WPF 怎么获取样式中定义的元素状态值

Question

我需要使用TreeView来制作一个图层面板，我定义了一个节点的样式

        <!--主节点样式-->
        <Style x:Key="TreeRootStyle" TargetType="TreeViewItem">
            <Setter Property="HeaderTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <Image Name="imgLayer" HorizontalAlignment="Left" Source="/Images/Sys/layer_layers.png" Width="16" Height="16" />
                            <TextBlock Name="txtLayer" Margin="5,0,0,0" HorizontalAlignment="Right" Text="Layers" />
                        </StackPanel>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
        </Style> 

绑定样式

 <!--图层内容-->
            <TreeView Name="treeLayers">
                <TreeViewItem Name="rootLayer" Style="{StaticResource TreeRootStyle}" Selected="Layer_Selected" />
            </TreeView>

然后我的需求是，当点击一个节点以后需要获取TextBlock的Text内容，我应该怎么做呢？就是在后台的Selected事件中获取内容
