有了上篇文章的基础，这篇文章实现CustomControl就简单得多了，绝大多数代码也可以直接Copy过来使用。具体的创建CustomControl的步骤我就不累述了。
为了方便大家学习，请单击此处下载该程序的代码。
这次，Themes\Pager.xaml的代码如下：
其中省略号的部分用上篇文章中的Grid之间的代码代替。唯一需要修改的是：将上篇文章中，各个Label控件的MouseLeftButtonUp方法删除。
由于我曾经解释过，我们不建议在Themes目录下创建一个Pager.xaml.cs文件去处理各个Label控件的事件，所以我们需要在主程序中找到各个Label控件，并注册事件。
我们可以重写OnApplyTemplate事件，在这里去找到各个Label控件，并注册事件。
其它的代码就跟上一篇文章中的一样了。
