title: Difference between AjaxFileUpload and AsyncFileUpload in Asp.Net Ajax Control Tool Kit
body: <p>I have been learning how to use the different controls that the <strong>asp.net ajax  control tool kit</strong> provides.</p>
  
  <p><strong>I came across two controls that are very confusing to me:</strong> </p>
  
  <ol>
  <li><code>AjaxFileUpload</code> and 2.<code>AsyncFileUpload</code>.</li>
  </ol>
  
  <p>The 1 st control is pretty fine . I understood that AjaxFileUpload uploads the file <strong>with out having the post back</strong> unlike normal asp.net File Upload Control</p>
  
  <p>But, I <strong>was not sure what again is this AsynxFileUpload</strong>. I was not able to understand <strong>difference</strong> between them</p>
  
  <p>Can any one please clear me on this. If possible , any example</p>
  
  <p>Thanks</p>
