Question

好吧我有一个父网格，其中有三个其他网格。问题是我在最后一个里面有一个Listview。在此网格中，滚动列表视图项目不起作用。但是如果我在中间网格中移动相同的列表视图，则滚动工作正如我想要的那样。我在这里错过了什么？如何使Listview滚动在最后一个网格中工作。这是代码片段。 TIA

这三个网格位于父网格中。 grid.projection仅用于为汉堡菜单设置动画网格。没问题。

Answer 1

网格的行定义对于它所在的行是自动的。如果列表视图与auto一起放在一行它不会滚动你必须使用，1 ，2 *等或固定的高度。

Answer 2

我最近发现当我将ListView放在一个带有<PlaneProjection/>的Container中时，滚动停止了工作。关闭PlaneProjection允许ListView再次滚动。这是你的问题吗？我现在正在寻找解决方案。

WinRT Listview滚动不在网格中工作
