我可以在XAML中将元素的对象引用分配给另一个元素的对象引用吗？

Question

我正在使用WPF实现轮播用户界面。 当滑动轮播时，我使用VisualStateManager来更新轮播中元素的位置。

将元素移动到其目标兄弟位置的位置后，我想重新分配元素引用，以便VisualStateManager可以继续将项目移动到下一个位置的行为，而无需维护每个元素的运动。

我遇到的问题是，我认为我需要重新分配元素引用到兄弟元素的引用，该元素刚刚重新定位了轮播中的一个元素的位置（类似于链接列表）

问题：

我可以在XAML中将元素的对象引用分配给另一个元素的对象引用吗？ 或者更好的是，有没有更好的方法来使用XAML实现轮播？

XAML：
