Can LayerDrawingOptions render only part of features on one layer?

Discussion created by huhao.esri on Dec 3, 2012
With Class LayerDrawingOptions, I can now change the rendering of a dynamic layer. The question is, instead of changing the rendering of all features (all polygons if it is a polygon layer), can I just change part of them? For example, keep the one clicked by user unchanged, and then change the rendering for all the rest.
