

        }

    }

Save As menu item is supposed to save resx file [RESOURCE FILE in DOTNET]; it calls a webs service to get the file from the DB, and Download the file, but the below code didn't work out in this case, but when i tried it out without Ajax or Telerick controls, I could work it out:

[WebMethod()]
        public void ExportResourceFile(string fileId)
        {
            List<ISearchResult> searchResults;
            SearchCriteria searchCriteria;
            try
            {
                    searchCriteria = new SearchCriteria();
                    searchCriteria.ResourceFileID = int.Parse(fileId);
                    searchCriteria.SearchOption = SearchType.ResxKey;

                    ResourceFile resourceFile = ResxFileManager.CreateResourceFile(searchCriteria);

                    MemoryStream memoryStream = new MemoryStream();
                    memoryStream = Manager.GenerateResxSourceCode(resourceFile);
                    memoryStream.Position = 0;
                    DownloadFile(memoryStream,resourceFile.Name);
             }
             catch (Exception ex)
             {
                 // set exception message
                string errorMessage = String.Format("Failed to export resource fileid ={0}, error:{1}", fileId ,ex.Message);

                // trace call
                TraceUtil.Write("ResourceFilesService::ExportResourceFile", "Exception occured [{0}]", errorMessage);

                // publish and rethrow the exception
                BusinessException businessExc = new BusinessException(errorMessage, ex);
                throw (businessExc);
             }
          }

        private void DownloadFile(MemoryStream memoryStream,string fileName)
        {
            byte[] byteArray = memoryStream.ToArray();
            memoryStream.Flush();
            memoryStream.Close();
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=test.resx");
            HttpContext.Current.Response.AddHeader("Content-Length", byteArray.Length.ToString());
            HttpContext.Current.Response.ContentType = "application/octet-stream";
            HttpContext.Current.Response.BinaryWrite(byteArray);

        }

DownloadFile method should force the Browser to open Save Dialog File, is there anything wrong with the code above, Could you please Help.

Hi Hanan,

I would suggest you to refer to the following help topic which elaborates on downloading files with Ajax.
I hope it helps.

Thanks for reply,
But my case that I do read the file from the Database, it has no path on the server to download it from, No href , No URL...

I tried binary.write but apparently it has some many problems with ajax panels, telerik controls, I don't now actually.!

Hi Hanan,

Could you please try to run your scenario in asp UpdatePanel instead of using RadAjax? Let me know what the result of this test is?
