Hi,
I have a treeview bound to an observablecollection, each node has an observablecollection of children and so on for the entire hierarchy. Is there a way to have the treeview node expand automatically as children are added to the object that it is bound to?
Thanks,

I forgot to mention that all the tree items are loaded on demand.
The complete picture is:
1) User uses a seperate interface to search for an item.
2) Item is located somwhere within the hierarchy of the tree, none of the tree nodes have been loaded yet.
3) Using a collection of identifiers I want to expand a sequence of nodes to expose the item the user searched for.
Since my tree is already bound to a hierarchy of observablecollections I thought it would be easier to just figure out how to have nodes expand automatically when children are added.

Hello Ben,
I have prepared a small project that demonstrates how add an item to a node and expand the treeview to that node. The treeview in the demo has a 3-level hierarchy. Have a look at the sample project and let me know how this works for you.
