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.

Hi Team, 

I would like to request the functionality to remove the Drag and Drop upload configuration using the built-in API of the Kendo UI Upload. 

Thank you!

Hello,

It appears that the Upload control is not including the header: X-Requested-With when using it in Async mode. Omitting this header is a departure from the way the other controls behave in asnyc mode. It's inconsistent and leads developers to not be able to rely on features/behaviors of the supplied the controls.

Please consider adding this header as it will bring this control functionally in-line with the behavior of other controls running in async mode.

Thanks,

Mike

Bug report

There are no configuration options dedicated to localizing the text in the arial-label attribute of these buttons. We localize other buttons, such as the "remove" and "cancel" buttons.

Reproduction of the problem

Dojo example.

1. Select a bigger file, which will allow the "pause" and "resume" buttons to appear.

Current behavior

The aria-label value is in English.

Expected/desired behavior

The aria-label value is localized.

Environment

• Kendo UI version: 2020.2.513
• jQuery version: x.y
• Browser: [all ]

Bug report

In some of the SASS themes when a file is uploaded, 'Cancel' and 'Upload' buttons are not marked as focused when navigating through Tab key

Reproduction of the problem

1. Open the Upload Overview Demo
2. Select one of the following themes - Fiori, Flat, Metro, Metro Black, Nova, Office 365
3. Upload a file
4. Navigate by using the Tab key

Current behavior

The 'Upload' and 'Cancel' buttons are not styled as focused

Expected/desired behavior

The 'Upload' and 'Cancel' buttons should be styled as focused

Environment

• Kendo UI version: 2020.2.617

With the upload contronl when I select many items at one time it create un bunch of files can be upload in same batch. But when I select many files in different selection the control create bunch for every selection. For validation purpose I need to get all files in a single upload, but I cant control how the user select his files.

Hi!

We would like to be able to copy an image from the clipboard for the kendo file upload.

An example of the feature is depicted by this service : https://pasteboard.co/

I see this as a way to setup the paste event to be captured by the component.
This feature could be used in the jQuery or angular version alike.

Thanks!

Put a KENDO Upload for JQUERY sample folder because not exits into the zip of current comercial version and internal version than KENDO Upload MVC it exist.. The idea is explain how to implement a web api across kendo upload/ saveurl /save ???

Telerik Upload is lacking image preview and scaling options. Please add support to show a thumbnail of images before uploading and also the ability to resize images on the client. This is really important when you have people wanting to upload photos and they select big files when you only need a small image. Images can be scaled server side but much faster upload and more convenient client side.

Examples of free components that already do this:
https://www.plupload.com/
https://nodeca.github.io/pica/demo/

Bug report

The complete event is triggered after each file upload if chunkSize is set.

Reproduction of the problem

1. Open this Dojo example.
2. Select at least two files to be uploaded.

Current behavior

The complete event is triggered for each file after the uploading is done.

Expected/desired behavior

The complete event should trigger only once when the upload process for all files is completed.

Workaround in this Dojo example

Environment

i really needed Upload By Folder like goolge drive uploader. i hope kendo will add that feature.

I would like to have Kendo upload widget in a popup window to track the upload progress, while user navigate through different child pages in asp.net master page application. 
Larger file upload will take time and it will be very useful to have such a capability progress through the upload while user able to perform other things.

Implement functionality that enables the dynamic change of the chunk size when uploading a file.

This change should depend on file size and upload speed. 

When uploading a file the option "allowedExtensions" cares about the case sensitivity and blocks f.e. a file called "image.PNG" when allowedExtension is set to "png" (lower cased). 

Expected: Case sensitivity will be ignored or could be activated/deactivated by another option.

If I read https://docs.telerik.com/kendo-ui/AngularJS/introduction I find “Setting Handlers through k-on Attribute” which suggests that I should be able to write `k-on-` prior to any of the events documented at https://docs.telerik.com/kendo-ui/api/javascript/ui/upload#events and automatically run under `$apply()` or `$applyAsync()`. However, when I try that, my event handler doesn’t even run at all.

I think this is an oversight.

I can reproduce this in https://dojo.telerik.com/ocESevUS which is generated from the link at https://demos.telerik.com/kendo-ui/upload/angular which uses AngularJS v1.7.2 and Kendo UI v2018.3.1017.

Hello,

I came across an issue in Kendo Upload UI for Vue. The tooltip is not getting changed on file drag. I could reproduce the same in the official kendo website.
