featurelayer - selection changed event

Is there an event in the silverlight API that will trigger when the featurelayer selection changes?

I can't find an event in this list that does this.

This post kind of helped me:

Looks like I should us PropertyChanged event with the e.PropertyName ="SelectedGraphics".

It is kind of troublesome with the event triggering multiple times for each selection change.

If you are using PropertyChanged event, keep in mind that SelectedGraphics or SelectionCount properties get changed when you select or deselect the graphic.

Are you using Editor to select your graphic? If yes, you can look at using Editor.EditCompleted event. When inspecting the affected graphics, you can check Graphic.Selected property.
