CloudUploadFile
CloudUploadFile is part of the RadCloudUpload control. It is the entity that tracks all upload-related tasks. This class does not upload a file to the cloud. It encapsulates a provider, a file name and a file stream and handles all upload-related tasks, such as progress-tracking and cancellation. The CloudUploadFile object is expected to be the DataContext of the RadCloudUploadListItem.
The CloudUploadFile class does not open or dispose the stream. The disposal should be handled by the owner of this object.
