Problem is that I am not able to figure out how to trigger data template selector when task state is changed dynamically. I want to know how to use data triggers together with data templates. If this will not work out, i will explore other alternatives such as 1. Attached Property bound to task state. Any change will dynamically set data template. 2. Visual State Manager A DataTemplateSelector does not respond to PropertyChange
