You cannot disable the autofill programatically. It is browser behaviour, and it differs per browser. You can disable it per browser, but that is up to the client.

According to this answer, you can add hidden dummy textboxes before the actual ones to throw off the autocomplete.

<input style="display:none" type="text" name="fakeusername"/>
<input style="display:none" type="password" name="fakepassword"/>
