I have an expensive operation to determine if there are children for a node so I am determining if there are children asynchronously.
I have simulated LoadOnDemand with the TreeListView using a view model with a background worker. When the worker completes it's work it fires OnPropertyChanged for the collection and the tree then shows the expander.
Is there a way to show an animation in place of where the expander normally resides? I would like it to be similar to how the TreeView loading animation displays when used with IsLoadOnDemandEnabled. Right now my tree nodes show no expander until after the async call is complete and it is confusing to end users.
Thanks
