Joining Data for use with Advanced Symbology

Discussion created by ccposton on Feb 6, 2013
I am trying to get Advanced Symbology to work with external data that relates to my parcel layer. I have created a sample where I use the ClassBreaksRenderer and set the LayerDrawingOptions on my ArcGisLocalDynamicMapServiceLayer. This works excellent for attributes/fields that are embedded in my layer. In my scenario the parcels will each have a unique id that relates to an id in an external sql database (this database contains all the useful data for each parcel). I need to be able to join a table in this database by id such that I am able to utilize the data for Advanced Symbology rendering. How can I achieve this?
