Hi this solution works for me. Just override Slider class and bind to FinalValue in xaml.

public class ExSlider : Slider
{
    public double FinalValue
    {
        get { return (double)GetValue(FinalValueProperty); }
        set { SetValue(FinalValueProperty, value); }
    }

    public static readonly DependencyProperty FinalValueProperty =
        DependencyProperty.Register(
            "FinalValue", typeof(double), typeof(ExSlider),
            new FrameworkPropertyMetadata(0d,
                FrameworkPropertyMetadataOptions.BindsTwoWayByDefault));

    protected override void OnThumbDragCompleted(DragCompletedEventArgs e)
    {
        base.OnThumbDragCompleted(e);
        FinalValue = Value;
    }

}
