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.

Bug report

The getFiles method does not return correct results when used in the success event. If you upload a file, the method in the success event will return an array with one item. If you remove a file, the same would return again an array with one item.

Reproduction of the problem

  1. Open this Dojo example.
  2. Upload a file and open the console.
  3. Remove the file.

Current behavior

GetFiles returns an array with one item after removing the file from the list.

Expected/desired behavior

The method should return an empty array.

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

Reproduction of the Problem:

Dojo: http://dojo.telerik.com/@grabbi/ayiQOGoT

  • Select multiple files in Upload-Widget with not allowed extensions or filesize greater then allowed
  • Remove one File from the list (not the last one)
  • Then the upload of the next file starts

This behaivior only occures when Chunk Upload is selected and some kind of validation is activated too.

Expected behaivior:

When Removing a file the file is just removed from the list and no upload ist starting.



<input name="file" id="file" type="file" />


    $(document).ready(function () {

            async: {
                withCredentials: false,
                saveUrl: "save",
                chunkSize: 2000000,
                saveField: "files",
                autoUpload: false
            validation: {
                maxFileSize: 500

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.
