RadTreeViewItem.RootItem not returning correct item

[Will]

The RadTreeViewItem.RootItem property used to return an item's highest ancestor node (as of version 2009.1103), but in the current version (2010.0309) it always returns a reference to itself. Does anyone else see this behavior?

Here's a very simple example:

    <StackPanel>
        <telerikNavigation:RadTreeView x:Name="tree"/>
        <TextBlock x:Name="msg"/>
    </StackPanel>

And the code behind:

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            RadTreeViewItem item1 = new RadTreeViewItem() { Header = "item1" };
            RadTreeViewItem item2 = new RadTreeViewItem() { Header = "item2" };
            RadTreeViewItem item3 = new RadTreeViewItem() { Header = "item3" };

            tree.Items.Add(item1);
            item1.Items.Add(item2);
            item2.Items.Add(item3);

            // item3.RootItem returns item1 in 2009.1103 version (CORRECT)
            // item3.RootItem returns item3 in 2010.0309 version (WRONG)
            msg.Text = "item3.RootItem is " + item3.RootItem.Header.ToString();

            tree.ExpandAll(); // <-- This also doesn't seem to be working
            item1.ExpandAll(); // <-- Neither does this
        }

Hello Will,

Thank you for the feedback. The same problem you observed was recently reported by another user. It seems that with the 2010 Q1 release we have introduced a bug that affects the RadTreeViewItem.RootItem property. The issue is still not schedule for a specific release, but we will definitely get to it as soon as our schedule allows us.
