Issues with the way Microsoft implements databinding and datacontext forced a unplanned re-design of the channel selection control. Figuring the best way to select items from a list would be Microsoft's very own list box with multi-selection turned on. Unfortunately though, for whatever reason, while Microsoft provides a .net control for multi selection, they offer no way to bind to the selection in a MVVM enviornment. Thanks M$... So I made my own, and after some hurdles it seems to be working well.
