title: Track the upload progress while uploading file to azure blob
body: <p>I am uploading a video on my site by taking it by client using simple uploader then uploading to <code>azure blob</code> in code-behind using <code>blob.UploadByteArray()</code> , </p>
  
  <p>I want to track <code>upload progress</code> that how many bytes are uploaded out of total at that moment? Is there any API or workaround for that? </p>
  
  <p>I don't want to use third party up-loader or blob pusher etc.</p>
