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.

Environment

• Kendo UI version: 2020.1.406

• 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.

Code:

 

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

<script>

    $(document).ready(function () {

        $("#file").kendoUpload({
            async: {
                withCredentials: false,
                saveUrl: "save",
                chunkSize: 2000000,
                saveField: "files",
                autoUpload: false
            },
            validation: {
                maxFileSize: 500

If we have a upload control with simple validation on allowed extensions and upload 50 files, the "k-upload-status" element prematurely gets set to "Done" once it finds a file type that is not allowed.  If a user is not paying attention they could think that the upload is complete.  It seems silly to mark an entire queue of files as "Done" after the first failure while uploading multiple items and while items are still uploading.  While the upload may technically be "done" it really failed and should say "Partially done" or some other message than "Done".

Also, placing an exclamation icon next to done is not very clear when an file does legitimately fail.  The icon needs to be more prevalent and have a tooltip to describe it further.  Most of my users in production have not noticed the icon and have thought that the upload completed.  This is especially a problem if a user is uploading thousands of files and does not scroll down during/after upload.

Filter just certain types of files by extension (.csv, .doc, .jpg, etc.).

When we upload files with the Kendo Upload, it would be nice to upload them sequentially, in separate requests

Hello

 

on https://demos.telerik.com/kendo-ui/upload/async

 

In the area also available for

Also available for:

 

• ASP.NET MVC
 
• ASP.NET Core

 

the .net core link is broken

https://demos.telerik.com/aspnet-core/upload/async

 

If you go there directly the link is

Scenario: Imagine you implemented upload widget within grid and it can upload multiple files. After you upload, you realize you need to delete one of the uploaded file. Currently you cannot choose to delete either of the uploaded multiple files in edit mode. It would be nice to display preuploaded files in upload widget when the grid is in edit mode, so that user can delete the files that are not necessary anymore.

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

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.

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.

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.
