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

Please implement an Id attribute for the Upload component. This will allows us to associate <label> tags to it and pass accessibility checks.

The upload status hangs on "Uploading..." if the Upload component is hosted in a Dialog and the OnSuccess event is used.

 

<AdminEdit>

As a workaround, you can host the Upload in a Window, where this issue is not present

</AdminEdit>

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?

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).

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.

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. 

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.

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.

Last working version of Telerik UI for Blazor (if regression)

No response

Please expose the modified date of the selected and uploaded files, similar to the standard Blazor <InputFile> component.

This request applies to both the FileSelect and the Upload components.

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