Thanks for your reply!
Anyway in order to fix this, I changed the code inside the themes/datatables/js/datatables.js (delete_row() function) replacing the line
success_message(data.success_message);
with this
$('#list-report-success').slideUp('fast');
$('#list-report-success').html(data.success_message);
$('#list-report-success').slideDown('normal');
:)
Another possible way is just to modify themes/datatables/js/datatables.js (delete_row() function) replacing the line
success_message(data.success_message);
with...
form_success_message(data.success_message);
and change in the file assets/grocery_crud/js/jquery_pluins/config/jquery.noty.config.js
replacing the "report-success" div reference with "list-report-success" ...
But with this last method, on form validation (add/edit), you'll not get the error messages at the bottom of the form; only red border to the inputs....
