Lakshmi,

 

Please check this sample :

 

 <script type="text/javascript">
 var uploader=document.getElementById('<%=Uploader1.ClientID %>');
 function CheckBrowsingTask()
 {
  var iobj=uploader.internalobject;
  var task=iobj._browsingtask;
  if(task==null)return;
  var file=task.file1;
  if(file==null)return;
  if(file.getAttribute("myinit")=="1")return;
  InitMyFileElement(file);
 }
 function InitMyFileElement(file)
 {
  file.setAttribute("myinit","1");
  file.style.backgroundColor="red";
  file.style.color="blue";//not works..
 }
 setInterval(CheckBrowsingTask,100);
 </script>

 

This sample refer the internal implementation object,

So it may stop work in future version (if we change that implementation)

 

Regards,

Terry
