Public NotInheritable Class GroupLayer Inherits CompositeLayerWithTables Implements ArcGIS.Desktop.Core.IMetadataInfo, ILayerContainer, ILayerContainerEdit, IMetadataSource, IStandaloneTableContainer, IStandaloneTableContainerEdit, System.ComponentModel.INotifyPropertyChanged
Remarks
To create a GroupLayer, you must call CreateGroupLayer() method of the LayerFactory class, instead of directly using a constructor.
Example
Remove empty groups
{
//Get the group layers
IReadOnlyList<GroupLayer> groupLayers = map.Layers.OfType<GroupLayer>().ToList();
//Note: Run within a QueuedTask
foreach (var group in groupLayers)
{
if (group.Layers.Count == 0) //No layers in the group
{
//remove the group
map.RemoveLayer(group);
}
}
}
