您是否有足够的列或水平内容来实现滚动？您的示例中的代码太多了，但却无法包含足够完整的代码。请简化代码示例，以便您提供的代码能够可靠地演示问题。ScrollViewer.CanContentScroll=True不应位于ItemsPresenter上，它应通过ListBox样式进行设置。它不起作用。我举了一个例子，你可以看到水平滚动是如何不起作用的。尝试在blend中打开您的项目。。。。然后右键单击你的对象和时间线窗口中的LBGameList。。。。然后选择Groupinto并在那里选择scrollviewer。所以它看起来是这样的哦，别忘了将ScrollViewer水平条设置为auto（自动）或visible（可见）。。。。我想它的默认值是禁用的。
