Remarks
To create a GroupLayer, you must call CreateGroupLayer() method of the LayerFactory class, instead of directly using a constructor.
Example
Remove empty groups
var map = MapView.Active.Map; if (map == null) return; //Get the group layers IReadOnlyList<GroupLayer> groupLayers = map.Layers.OfType<GroupLayer>().ToList(); foreach (var group in groupLayers) { if (group.Layers.Count == 0) //No layers in the group { //remove the group await QueuedTask.Run(() => map.RemoveLayer(group)); } }
