WPF Range Slider

I’m using Marlon Grech’s Avalon Controls Library Range Slider.  It’s a 2 thumb slider with a middle section, so its really 3 thumb. The middle piece will slide the range up or down.

Its quite full featured and comes with a good demo app:

It does have a funky way of letting the lower bound go through the upper bound and vice versa:

This doesn’t happen in the sample app that comes with the controls, so it could just be my problem.

I’m considering using Josh Twist’s Range Slider.  It worked nicely on the first try, but its more of a demo than a full fledged control.
