There seem to be only 3 MVVM bindings supported for the upload tool right now:  enabled, visible, and events.  If you are using Kendo templates to host this tool, this is kind of a deal breaker if you need to bind any data to the upload tool, e.g. files.  Please add files at a minimum.

because .k-file.k-file-success <li> removal is deffered and so is still present on success event.

The current upload control does not allow the PUT verb. This means you cannot use it with Amazon S3 without implementing a proxy server. The problem with the proxy server approach is that it places unneeded strain on your own servers and you get charged twice for data transfer, once on the way in to the proxy server and again from the proxy server to S3.

It would be nice to have xhr in upload's remove event handler since sometimes we need to modify/add http headers on request.

It woudl be great if we coudl access an images dimensions on upload, to avoid having to do server trips to determine if an image is valid.

Hi. I'd love to use the file upload widget, but, like most devs, I need to do more than just upload a file.....html does that just fine. I need to be able to save the file name and size, possibly the extension, in a mysql database using php.

Please consider these enhancements to the file upload widget for the next release. I know you all are working on PHP wrappers and I hope a lot more documentation and tutorials for us PHP developers, so an upgrade like this, or a tutorial on the site that provides a working example of saving file details to the database using PHP could be added easily.

Thanks and keep the PHP stuff coming! It's making a huge difference and I think, based on the number of votes here, there are a ton of folks interested in using Kendo UI with PHP.

Upload for MVC lucks upload in chunks feature as upload for ajax. So it is impossible to upload large files (like more than technical limit for asp.net in 4Gb). In my current project with 360 degrees videos where files might be 10+ Gb it is vital.

when we want to storage files directly to Azure storage we need first to upload the files to the server and then upload from the server to the azure storage...
why there isn't an option like RadCloudUpload that support cloud storage providers ?

In order to be able to manage files attached to server objects, it would be nice if we could bind the Upload widget to a datasource. 
The read() method of the datasource could be used to load the widget with the list of files attached to a given server object. 
The create() method would be used to upload new files to the sever.
The destroy() method would be used for deleting existing files on the server.

This would make the upload widget more consistent with other widgets like the combo boxes or the dropdown lists.

The upload control takes up a lot of space on the web page when you upload a lot of files.  As each file completes, I want an easy way to remove those files.  Ideally, a configuration option to automatically remove completed files otherwise a function to remove the file from the list from within the Success event.

Provide the image preview option for kendo upload.

Add support to the Upload widget to upload files to an OData service, for instance to add attachments to SharePoint list items using SharePoints OData service. 

At the same time it would be good to be able to specify the urls for the Upload widget in an upload-datasource in a view model to which the Upload widget is databound, basically separate the uploading from the widget. That way you can choose to use an OData upload-datasource or a multipart/form-data upload-datasource. Obviously this OData upload-datasource may only be supported in browsers that support the HTML5 file api.

KendoUI Upload Widget: 
- It would be great if it would be possible to defined a maxfileSize for specific file types and not only 1 maxFileSize for all file types. F.e.:
.jpg -> 500KB
.png -> 700KB
...

- In the SELECT event it should be possible to remove files from the file list (f.e. after doing programmatic validation to find files that should not uploaded: files.remove(id); So they are not displayed in progess/status window and will not be uploaded at all.

I would like to be able to use a progress bar while uploadiing files synchronous using the MVC Upload control

I would like to be able to be able to use unique filenames when uploading files asynchronous or maybe filnames based on GUID names

Would you consider adding a property for "FileSource" to the Files option of the upload widget?  Then i could set the base 64 string (since the images are stored in the database).  This would make it so much easier to display an image preview for these files.  Right now I have to do a hack because this is not supported (see ticketID: 1348670).  Please consider adding this property for the next version - thank you!

Here is what the code would look like with the new property available: 

                    .Files(files =>
                    {
                        foreach (var file in Model.Attachments)
                        {
                            files.Add().Name(file.FileName).Extension(file.Extension).Size(file.Size).FileSource(file.Base64Src);
                        }
                    }

I see in the forums you do not support what i need - but we really need it and will have to use a different control without it.  We need the ability to have the upload control, look, feel and act like it does in "Async Mode".  But when in this mode we need it to only upload 1 or two individual files at a time.  The issue is not bandwidth it is processing power.  So the "batch" trick doesn't work - we don't need all the files at once.  We need one file at-a-time, with the easy of letting the user pick a bunch and see them all listed out.  Something like

Async{  throttleLimit: 2}  - Where throttle limit simply keeps the number of pending uploads to 2 and waits until they succceed/fail to start uploading the next and so on.

Hi Team, I suggest the feature which can be copy and paste image while upload images. 
For fashion industry, we handle many images of clothes and we need to upload image to legacy system. 
However, we don't upload images by drag drop of them. We add the arrows, shapes and some texts about the image on the Excel
As of now, we capture all of them and put the image editing tool and then save and upload. so, if there's new feature which can be paste from clipboard, it'll be save much time for many person. 

Example of free component that already do this:

It would be very helpful if you could standardize the button configuration across all widgets to have the same styling and usage properties. Specifically, the KendoUploader button does not have the configuration options for spriteCssClass, icon, or imageUrl. It is possible to add a background icon via css, but in some cases a texture or other background icon may be used across the entire button, making it very difficult to apply a icon as a background to the button also.

There should be a render function of some sort that can be called that changes how the Uploads are displayed.
In the attached image, I uploaded a single file, then two additional files.
Rather than having a set of one and a set of two, I'd prefer to have either a set of three, or three sets of 1. 

I understand that the plugin creates an input element for each individual uploading, however, I think there would be value in being able to join or split those files into multiple elements. It may even be beneficial to add and utilize a FileList object in the Kendo Upload object, as this would allow for the uploads to be sorted alphabetically, or by type, and so on. 

To recreate the behavior mentioned, simply upload any number of files to an Upload control and then do that one more time. The behavior can be recreated on the Telerik website demos.
