    Server-side validation finds an error in some other user's entries when they attempt to upload a file they've selected.

    After the PostBack, the Upload file list is empty again. How do I preserve the list so the user need not enter it again? Do I have to programmatically save and restore it myself?

    Hi Dave,

    In this case I recommend that you use RadAsyncUpload. It has the ability to persist the selected files after postback when you use the PostBackTriggers property, as shown in this demo.
