Hello everybody,

I'm a starter at WPF, now i would like to make a WPF userControl library which include a Rating bar userControl. All the steps of creating the rating Bar has been done, however i would like to add a property RatingValue:

public static readonly DependencyProperty RatingValueProperty =
            DependencyProperty.Register("RatingValue", typeof(int), typeof(RatingControl),
            new FrameworkPropertyMetadata(0, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, new PropertyChangedCallback(RatingValueChanged)));

public int RatingValue
        {
            get { return (int)GetValue(RatingValueProperty); }
            set
            {               
                SetValue(RatingValueProperty, value);                
            }
        }

private static void RatingValueChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        {
         //... change the rating value
        }

that the user of my UserControl can modify by a value from 0 to 5 that are shown in a dropdown list (combo box) in the Properties windows (as some exist properties of Usercontrols like Visibility, windows style, background ...)

How can i do? Thank you very much in advance,
