Better way to handle error on web app?

Question

HI Team   I have created some logic around handling error, but im not getting any error. The idea when a user leave @EditorFor must validate the message with image error. I have done this following, but its not working debug nothing, maybe missing something pls assist. // Model       [Required(ErrorMessage =  " This field is required" )]           [EmailAddress(ErrorMessage =  "Invalid email address" )]            public   string  Email {  get ;  set ; }      // View on Form       class = "form-group row" >                                    for = "Email"   class = "col-sm-2 col-form-label" >Email:                                     class = "col-sm-4" >                                       @Html.EditorFor(model => model.RegForm.Email,  new  { htmlAttributes =  new  { @ class  =  "form-control" , autofocus =  "autofocus" , placeholder =  "Email"  } })                                       @Html.ValidationMessageFor(model => model.RegForm.Email,  "" ,  new  { @ class  =  "text-danger"  })                                                                                // Javascript                              "text/javascript"  src= "~/Content/dist/js/jquery.validate.min.js" >                                        "text/javascript"  src= "~/Content/dist/js/jquery.validate.unobtrusive.min.js" >
