TreeMapFlatDataAdapter.GroupDataMembers Property

Gets or sets the names of data members of the data source used to group tree map items generated from the data source.

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

Expanded Syntax

Property value

Type: GroupDataMemberCollection
A collection of System.String values, specifying the names of data members.

Expanded Remarks

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.
