Hi Jackie, I am getting a little confused by all this. I am actually trying to dynamically add a copy of a layer that already exists in the map. You see, I already have a layer from the "Arteries.FeatureSource" in my map. I just want to check out how dynamically created layers can be added.
So I just copied the FeatureClass and Geometry from the layer in the Studio, and I also referred to the devguide Hydrography example. Still I have no clue. Could anyone take out a little time and explain it to me?
