DependencyProperty.Register(
"Value", typeof(decimal), typeof(NumericUpDown),
new FrameworkPropertyMetadata(MinValue, new PropertyChangedCallback(OnValueChanged),
new CoerceValueCallback(CoerceValue)));
private static object CoerceValue(DependencyObject element, object value)
{
decimal newValue = (decimal)value;
newValue = Math.Max(MinValue, Math.Min(MaxValue, newValue));
return newValue;
}
private static void OnValueChanged(DependencyObject obj, DependencyPropertyChangedEventArgs args)
{
NumericUpDown control = (NumericUpDown)obj;
RoutedPropertyChangedEventArgs<decimal> e = new RoutedPropertyChangedEventArgs<decimal>(
(decimal)args.OldValue, (decimal)args.NewValue, ValueChangedEvent);
control.OnValueChanged(e);
}
