Wpf 编辑一个数据网格会改变另一个数据网格

两个WPF数据网格绑定到单独的ObservableCollection时出现了一个奇怪的问题

这是我的XAML：

我的问题是，当我编辑一个数据网格时，另一个的值也会改变。我尝试将两个网格的datacontext设置为各自的ObservableCollections，但发生了同样的事情。在这一点上，我觉得我对WPF数据绑定的工作原理相当熟悉，但在这个问题上我完全被难住了。感谢您的帮助。

看起来您的项目是通过引用而不是通过值添加到您的

可观察集合中的

这意味着两个集合都包含对内存中相同对象的引用，因此更新一个集合中的对象实际上是更新单个对象引用，这会导致另一个集合也更新
您已经将mp对象传递给了DataGrid。因此，不需要使用代码隐藏来传递集合

按如下方式更新绑定：

<Custom:DataGridTextColumn Binding="{Binding ElementName=gridShifts, Path=DataContex.WorkShifts[0].WCList Mode=TwoWay}" IsReadOnly="True"  Header="Work Center"/>



您还应该为数据源使用
CollectionViewSource
实例，如下所示。这是一个更干净的设计，以后可能会带来好处。
您能显示object
mp
的代码吗？（另外，如果要在code behind中设置
ItemsSource
，而不是绑定它，则不需要在父网格上设置
DataContext
）。我试图在我最初的帖子中简洁，就是这样。非常感谢你。
