如何在MVVM中的另一个类中处理One类中属性的属性更改事件

Question

Say I have description property in one class:

public string Description
{
    get
    {
        return _description;
    }

    set
    {
        _description = value;
        RaisePropertyChanged("Description");
    }
}

I would like to monitor the change in these value in some other type. How do I wire up?

Answer 1

You can subscribe the event PropertyChanged.

myModel.PropertyChanged+=(s,e)=>{ /* your handler here */};

as the @stijn comment point, unsubscribing can be required if the model became unused to avoid memory leaks.
