Custom Busines Rule for numeric property

Hello,

I've a Custom Rules that checks if the user entered a valid numerical value (Double.TryParse)

I override the AddBusinessRules Method and added the rule like this:

BusinessRules.AddRule(new Business.CustomRules.Numerical(PreislistePos.PreisNormalProperty));

It works fine, as long as the user enters a numeric value. If the user types in characters, the rule doesn't checks the entered value. And the Property Status will not be shown.

Property:

        public static readonly PropertyInfo<decimal> PreisNormalProperty = RegisterProperty<decimal>(c => c.PreisNormal);
        [Display(ResourceType = typeof(Asego), Name = "PreisNormalText")]
        public decimal PreisNormal
        {
            get { return GetProperty(PreisNormalProperty); }
            set { SetProperty(PreisNormalProperty, value); }
        }

XAML:

<csla:PropertyStatus x:Name="preisNettoStatus" Property="{Binding Path=PreisNetto, Mode=TwoWay}" Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Right" Margin="0,0,10,0" IsManipulationEnabled="True" DataContext="{Binding Path=CurrentSelectedPreislistePos}" />

Now my question is, how to "fire" the rule if a user enter a character value in the TextBox?

Thanks and kind regards

Kevin
