So, I am sure that I am not approaching this correctly and would like some advice. I am trying to create a drop down of Font selections. I can define it in the XAML (and it recognizes the initial selection value), but when I click the drop down arrow, I receive an Unhandled Exception (Code 4004) System.ArgumentException: Value does not fall within the expected range. I am assuming this is because I don't have a "Binding" mapping for the value into the Content control. How would I setup the Display and Value bindings inline?
