Hi,
Is there a quick way to expand a branch to the leaves programmatically for a load on demand scenario?
Thanks ... Ed

Hello Ed,
I already answered your question in the ticket thread. However, I am posting it also here.
"The GetItemByPath method and the bring into view support in general, will find the searched item only if is presented in the items source of the treeview control. When the load on demand feature is enabled the searched item is not yet added in the tree and the method cannot find it.
In order to achieve your requirement, instead of using the load on demand event, you can move the method that gets the data in the view model. You can see how to do this in the How to Expand and Select Item with Load on Demand Enabled help article."
