Access Denied error when uploading file from IE

Hello,

 

I am uploading file using Fileupload control in ASP.Net. Instead of direct use of fileupload, Popup opens using JS and it fill the name to control but when I going to upload this using any Postback then either fileupload control lost file or Access Denied error is Alerted. Here is my code :

 

 

function openWin(msg) {
    $("#fu").click();
}

 

 

 

It is working in Firefox, Chrome but not working for IE.  is that any other way to make it work in IE ?

Please Suggest.....

 

Thanks
