我的用户控件设计。该控件包含许多行和列，其中包含子网格，行和列。其中一个最内行包含一个ListView，其水平和垂直滚动条设置为自动。
我能够查看listview的水平滚动条以及最外面的网格，但是我无法查看listview的Vertical Scroll bar，但外网格工作正常。
这是同样的xaml。

可能是我发布了巨大的xaml，因为我不确定整个用户控件到底出了什么问题。
有一个，请查看我的xaml并告诉我在哪里需要更改rowHeight或其他一些东西。
任何帮助都非常感谢。
答案 0 :(得分：1)
WPF的ScrollViewer为其子元素提供了无限空间 - 我认为这会阻碍您查看ListView的垂直滚动条。让我们分析一下你的情况：
<RowDefinition Height="Auto" />）计算。最后一行将占用滚动查看器提供的剩余无限空间。*。解决方案可能是限制此行的高度，但提供GridSplitter以便用户可以更改高度。 @pushpraj指出的另一个解决方案（当我写这篇文章时）是限制列表视图的高度。
如果您有任何其他问题，请随时提出。
