workaround:
Extract the ControlTemplate for the TreeListViewRow and set the Style explicitly or remove the local Style setter.

Expanded TreeListViewRow cannot be collapsed when select a child node and SelectionMode is set to "Expanded".

Steps to reproduce:
1. Expand the root node
2. Select a child node
3. Try to collapse the root node

Asynchronous mode for ExpandAllHierarchyItems()

Items are expanded when they match the filtering criteria.

Once I added the filterdescriptor, the tree started to expand itself
and when I put a break point in RowIsExpandedChanged event handler
the treelistviewrow's IsExpanded property is already true

Can you have a look at the attached sample application
and try to achieve the following:
1. keep the on demand load (so only loadchildren when user clicked on the arrow to expand)
2. apply filter only on the expanded nodes
