In how do I sample ,I test with TrackShapeFinishedEvent and DrawEditShapes.
test solution:
1. add map click event to map ( empty method)
2.run it.
3.draw feature
4.Edit feature ( EditOverlay.TrackMode = TrackMode.Edit )
5. click on feature you want to edit.
see result.
After step 5,a feature is in edit mode and then it will be back to EditOverLay.
I think TrackMode.Edit is use event client click that make collision between Edit Mode click and Map Click.
