WPF: Slider doesnt raise MouseLeftButtonDown or MouseLeftButtonUp

Question

I tried this XAML:

Answer 1

Try using LostMouseCapture and GotMouseCapture.

    private void sliderr_LostMouseCapture(object sender, MouseEventArgs e)

    private void slider_GotMouseCapture(object sender, MouseEventArgs e)

GotMouseCapture fires when the user begins dragging the slider, and LostMouseCapture when he releases it.
