TreeMapHierarchicalDataMapping Class

Information about data object mapping to a tree map item.

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

Expanded Syntax

Expanded Remarks

Expanded Example

To provide hierarchical data to a TreeMap, create a TreeMapHierarchicalDataAdapter object and assign it to the TreeMapControl.DataAdapter property. Then, specify the adapter's data source object using the TreeMapHierarchicalDataAdapter.DataSource property. To configure how hierarchical data should be converted to tree map items, use HierarchicalDataMapping objects. The HierarchicalDataMapping.LabelDataMember property allows you to specify a label data member, the HierarchicalDataMapping.ValueDataMember property - a value data member, the HierarchicalDataMapping.ChildrenDataMember property - a data member containing children items, and the HierarchicalDataMapping.Type property - the type of items on the current nesting level.
