How to asynchronously send all the uploaded files at once in MVC Telerik Upload Control?

[M]

I am using telerik file upload control for my MVC3 application. I am using its asynchronous feature to upload the files. Below is the code that I am using.

@(Html.Telerik().Upload()
        .Name("files")
        .ShowFileList(true)    
        .Multiple(true)                                    
        .Async(
                async => async
                .Save("Save", "MyController")
                .AutoUpload(false)
                .Remove("Remove", "MyController")                            
            )
    )

[HttpPost]
        public ActionResult Save(IEnumerable<HttpPostedFileBase> files)
        {            
            foreach (var file in files)
            {
                // Some browsers send file names with full path. We only care about the file name.
                var fileName = Path.GetFileName(file.FileName);
                var destinationPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);

                file.SaveAs(destinationPath);
            }
            return Content("");
        }

The above piece of code will generate two buttons viz. "Select" and "Upload files". After selecting 4 files and pressing "upload files" button, the telerik calls the action method 4 times asynchronously (which is bad). What I wanted was the method should be called only once and all the 4 files should be send to the method at once (as I am accepting list of files).

So, How can I achieve this in Html.Telerik().Upload() control?

Also, I will be showing this control in my Html.Telerik().Window(), So I will need to send uploaded data to my parent page. Any helps how to do this too?

Thanks.

Try this


@(Html.Telerik().Upload()
.Name("files")
        .ShowFileList(true)   
        .Multiple(true)                                   
        .Async(
                async => async
                .Save("Save", "MyController")
                .AutoUpload(true)
                .Remove("Remove", "MyController")      
    )


Just set the AutoUpload true
