WeightValuePath in Windows Forms TreeMap

The WeightValuePath of the tree map control is a path to a field on the source object that serves as the “weight” of the object.

Refer to the following code for specifying the weight value path.

TreeMap TreeMap1 = new TreeMap();

TreeMap1.ItemsSource = data.PopulationDetails;

TreeMap1.WeightValuePath = "Population";

NOTE

The specified field must be available in every subclass (object) defined in the hierarchical (nested) data collection.
