Visual Basic (Declaration)
Public ReadOnly Property DescendantsBottomUp As IEnumerable(Of MapItem)

Field Value

An IEnumerable collection of all descendant MapItems in the Folder.


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

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

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