This post will be a step-by-step guide to using the ToogleButtonListBoxBehavior that I have created inside of the OpenLightGroup.Common Library.
To follow this tutorial you will need to download the latest version of the OpenLightGroup.Common Library and add a reference to the included dll file. We will also be using Microsoft Blend; however, the behavior can be added in Visual Studio just as other behaviors.
