是否可以直接访问CarouselViewControl中包含的列表视图？ 我有一个左右旋转的旋转木马，每页内都有一个列表视图。但是，由于ListView包含在CarouselViewControl中，所以我无法直接通过代码调用ScrollTo（）函数来访问它，而且ScrollTo函数也不能绑定。我还尝试通过FindVisualChildren扩展循环遍历所有呈现的控件，并且看起来当旋转木马呈现时，它不会将列表视图呈现为列表视图，因此我看不到任何可以滚动到特定位置的方式垂直位置。

我正在尝试创建一个字母选择器（类似于android音乐播放器上的那个），以便当用户单击一个字母时，它将它们带到列表视图中的那个位置。但是，它也必须位于轮播视图的内部，以便在其他页面之间滑动时显示不同的列表。

是否有任何其他方法可以实现这一目标？
