    Is there a way to determine the event after binding?

    I am using HierarchicalDataSource : ObservableCollection when binding.

    Ulitimately, I am trying to programmatically expand all nodes after the treeview binding. And I can't seem to find the correct event to fire the expandall()

    Am I on the wrong path?

    Please advice.

    Hello Robert Anthony,

    In the Loaded event of the RadTreeView you can check the status of the ItemContainerGenerator.

    If the status is different than ContainersGenerated you can attach to the RadTreeView.ItemContainerGenerator -> StatusChanged event.

    Once the Status of the ItemContainerGenerator become ContainersGenerated you can use the ExpandAll method.

    Please let us know if you need more help on that.
