朋友您好，当用户还原或减小应用程序的高度或宽度时，我想将滚动查看器添加到整个页面，然后应启用滚动查看器。以便用户可以使用滚动查看器移动表单。 提前致谢。
当我通过滚动查看器时，当我“还原”或降低应用程序高度时无法启用

使用ScrollViewer，可以在比实际大小小的区域中显示内容。当ScrollViewer的内容不完全可见时，ScrollViewer会显示滚动条，用户可用来移动可见的内容区域。范围包括ScrollViewer的所有内容。内容的可见区域是视口。
请检查ScrollViewer官方document
使用ScrollViewer，可以在比实际大小小的区域中显示内容。当ScrollViewer的内容不完全可见时，ScrollViewer会显示滚动条，用户可用来移动可见的内容区域。范围包括ScrollViewer的所有内容。内容的可见区域是视口。
因此，如果内容大小大于ScrollViewer的实际大小，则会显示滚动条。我发现您已将网格高度设置为1000，如果ScrollViewer高度小于1000，则ScrollViewer将垂直滚动。为了确保ScrollViewer填充页面内容，您需要将ScrollViewer VerticalAlignment和HorizontalAlignment设置为Stretch。
<ScrollViewer VerticalAlignment="Stretch" HorizontalAlignment="Stretch" />
