Description

The LayerVisibilityChanged method is called when the visibility of a layer is changed interactively using the TOCControl.

If a layer (typically a raster layer) within a Globe is fully cached the original data source does not need to be present in order for the layer to display. To ensure that the TOCControl changes the visibility of a cached layer the LayerVisibilityChanged method ensures the Globe changes the GlobeLayerProperties.
