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.
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>
e.g. for the file "Golf & Country Club.png" the file info name is "Golf & Country Club" which leads to an exception.
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).
