如何解决WPF中TabControl操作失效问题？

Question

当我在窗体中，放入TabControl（里面有TabItem1和TabItem2），再放一个Button。Button的Clicked事件中，改变TabItem2的IsSelected属性为True。这时，按下按钮，TabItem2显示。------------------------------当我在TabItem1中，放入一个ComboBox后，再按Button，TabItem2则不会显示。我知道这一点是WPF路由事件惹的祸，请问大家如何解决该问题？

<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="150,46,0,0" Name="button1" VerticalAlignment="Top" Width="75" />Click 事件呢？ 你没指定啊Click="button1_Click"
