    Response.Write(bts.Parent.Parent.GetType().ToString());
    if (e.CommandName.ToLower() != "upload")
    {
        return;
    }
    FileUpload fu = bts.FindControl("FileUpload4") as FileUpload;//here
    if (fu.HasFile)
    {
        bool upload = true;
        string fleUpload = Path.GetExtension(fu.FileName.ToString());
        if (fleUpload.Trim().ToLower() == ".xls" | fleUpload.Trim().ToLower() == ".xlsx")
        { …
