谢谢。尝试在网格内容面板下添加以下代码：
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
如果您需要进一步的帮助，您可能需要粘贴整个xaml。我在数据透视项中使用ScrollViewer时遇到了类似的问题。问题在于ScrollViewer中的内容（网格）与数据透视项的高度相同，因此ScrollViewer实际上无法滚动任何内容。我通过使数据透视项的高度小于ScrollViewer中内容的高度来修复此问题。此问题是由于使用了多个ScrollViewer；当LongListSelector中的项超过控件的大小时，它具有默认的滚动机制，因此我们不需要在LongListSelector上显式放置ScrollViewer 在您的情况下，将有两个ScrollViewer，一个来自LongListSelector，另一个是显式放置的。所以滚动没有发生 因此，只需从所有透视项中删除ScrollViewer，并将Grid.Row属性设置为LongListSelector
