I finally found a solution that works for me. As I mention in the comment, Paul Stovell’s approach would not work. Instead I used a similar approach to add an attached property to the TextBlock, bound to the TextBlock’s DataContext, and attached properties on the runs, indicating which ViewModel properties they should be bound to: … Read more
