Property Value

Type	Description
SelectedGroupCollection	The collection of selected groups’ paths.

Remarks

The group path consists of data items that this and parent groups visualize. The item order within this collection specifies the nesting level within the Tree Map or Sunburst. For example, the following image demonstrates two selected groups: the “50 - 60 years” and the “70 - 80 years” | “United States” subgroup:

The group path contains a collection with one value equals “50 - 60 years” in the first case. And the second path includes two values: “70 - 80 years” and “United States”.

Note that the data items’ concrete type depends on the controls’ data adapter type:

Data Adapter Type	Data Item Type
TreeMapFlatDataAdapter SunburstFlatDataAdapter	Data items are values of data source fields that the adapter’s GroupDataMembers property specifies. The data item order corresponds to the group order in the data member collection.
TreeMapHierarchicalDataAdapter SunburstHierarchicalDataAdapter	Data items are data objects that the hierarchical data adapter provides. The item order is from the parent item to the selected item.
TreeMapItemStorage SunburstItemStorage	TreeMapItems or SunburstItems that the item storage contains. The item order is from the parent item to the selected item.
