Probleme de dataGridView, pour ajouter une ligne
Bonjour,
J'ai un probleme concernant un datagridview en winform.
J'ai fais un code qui me permet de lister un nombre de chemin de fichier.
J'ai binder une Liste de StringValue (via : https://stackoverflow.com/questions/...idview-control
J'ai autorisé l'ajout de nouvelle ligne dans la binding source ainsi que pour le datagridview.
Je peux ajouter une première valeur sans soucis. Mais la ligne blanche me permettant d'ajouter des données n'apparait pas après.
Pourriez vous m'aider ?
Merci.
F.

y a t il du code derière cette methode ? dataGridView1.EndEdit();.
Et pourquoi n'utilises tu pas la propriété AllowUserToAddRows pour forcer le datagriview à ajouter une nouvelle ligne ?
