outlook 2016 tracking status not updating - Wpf treeview not updating

My App has a Tab Control, Tree View is on one tabpage, the other tabpage has a datagrid, it has some data selected from treeview.

When right click an item in datagrid, I want to locate the item on treeview.

), then I am able to find the item on treeview and expand its path.

I'm trying to display a list of items and their children in a Tree List View.

( Does it or doesn't support Hierarchical Data Template?
