View Sample on GitHub

Add, remove, and reorder operational layers in a map.

Manage Operational Layers App

How to use the sample

Drag layers between the lists to add and remove them from the map. Drag layers within the lists to reorder them.

How it works

A map's OperationalLayers collection controls which layers are visualized. MapView automatically updates the visualization when the Map changes. A separate collection holds layers that have been removed from the operational layers.

Relevant API

  • Map
  • ArcGISMapImageLayer
  • MapView
  • MapView.OperationalLayers


Map, scene, operational, hide, remove, add
