Dependency propertie validation

[columbos14927]

Hello, Ive created a dependency property:

class FrameworkElement : UIElement
{
public static readonly DependencyProperty NumberProperty;

    public FrameworkElement() { }

    static FrameworkElement()
    {
        FrameworkPropertyMetadata metadata =
            new FrameworkPropertyMetadata(Double.NaN,
                                          FrameworkPropertyMetadataOptions.AffectsMeasure);

        NumberProperty = DependencyProperty.Register("Number",//Propertie name
                                                      typeof(Double),//Data used by the prpertie
                                                      typeof(FrameworkElement),//The type that owns the propertie
                                                      metadata,//Meta data object
                                                      new ValidateValueCallback(FrameworkElement.IsNumberValid));//Validation callback

    }

    public Double Number
    {
        set { SetValue(NumberProperty, value); }
        get { return (Double)GetValue(NumberProperty); }
    }


    private static Boolean IsNumberValid(object value)
    {
        Double number = (Double)value;

        if ((number < 0) || (number > 100))
            return false;
        return true;
    }
}

and i added to it a validation callback. When i set an out of range number to that proprty i get an:ArgumentException. How can i do that instead of an exception the propertie will get some default value when i try to set out of range number? Thanks
