RegularExpressionValidator, classe

Donne au contrôle la capacité de vérifier si la valeur d'un autre contrôle correspond à une expression régulière fournie.

public class System.Web.UI.MobileControls.RegularExpressionValidator : 
   System.Web.UI.MobileControls.BaseValidator

Notes

Cette classe se comporte de la même façon que le contrôle ASP.NETSystem.Web.UI.WebControls.RegularExpressionValidator.

Par défaut, les contrôles Command d'un formulaire déclenchent les contrôles validateurs du formulaire afin d'effectuer la validation nécessaire lorsque le formulaire est envoyé au serveur. Pour désactiver la validation automatique, affectez la valeur false à la propriété CausesValidation des contrôles Command.

Exemple

L'exemple suivant vous montre comment ajouter des propriétés d'expression régulière, telles que ValidationExpression et Text, par programme pendant le chargement d'une page.
