Hi Rakhi,

To save data in DB as uppercase, server side ToUpper() is the only way to be sure, as mentioned above. This can be done in your server-side action when saving data.

Client side options are basically all covered in here: https://www.the-art-of-web.com/html/input-field-uppercase/, but in short, you'd need a JavaScript action in each input's onblur/onkeypress/on<X> event, where you replace the contents of input field with it's uppercase equivalent.

If you only need to show the data as uppercase, you can style your form by applying CSS style/class to all input fields: { text-transform: uppercase; }. This option is for looks only, data will be saved exactly as user typed it in.

Evil UX option would be to restrict the allowed characters in your inputs using html5 pattern attribute (pattern="[A-Z]"), but that doesn't guarantee evil users would not be able to input lowercase data as a revenge to your silly decisions.
