Setting e.sender.options.files?

[Grant]

Hi, 

Im basing this question on the Upload Confirmation Dialog (https://docs.telerik.com/kendo-ui/knowledge-base/upload-confirmation-dialog). If the user selects 'Cancel' all the existing files are visually cleared. After this I would like to re-add (visually) any existing files.

I've tried setting 'e.sender.options.files' to the initial file list, and while the widget data is updated, its not updated visually. See Dojo, https://dojo.telerik.com/odoDODUZ.

Note: Your original demo doesnt actually work, the upload continues to fail, however I've tested the behavior in my local environment, and it is as I've described.

Please advise, Thanks,
Grant

Hi Grant,

The files option of the Upload can be set only during initialization of the widget. Currently, there is no way to programmatically set new selected files (refresh the list of selected files) on the fly after the Upload has been initialized. This means that, if you want a different list of files to be displayed as selected, you need to initialize a new Upload and pass those new files to its files option.
