Databinding

I did some investigation into this for a while and it turns out that this is a known issue in Microsoft's binding code. This article explains it pretty well:

Apparently they have not fixed it yet. The gist is that if you look your console output you will see errors like:
System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Width; DataItem=null; target element is 'Code128Symbology' (HashCode=8717356); target property is 'Value' (type 'String')

Because of what Nick describes in that article, the symbology is not able to properly bind to the data context.

I've done some tweaking of our code and the only thing I've found that makes it work is if the BarCodeSymbology class inherits FrameworkElement. I'm going to look into it more and perhaps make this change for the next maintenance release. There will have to be a breaking change or two since making that base class change will make our current Measure method conflict with UIElement.Measure. I'll post an update on this shortly.

We've made the change to have BarCodeSymbology inherit from FrameworkElement for the next maintenance release. This works around the WPF data binding bug.

In addition, we have added a new QuickStart showing how BarCode can be used for data binding within a ListBox.

Thank you for your support!
