This API supports the product infrastructure and is not intended to be used directly from your code.

Occurs when the HierarchicalDataSourceControl has changed in some way that affects data-bound controls.

event EventHandler^ DataSourceChanged {
	virtual void add(EventHandler^ value) sealed = IHierarchicalDataSource::DataSourceChanged::add;
	virtual void remove(EventHandler^ value) sealed = IHierarchicalDataSource::DataSourceChanged::remove;
}

This member is an explicit interface member implementation. It can be used only when the HierarchicalDataSourceControl instance is cast to an IHierarchicalDataSource interface.
