Accepted answer
Why do you want to show the validation after AJAX fail..You should show validation message on button click means before sending AJAX request to server.

Validation depends on below condition:

->if you are using strongly type view:

You need to define validation attribute like required, max length, min length etc.. and bind that model in your view page. When you submit the button it automatically validates inputs and display error message.

->If you are not using strongly type:

You need to check it manually by taking value from textboxes. if it is blank then display error message it before sending AJAX request.
