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.

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:

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.

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.

Please find the screenshot below

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

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.

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


  • Kendo UI version: 2020.1.114
  • Browser: [all]
