TreeMapControl.DataAdapter Property

Gets or sets the data adapter for a TreeMap control.

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

Expanded Syntax

Property value

Type: ITreeMapDataAdapter
An object of a class implementing the ITreeMapDataAdapter interface.

Expanded Remarks

Expanded Example

To provide flat data to a TreeMap, create a TreeMapFlatDataAdapter object and assign it to the DataAdapter property. Then, specify the adapter's TreeMapFlatDataAdapter.DataSource, TreeMapFlatDataAdapter.LabelDataMember and TreeMapFlatDataAdapter.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 TreeMapFlatDataAdapter.GroupDataMembers collection.
