Is it possible to join a Feature Layer to an in memory table or graphics layer in code and use the attributes from the resulting join for thematically styling the Feature Layer using a class break renderer for example?
This would allow a user to bring their own local data in and have it used to style an existing Feature Layer using new attributes.
So the steps would be:
- Existing Feature Layer
- User selects a local database file and imports the data in to a new table or layer
- Join the new table or layer to the existing Feature Layer
- Create renderer for the Feature Layer based on attributes from the new table or layer
