TreeMapItemStorage Class

Stores a collection of tree map items and provides them to a tree map control.

Namespace:DevExpress.XtraTreeMap
Assembly:DevExpress.XtraTreeMap.v19.2.dll

Expanded Syntax

Expanded Remarks

This class introduces the Items property, allowing you to specify the collection of tree map items.

For more information about Data Adapters, refer to the Providing Data topic.

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 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.
