I have a bool property in my ViewModel called `IsConnected` and I would like to bind it to a TextBlock in my MainWindow. Rather than have the textblock read `true` or `false` I need it to say `Connected` or `Disconnected` instead. Forgive me because I'm new to WPF. If someone could give me a head start I can take it from there but I'm not sure how to figure out what I need.
