The UploadControl allows files from the client computer to be uploaded and saved on the server.
To learn more about the UploadControl and see it in action, refer to its online demos.
The UploadControl is realized by the UploadControlExtension class. Its instance can be accessed via the ExtensionsFactory.UploadControl helper method, which is used to add an UploadControl extension to a view. This method's parameter provides access to the UploadControl's settings implemented by the UploadControlSettings class, allowing you to fully customize the extension.
