WPF hierarchical table

Can anyone explain how the HierarchicalDataTemplate works

  • What controls support the HierarchicalDataTemplate?
  • What is needed to support the HierarchicalDataTemplate control?

UPDATE

  • What causes the TreeView to render the parent and child nodes when the same Hierarchical DataTemplate in the HeaderedItemsControl calls only the parent that will be displayed?

Such control must be of type HeaderedItemsControl or derived from it. Existing wireframe controls are MenuItem, ToolBar, and TreeViewItem.

HeaderedItemsControl PrepareContainerForItemOverride - HierarchicalDataTemplate.
