interaction bouton formulaire

Hello les noob,

.Net Framework 4.5.2
MVC Version=5.2.3.0

Donc j'ai une page avec un formulaire et un bouton.
J'aimerais savoir comment à partir de ce bouton je peux afficher quelques chose dans un label ou autres en dessous du bouton en fonction des données entrées par l'utilisateur en input.
