The user is allowed to select any files. Why can't we implement the same accept="image/png, image/jpeg"> so that only these files can be selected?

Ref: https://demos.telerik.com/kendo-ui/upload/initialfiles

 

TelerikUpload control is a good start. However, missing an important feature of initial files. When can we expect this feature to be added to the control?

accessibility issue - upload is not notifying files are chosen

Impacts screen reader users

[WCAG 1.3.1 level A] [WCAG 4.1.3 level AA]

tested using NVDA on chrome browser

input (type="file") status always reads as 'no file chosen' when one or more files have been chosen (correct when no files are chosen). 

on choosing a file to upload (so no file chosen yet), screen reader advises; web page title, chrome, page contents, file input status (same behaviour as default html 5 file input). On choosing a file a default browser html 5 file input will advise a file has been chosen. The list shown below the Telerik component is not known to a screen reader user

Accessibility issue

impacts keyboard user

[WCAG 2.1.1 level A]

tested using NVDA on chrome browser

the ability to remove, review, & navigate (with direction keys) each item chosen for upload is not directly accessible via a keyboard, To overcome this the user needs a screen reader to read line by line.  
At least, a screen reader user can do the following inside the list:

• be advised (when forcefully reading line by line); how many items in list, filename, file is incorrect or file size, (optional) reload button, and remove button.
• use 'del' key to remove an item. 

Right now we are hiding it based on styling. 

Would be nice to have a property to hide it.

We do this to provide a customized display of files uploaded.

In version 2.9.0 of the library there are two small spelling issues:

Scheduler_Recurrence_Editor_Frequencies_Monthly: Montly //Montly is written without "h"
Upload_InvalidMinFileSize: File size too small //Missing dot after the message (E.g. Upload_InvalidMaxFileSize has an ending dot).

This request is for the Upload component to allow using a named HttpClient for connecting to the Web API.  This would alleviate the need to enter authentication headers in the OnUpload event if the named HttpClient has already been configured for all of that at startup.  I see 2 potential options for this.  Either provide a string parameter that contains the name of the HttpClient that was set up at startup. This way when you instantiate an HttpClient, you can use a factory to create it by name.  Or provide an IHttpClient parameter where the user can directly pass in the client to the component.

I want to have the ability to prevent my users from dragging and dropping files in the Upload component via built-in API. A parameter like EnableDragDrop would be a good way to achieve the desired behavior. 

We need to support to upload large files (Bigger than 2.1GB). Typical data size we are dealing with is around 1 ~ 10GB

The current MaxFIleSize only support 2,147,483,648 (2GB) due to the use of type int.

Please change the type of MaxFileSize property of TelerikUpload control so that it support file uploading for more than 2.1GB.

Please consider a timeout setting for the Upload requests, similar to the XmlHttpRequest timeout.
