c# - 删除listview滚动条时wpf窗口宽度大小不起作用

Question

我有一个使用 .NET 框架 3.5 版的 VS 2008 开发的 WPF 项目。初始窗口宽度设置为 680，SizeToContent 仅设置为“宽度”。此窗口的网格面板中放置了 3 个 ListView 控件。前 2 个网格都有一个指定宽度的列。第三个 ListView 控件没有指定任何列的宽度。当 ListView 控件最初填充数据时，窗口会正确调整大小。如果附加数据进入第三个 ListView，则窗口会相应地缩小或扩大宽度。但是，如果第一个或第二个 ListView 容器增长或缩小 - 特别是如果通过垂直增加窗口大小来移除滚动条，则窗口的宽度不会正确更新。

这是我的窗口和 ListView 控件的 XAML 代码：
