KoolUploader supports accessing status of uploading files. While the file uploading, you can access information such as uploaded bytes, estimated time left, average speed, uploading percentage and so on.
You may register handle for OnUpdateProgress event and get most updated uploading status.
*Note: If you run this example in localhost, the uploading process would be too fast for KoolUploader to get status.
