Files begin uploading immediately after selection. This is enabled with
AutoUpload="true". No separate upload button is needed.
What you should see: pick any file and the upload starts immediately — no button press. When the queue completes, the page posts back, FileUploaded saves a server-side copy, and the confirmation below names its safe destination.
