I am using a VS2012 and making a WPF application.  I am currently working through the details.  I am trying to Databind:

public enum ServerUpdateGroup
        {
            alpha = 1,
            beta = 2,
            beta2 = 3,
            cmobile = 4,
            cweb = 5,
            cwebmobile = 6,
            test = 7,
            triage = 8,
            zone1 = 9,
            zone2 = 10,
            zone3 = 11,
            zone4 = 12
        }

This to a ComboBox and I am unable to create a CollectionViewSource for the enumerator.  I am not even sure that is the way to go.  Here is the rest of my current code:

I am not sure I am headed in the right direction.  Any guidance would be greatly appreciated.
