public IEnumerable<MapItem> DescendantsBottomUp { get; }

Public ReadOnly Property DescendantsBottomUp As IEnumerable(Of MapItem)

Field Value

This property enables you to retrieve a flattened collection of all items contained by the Map, for example if your map contains a Folder, the DescendantsBottomUp collection will contain all of the MapItems contained by the Folder, as well as the Folder itself.

The same holds true for any IMapItemParent object in the Map: the IMapItemParent.ChildItems are included in the returned DescendantsBottomUp collection.

Use this property if you need to recurse all items in the Map, including those that are not direct children of the Map. In this respect, the DescendantsBottomUp property differs from Map.ChildItems that only returns a collection of the Maps immediate children.

The order of the items in the returned collection is different to the order of items in the Descendants collection. Both properties return the same number of items but DescendantsBottomUp returns a collection where IMapItemParent objects are added after their associated ChildItems. Conversely using the Descendants property will return a collection where IMapItemParent objects are added before their associated ChildItems.
