Good Day,
Getting the same error message in a span on
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
Even If I use or not using the below code 
https://johnnyreilly.github.io/jQuery.Validation.Unobtrusive.Native/AdvancedDemo/Tooltip.html
Why tool tip is not displayed.
I suspect the jquery, bootstrap and jquer.validate versions that I am using
https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/jquery.validate.js
Bootstrap css - 2.3.1
@model StudentMaintanance.Models.StudentViewModel
 
@{
    Layout = null;
}

    $("form").validate({
           
      showErrors: function(errorMap, errorList) {
 
          // Clean up any tooltips for valid elements
          $.each(this.validElements(), function (index, element) {
              var $element = $(element);
 
              $element.data("title", "") // Clear the title - there is no error associated anymore
                  .removeClass("error")
                  .tooltip("destroy");
          });
 
          // Create new tooltips for invalid elements
          $.each(errorList, function (index, error) {
              var $element = $(error.element);
 
              $element.tooltip("destroy") // Destroy any pre-existing tooltip so we can repopulate with new tooltip content
                  .data("title", error.message)
                  .addClass("error")
                  .tooltip(); // Create a new tooltip based on the error messsage we just set in the title
          });
      },
 
      submitHandler: function(form) {
          alert("This is a valid form!");
      }
  });
</script>
As you can see I have included the script from the above link
after pasting the script from the above link I am receiving just the alert("This is a valid form!");
Thanks,
