I'm using a treeview with containerbinding. One of the properties in the collection is CheckState which is two way bound to my data collection. I need to do some processing when the Check/Uncheck event fires, but when a user checks/unchecks a checkbox the event is fired before the data itself is updated. Is there a way around this? I'm thinking about forcing an update of the binding, but I don't know how to retrieve the binding expression of the checkbox.

Hi Jorn,

Can you process the data in your view model entirely? This is the best approach in an MVVM application. I am not sure what exactly is your logic, but you can take a  look at this tutorial demonstrating how to implement a tri-state check box logic entirely in the view models. You can use similar approach in your application as well.
