推荐答案

不幸的是，DataGrid 的列定义没有继承 DataContext，因为它们是不是可视化树的一部分，因此您不能直接绑定到 ViewModel.您需要采用一种解决方法，例如 这篇文章:

Unfortunately, the column definitions of the DataGrid don't inherit the DataContext, because they're not part of the visual tree, so you can't bind directly to the ViewModel. You need to resort to a workaround such as the one described in this article:

<DataGrid.Resources>
    <local:BindingProxy x:Key="proxy" Data="{Binding}" />
</DataGrid.Resources>

...

<DataGridTextColumn Header="{Binding Data.MyTitle, Source={StaticResource proxy}}"/>
