TreeMapLevels
7 Jun 20171 minute to read
The levels of TreeMap can be categorized into two types as,
- FlatLevel
- Hierarchical Level
Flat Level
GroupPath
You can use groupPath
property for every flat level of the TreeMap control. It is a path to a field on the source object that serves as the “Group” for the level specified. You can group the data based on the groupPath
in the TreeMap control. When the groupPath
is not specified, then the items are not grouped and the data is displayed in the order specified in the dataSource
.
GroupGap
You can use groupGap
property to separate the items from every flat level and to differentiate the levels mentioned in the TreeMap control.
