protected void UploadXML(object sender, EventArgs e)
     {
         string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
         string filePath = Server.MapPath("~/Uploads/") + fileName;
         FileUpload1.SaveAs(filePath);
         string xml = File.ReadAllText(filePath);
         string constr = ConfigurationManager.ConnectionStrings["dbConnection"].ConnectionString;
         using (SqlConnection con = new SqlConnection(constr))
         {
             using (SqlCommand cmd = new SqlCommand("InsertXML"))
             {
                 cmd.Connection = con;
                 cmd.CommandType = CommandType.StoredProcedure;
                 cmd.Parameters.AddWithValue("@xml", xml);
                 con.Open();
                 cmd.ExecuteNonQuery();
                 con.Close();
             }
