TreeMapItemCollection Class

A collection of TreeMapItem objects.

Namespace:DevExpress.XtraTreeMap
Assembly:DevExpress.XtraTreeMap.v19.1.dll

Expanded Syntax

Expanded Remarks

This class is used by the TreeMapItem.Children and TreeMapItemStorage.Items properties.

Expanded Example

To manually provide data for a TreeMap, assign a newly created instance of the TreeMapItemStorage class to the TreeMapControl.DataAdapter property. Then, create several objects of the TreeMapItem class or its descendant class, specify their TreeMapItem.Label and TreeMapItem.Value properties, and add them to the TreeMapItemStorage.Items collection.

Note – to create a group, you will need to add a new TreeMapItem and fill its TreeMapItem.Children collection with tree map items.
