//backend
protected void btnUpload_Click(object sender, EventArgs e)
{
    if (FileUpload1.HasFile)
    {
        if (System.IO.Path.GetExtension(FileUpload1.FileName) == ".xls" || System.IO.Path.GetExtension(FileUpload1.FileName) == ".xlsx")
        {
            FileUpload1.SaveAs(Server.MapPath("~/upload/temp/Forecast.xls"));
