Joe,
You can add the uploader into your control at each page life cycle ,
Uploader up;
protected override void OnInit(EventArgs args)
{
base.OnInit(args);
up=new Uploader();
up.FileUploaded+=new UploaderEventHandler(up_FileUploaded);
mycontrolholder.Controls.Add(up);
}
private void up_FileUploaded(object sender, UploaderEventArgs args)
{
}
Regards,
Terry
