J'ai créé un formulaire bootstrap et j'utilise le paramètre 'required' sur un contrôle pour utiliser la validation html5 lorsque je clique sur le bouton submit.
Lorsque je clique sur le bouton d'envoi, la bulle de validation apparaît pendant une seconde et disparaît. Je ne suis pas sûr de la raison pour laquelle cela se produit. J'utilise runat="server" sur les contrôles car j'ai besoin d'y accéder à partir de la page codebehind.
J'ai essayé plusieurs options mais toujours rien.
Une version réduite de la page ci-dessous :
