I added this column to a GridView (along with other columns), set the GridView to the view property of a ListView, and then databound the ListView to a collection of custom DataObjects.

For those who like a good WPF binding challenge: I have a nearly functional example of two-way binding a checkbox to an individual bit of a flags enumeration (thanks Ian Oakes, original MSDN post). The problem though is that the binding behaves as if it is one way (UI to DataContext, not vice versa). So effectively the check box does ...

Is it possible to deploy a WPF windows application in such a way that the xaml files can be manipulated at run-time? If possible, I would imagine this would work similar to an asp.net application that can deploy the .aspx pages as content, which are then compiled just-in-time at run-time. I'd like to allow the simple layout of a screen...
