wpf - 为什么我会看到与 WPF 中数据网格的 AreRowDetailsFrozen 和 HeadersVisibility 相关的绑定(bind)错误？

Question

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.DataGrid', AncestorLevel='1''. BindingExpression:Path=AreRowDetailsFrozen; DataItem=null; target element is 'DataGridDetailsPresenter' (Name=''); target property is 'SelectiveScrollingOrientation' (type 'SelectiveScrollingOrientation') System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.DataGrid', AncestorLevel='1''. BindingExpression:Path=HeadersVisibility; DataItem=null; target element is 'DataGridRowHeader' (Name=''); target property is 'Visibility' (type 'Visibility')

这些错误出现在 WPF 的即时窗口中。为什么会发生这种情况，我该如何阻止它？

This post here有此问题的解决方法的详细信息。这个对我有用:

在全局样式中添加如下代码:

<Style.Triggers>
     <Trigger Property="HeadersVisibility" Value="Column">         
          <Setter Property="RowHeaderWidth" Value="0" />
     </Trigger>
</Style.Triggers>
