Question

我的查看代码如下。我想添加一些功能，比如当我双击DataGrid的任何单元格时，它应该将该值从单元格反映到标签命名为＆＃34; Notification＆＃34;你能告诉我怎么做吗？因为我是初学者，在我自己的代码中给出工作示例会对我有所帮助。感谢。

有两种方法可以管理数据网格单元格的双击，如下所述： How do i handle cell double click event on WPF DataGrid, equivalent to windows DataGrid's Events?

因此，请不要使用您的，但更喜欢使用其他绑定来更新通知标签。

因此，在您的xaml文件中，您将拥有类似的内容：

<Label Name="Notification" Content="{Binding NotificationContent}"/>

在您的viewModel中，您将在触发命令时更新NotificationContent属性。

希望它有所帮助。
