SelectionChanged event

Sep 19, 2008 at 9:12 AM
I am using the Presentation Model to display a Grid. Using the approach outlined in this article: 
I have a presentation model that binds to a DataTemplate that contains the grid. I can display the data fine and edit, however I want to use the event aggregation mechanism to update a different grid when a row is selected in the first grid.
How do I get hook up the SelectionChanged event in the grid so I can then publish the change?
