IGraphicsLayer Interface

Provides access to members that control the Graphics Layer.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

A graphics layer can be associated with another layer in the map; when that other layer changes visibility, the graphics layer can change visibility also. Use the IGraphicsLayer interface to manage this.

The IGraphicsLayer interface also has methods to activate and deactivate the graphics layer. When a graphics layer is active, it is the current annotation target.
