Does anyone know if a UniqueValueRenderer can be based on multiple fields? If yes, what would the syntax look like? and if no, is there another way to symbolize based on multiple fields? Thanks
You can implement your own renderer as described in post# 8 in this thread: http://forums.arcgis.com/threads/22939-feature-layer-not-binding-to-the-Unique-Value-renderer. For your case though, you will need Attributes[] and Info.Values[]. For every attribute, you need to check if it is equal to any of the info.Values[]. If all attributes have been matched with an info.Value, then you can return that info.Symbol.
