A File Upload/Download Control/Component by Dart Communications

PowerWEB File Upload uses advanced Ajax techniques to transfer files from browser to web server while minimizing the server memory footprint. Typical file upload processes in ASP.NET require files to be uploaded and stored in memory before being exposed to the page cycle. File Upload allows you to stream files to disk, memory, or any Stream interface for advanced applications such as a direct file upload to an FTP server. Additionally, the look and feel of File Upload controls can be customized with custom fonts and images to seamlessly blend into your website design.

Compared to the native ASP.NET HtmlInputFile control, the PowerWEB Upload control:
- Can upload multiple files
- Is a visual control that can be styled
- Uses Ajax to upload files, eliminating the full-page refresh
- Streams files to memory, disk, or any other streaming interface (to eliminate large memory allocations on the server)
- Allows the user to cancel the upload at any time

Compared to competing products, PowerWEB File Upload includes advanced web controls that enhance your users' experience:

- True drag/drop/run development model is provided, automatically preparing the project web.config at design-time
- The Upload and OpenFileDialog controls allow users to select multiple files within a single dialog
- The Upload and ProgressPanel control can be styled and customized for any application
