如何通知视图模型的所有属性已更改 [英] How to notify all properties of the view model has changed

问题描述

在MVVM模式中，如何通知视图模型的所有属性已更改?我不想调用所有属性的所有notifypropertychanged事件.

In MVVM pattern, how to notify all properties of the view model has changed? I don' t want to call all notifypropertychanged event of all properties.

我有一个实体类，并且在视图模型中，我将该实体的所有公共字段都写为公共属性.我想重新绑定新实体，只写一行代码以通知所有属性都已更改?

I have an entity class and in view model I wrote all of the public fields of the entity as public properties. I want to rebind new entity and just write a single line of code to notify that all properties has changed?

感谢您的帮助.

推荐答案

只需使用空字符串作为属性名称引发PropertyChanged事件:

Just raise the PropertyChanged event with an empty string as the property name :

OnPropertyChanged(String.Empty);
