The NeatUpload™ ASP.NET component allows developers to stream uploaded files to storage (filesystem or database) and allows users to monitor upload progress. It is open source and works under Mono's XSP/mod_mono as well as Microsoft's ASP.NET implementation. It features several custom controls, including:
MultiFile allows all users to select multiple files to upload and allows Flash 8+ users to select multiple files from a single file selection dialog.
ProgressBar displays the upload progress either inline or in a popup.
UnloadConfirmer prevents users from accidentally interrupting an upload by leaving the page.
