Valence Renderer

Description:

This sample renderer allows the user to display simple junctions based on the number of connected edges. The renderer demonstrates how to create a custom renderer with an associated property page that can be included in the list of available renderers in ArcMap. The code also demonstrates how to limit renderers to a specific set of feature classes (in this case, simple junctions). Lastly, this sample creates a working entry for the rendered layer that appears in the Table of Contents and will display in a legend.
Products:
