Hi, 
I am using an upload box in an MVC application and was wondering how to send back pass or fail information back to the view.  
I am using the upload box to load an Excel file into a dataset and eventually insert that data into a sql database.  All of that is working nicely when the data is correct in the Excel and If the data is not ok, it correctly shows a red X in the upload box to the user signifying that the upload failed.
I would also like to pass on more data to the user from the Controller(count of records inserted or failed, etc...) but I can't seem to update my view.  
I have tried to pass data to the viewbag but it looks like I need to use the return Content statement or else the upload box will show the red X even if it is successful.  
How can this be done?
Thanks

Sorry for the confusion.
Basically I am trying to update my view with controller information after using the upload box.  Is a post or refresh happening or something else that is causing the viewbag not to be displayed?

I have another question besides the one above.  How do I pass something back from within the return Content  statement that doesn't result in a red X when the import has completed.

I have the following:

                result = successCount + "_" + failedCount;

                return Content(result);

If I do the above, my upload box shows a red X as if the file failed even though it uploaded correctly.

Thanks

All of this worked great...thank you.

I have another question.  Is there a way to pass data besides the file name to my controller?  For example, lets say I want to append some text to my file name in javascript in the file selected event as an identifier and I want to do something with that extra text in my controller in the same action result as my file upload...can this be done?

Hi Richard,   
  
Query: Is there a way to pass data besides the file name to my controller?  For example, lets say I want to append some text to my file name in javascript in the file selected event as an identifier and I want to do something with that extra text in my controller in the same action result as my file upload...can this be done?   
 
Response: Yes, you can pass additional data to controller through begin event of Uploadbox as shown below.   
     
@Html.EJ().Uploadbox("UploadDefault").SaveUrl("SaveDefault").RemoveUrl("RemoveDefault").ClientSideEvents(e=>e.FileSelect("onselect").Begin("uploadbegin"))   
    <script>   
        function onselect(args)   
        {   
            for (i = 0; i < args.files.length;i++)   
            {   
                args.files[i].name= args.files[i].name + "file" +i   
            }   
        }   
   
        function uploadbegin(args)   
        {   
              args.data= args.files.name    
        }   
    </script>   
 
Pass the data during begin event in script section and receive this string as additional parameter with Upload box id as shown below   
  public ActionResult SaveDefault(IEnumerable<HttpPostedFileBase> UploadDefault , string UploadDefault_data)   
         {   
             foreach (var file in UploadDefault)   
             {   
                 var fileName = Path.GetFileName(file.FileName);   
                 var destinationPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);   
                 file.SaveAs(destinationPath);   
             }   
            ViewData["data"] = UploadDefault_data;   
            return Content(UploadDefault_data);   
         }
