I checked the remove functions of the Upload Widget. As far as I understand: Any remove functionality reacts only on files "inside" the Upload widget. The widget itself is not persistent: You can upload files by the widget to get files into that list. You then can delete/remove them right away. After reload the page this file list is empty. The usual business case I know is: Customer do upload files on a day and want to delete it any other day or just later. I have such a case and create a unique ID for each uploaded file. I wonder if and how it is possible to use the Upload widget by sending this ID and triggering the removeURL handler. I've found some very old entries, one with trigger the remove event by "$(".k-delete").parent().click();" but nothing happens doing that.
The most simple way would be to add a file to be deleted on that file list and then call the removeURL handler.
Is there an easy way to do that or is it better to use a separate AJAX call?
