TreeMapFlatDataAdapter Class

The data adapter that provides flat data to a tree map.

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

Expanded Syntax

Expanded Remarks

This data adapter introduces the DataSource property that allows you to specify the data source of the adapter, and the DataMember, LabelDataMember and ValueDataMember properties, allowing you to specify the data members whose values are used as an item, item's label and item's value.

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

Expanded Example

To provide flat data to a TreeMap, create a TreeMapFlatDataAdapter object and assign it to the TreeMapControl.DataAdapter property. Then, specify the adapter's DataSource, LabelDataMember and ValueDataMember to configure the data source object and which data members should be used to generate tree map items. If you need to group generated items, add the name of a data member whose values should be used to group items, to the GroupDataMembers collection.
