Depedency Properties

Hello,

Hi have this DepedencyProperty:

public Test Value
{
    get { return (Test)GetValue(TestProperty); }
    set { SetValue(TestProperty, value); }
}

public static readonly DependencyProperty TestProperty =
    DependencyProperty.Register("Value", typeof(Test),
        typeof(UC), new FrameworkPropertyMetadata(new PropertyChangedCallback(ChangeFlag)));

private static void ChangeFlag(DependencyObject source, DependencyPropertyChangedEventArgs e)
{
    string countryName = ((Test)e.NewValue).ToString();
    ((UC)source).btnTest.Content = countryName;
}

And on xaml:

<Button x:Name="btnTest" Content="{Binding Value}" Foreground="White"/>

And when I use my UserControl on my Form:

Xaml:

<local:UC x:Name="btnText" FontSize="36" Value="Valor1"/>

My enum:

public enum Test
{
    Valor1,
    Valor2,
    Valor3,
    Teste1,
    Teste2,
    MinhaCMB,
    Teste3
}

When I try this on code behind of my form:

btnText.Valor = Test.Valor3;

Nothing happens.

---------------------

Another question: How can I change "Valor" (my depedencyProperty) on code-behind of my UC.

Regards, ADAE.
