C# 一些mvvm问题-了解当前正在编辑实体的视图
我试图规划一个基于mvvm的基础设施，我决定通过vm将视图直接绑定到实体。（vm将保存实体引用，绑定将是o entity.propertyName…） 现在我遇到了一个问题，当用户开始编辑一个视图中的字段时，我想锁定（使之为只读）绑定到正在编辑的实体的所有其他视图 所以我的问题是：C# 一些mvvm问题-了解当前正在编辑实体的视图,c#,wpf,mvvm,C#,Wpf,Mvvm,我试图规划一个基于mvvm的基础设施，我决定通过vm将视图直接绑定到实体。（vm将保存实体引用，绑定将是o entity.propertyName…） 现在我遇到了一个问题，当用户开始编辑一个视图中的字段时，我想锁定（使之为只读）绑定到正在编辑的实体的所有其他视图 所以我的问题是： 为了能够知道谁（什么视图）首先开始编辑，以及他何时完成编辑，我需要在设计中做哪些更改。。如何知道不是来自ui的更改（不锁定任何内容）这实际上取决于您的程序结构。我有一些类似的需求，我在primaryshell视图中这

基本上，我将visualstatemanager数据绑定到主viewmodel上的一个属性，该属性将根据我创建的枚举触发各种可视状态。我从Karl Shifflets Stuff应用程序中得到了最好的帮助。这实际上取决于您的程序结构。我有一些类似的需求，我在primaryshell视图中这样做了
