I cannot get DataGrid binding to work in the example bellow. Any clues on what's going on ?

推荐答案

ItemsSource绑定需要将Path(而非Source)设置为 persons .简单地将其表示为 {Binding person} 就可以解决问题(Path是标记中的默认属性)或显式地 {Binding Path = persons} .DataContext始终是继承的.

The ItemsSource binding needs to have Path set, not Source, to persons. Simply putting it as {Binding persons} would do the trick (Path is the default property in markup) or explicitly {Binding Path=persons}. The DataContext is always inherited.
