My apologies, that approach isn't available yet (we're working on it now). In the meantime, you can still accomplish what you want by using the TreeView's CheckItem
As an example, let's say the TreeView's ItemsSource was ObservableCollection<HomeMenuItem>
, then you could do this:
private void MyTreeView_OnNativeControlLoaded(object sender, EventArgs e)
var treeView = sender as RadTreeView;
var allItems = treeView.ItemsSource as ObservableCollection<
var firstItem = allItems.FirstOrDefault();
I'm going to update the documentation as soon as possible to explain these methods.
