Bonjour,

Il m'arrive quelque chose de curieux.

J'ai un richtextbox dans mon application qui n'affiche qu'un seul caractère par ligne. Je n'arrive pas à voir pourquoi.

Je vous remercie de m'éclairer.

Cordialement

    Ensure that the content you're trying to display in the RichTextBox is correctly bound or assigned. If the binding is incorrect or the content is not set properly, it could lead to unexpected display behaviour.
