Cette option entraîne le rendu du code HTML susceptible de ne pas être conforme aux normes d’accessibilité. Pour plus d’informations, consultez Accessibilité dans Visual Studio et ASP.NET.

Flow 1

Les éléments sont affichés sans structure de tableau. Le balisage rendu se compose d’un span élément et d’éléments séparés par br des éléments.

UnorderedList 2

Les éléments sont affichés sans structure de tableau. Le balisage rendu se compose d’un ul élément qui contient des li éléments.
Ce champ est nouveau à partir de ASP.NET 4 et est une option valide uniquement pour les contrôles et RadioButtonList les CheckBoxList contrôles.

OrderedList 3

Les éléments sont affichés sans structure de tableau. Le balisage rendu se compose d’un ol élément qui contient des li éléments.
Cette valeur est nouvelle à partir de ASP.NET 4 et est une option valide uniquement pour les contrôles et RadioButtonList les CheckBoxList contrôles.
