title: HTML Embedded PDF's & onload
body: <p>I'm embedding a PDF in a web page with the following html :-</p>
  
  <pre><code>&lt;object id="pdf" classid="clsid:CA8A9780-280D-11CF-A24D-444553540000" width="1024" height="600"&gt;
      &lt;param name="SRC" value="/GetDoc.ashx?SOID=&lt;%=Html.Encode(Model.OrderID)%&gt;" /&gt;
      &lt;embed src="/GetDoc.ashx?SOID=&lt;%=Html.Encode(Model.OrderID)%&gt;" width="1024" height="600"&gt;
          &lt;noembed&gt; Your browser does not support embedded PDF files. &lt;/noembed&gt;                     
      &lt;/embed&gt;
  &lt;/object&gt;
  </code></pre>
  
  <p>The PDF's can be a little slow to load so I'd like to hide the object and display a loading message / gif until it's fully loaded so the user isn't looking at a blank screen. </p>
  
  <p>All I really need is a way of telling when the object is fully loaded. I've tried the 'onload' event of the  but it never seems to get fired. </p>
  
  <p>I'm beginning to think it might not be possible, but it never hurts to ask...</p>
