<asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="300000"></asp:Timer>
        
   <script type="text/javascript">

       function showpop(msg, title) {
           debugger;
           // alert("ok");
           toastr.options = {
               "closeButton": false,
               "debug": false,
               "newestOnTop": false,
               "progressBar": true,
               "positionClass": "toast-bottom-left",
               "preventDuplicates": true,
               "onclick": null,
               "showDuration": "300",
               "hideDuration": "1000",
               "timeOut": "120000",

               "showEasing": "swing",
               "hideEasing": "linear",
               "showMethod": "fadeIn",
               "hideMethod": "fadeOut"
           }
           // toastr['success'](msg, title);
           var d = Date();
