    public class DataSource : DependencyObject 
    { 
        public List<DataSource> Children { getset; } 
 
        public string Name { getset; } 
 
        public DataSource() 
        { 
            Children = new List<DataSource>(); 
        } 
    } 
    <Window.Resources> 
        <local:DataSource x:Key="DataSource"
            <local:DataSource.Children> 
                <local:DataSource Name="1"
                    <local:DataSource.Children> 
                        <local:DataSource Name="2"
                            <local:DataSource.Children> 
                                <local:DataSource Name="3"
                                    <local:DataSource.Children> 
                                        <local:DataSource Name="4"/> 
                                    </local:DataSource.Children> 
                                </local:DataSource> 
                            </local:DataSource.Children> 
                        </local:DataSource> 
                    </local:DataSource.Children> 
                </local:DataSource> 
            </local:DataSource.Children> 
        </local:DataSource> 
    </Window.Resources> 
    <telerik:RadTreeView ItemsSource="{Binding Path=Children, Source={StaticResource DataSource}}" IsEditable="True"
        <telerik:RadTreeView.ItemTemplate> 
            <HierarchicalDataTemplate ItemsSource="{Binding Path=Children}"
                <TextBlock Text="{Binding Path=Name}"/> 
            </HierarchicalDataTemplate> 
        </telerik:RadTreeView.ItemTemplate> 
        <telerik:RadTreeView.ItemEditTemplate> 
            <DataTemplate
                <TextBox Text="{Binding Path=Name, Mode=TwoWay}"/> 
            </DataTemplate> 
        </telerik:RadTreeView.ItemEditTemplate> 
    </telerik:RadTreeView> 
The above is the smallest reproduction I can find of this issue.
Editing any node (by pressing F2) brings up the TextBox as it should.  However that TextBox is empty and a BindingExpression error occurs (as visible in the output window):

System.Windows.Data Error: 40 : BindingExpression path error: 'Name' property not found on 'object' ''String' (HashCode=557208335)'. BindingExpression:Path=Name; DataItem='String' (HashCode=557208335); target element is 'TextBox' (Name=''); target property is 'Text' (type 'String')

Making the Name property a proper DependencyProperty has no effect.  The DataItem seems to be getting changed.  Curiously, if you change DataSource to NOT extend DependencyObject (ie make it just a CLR object), it works as expected.  I cannot change my real hierarchy this way.  Am I doing something wrong or should I log in PITS?
