Answer 1

Added a flag to indicate dragging and only send out value changed events when the slider is being dragged.

 public class CustomSlider:Slider
{

    public bool IsDragging { get; protected set; }
    protected override void OnThumbDragCompleted(System.Windows.Controls.Primitives.DragCompletedEventArgs e)
    {
        IsDragging = false;
        base.OnThumbDragCompleted(e);

    }

    protected override void OnThumbDragStarted(System.Windows.Controls.Primitives.DragStartedEventArgs e)
    {
        IsDragging = true;
        base.OnThumbDragStarted(e);
    }

    protected override void OnValueChanged(double oldValue, double newValue)
    {
        if (!IsDragging)
        {
            base.OnValueChanged(oldValue, newValue);
        }
    }
}
