树视图上下文菜单-将所选项目传递给命令？

Question

I'm wondering how to pass the selected item to a command from a treeview / HierarchicalDataTemplate ?

Here is the code that I have so far, it displays the context menu but I haven't bound the commands to it yet. The command binding is the easy part, but how do I tell which node it came from ?

<HierarchicalDataTemplate 
    DataType="{x:Type viewModel:UsersViewModel}" 
    ItemsSource="{Binding Children}">
    <StackPanel Orientation="Horizontal">
        <Image Width="16" Height="16" Margin="3,0" Source="Images\Region.png" />
        <TextBlock Text="{Binding UserName}">
            <TextBlock.ContextMenu>
                    <ContextMenu>
                        <MenuItem Header="Edit" />
                        <MenuItem Header="Delete"/>
                     </ContextMenu>
                </TextBlock.ContextMenu>
        </TextBlock>
    </StackPanel>
</HierarchicalDataTemplate>

Just {Binding} should be the whole item.

(To pass it to the Command bind the CommandParameter , in Execute and CanExecute it will become the method parameter (which you then need to cast to your item-type))
