我在列表视图中遇到了列表视图问题，在列表视图中有一个组合框。
我有一个listview（名为＆＃39; lvUsers＆＃39;），某些列包含组合框，每个列包含一个listview（名为＆＃39; lvArmamento＆＃39;）。
当我以编程方式设置主列表视图的ItemsSource时，lvUsers，它没有任何问题。
但是当我尝试在XAML中使用listview＆＃39; lvArmamento＆＃39;时，它不会显示任何内容。
这是我的XAML代码：

感谢阅读。祝你有愉快的一天。
答案 0 :(得分：3)
armamento需要是一个财产
public List<Armamento> armamento { get; set; }
