J’ai une IHM, avec deux textbox, et un bouton OK.

Je voudrais que, quelque soit la place de mon curseur dans l’IHM,
l’action keyDown fonctionne. Pour l’instant, rien ne se passe, sauf si je recopie
le code pour les événements KeyDown des  texts box.

Qqn aurait une idée ?

Salut.

Il y a une autre méthode très simple :
Tu attaches une méthode à l'événement KeyDown de ta form, puis tu mets la propriété KeyPreview de ta form à true.

        public Form1()
        {
            InitializeComponent();
            this.KeyDown += new KeyEventHandler(Form1_KeyDown);
            this.KeyPreview = true;   // L'événement passe d'abord par ta form avant les textbox
        }

        void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            MessageBox.Show("Machin");
            e.Handled = true;   // L'événement est géré, donc ne déclanchera pas les autres événements KeyDown (de tes textbox par exemple)
        }

tu veux faire quoi exactement sur le keydown? si cest pour choper le "entrée" pour valider, tu a la propriété acceptbutton sur ton formulaire.
sinon, tu peux override la méthode ProcessCmdKey dans ton formulaire pour être notifié à chaque appui sur une touche quel que soit l'endroit ou tu es dans ton formulaire

Bon, après 30 minute de lute, j'ai réussi à faire  la méthode de Monsieur krimog. Merci leprov pour l'idée mais je crois que maintenant que ca marche, je n'y touche plus.
pas envie d'être curieux aujourd'hui
Merci bien à vous deux
