Injecting (INotifyPropertyChanged functionality) to an instance of an class
- by no9
Hi !
I have a class that implements INotifyPropertyChanged.
I create an instance of a class in some viewModel.
Is it possible to remove this functionality from the class and inject it after the instance was created? I heard that ICustomTypeDescriptor would make this happen, but i dont know how to use it.
public class C : ICustomNotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public int _id;
public string _name;
public int Id
{
get { return _id; }
set
{
if (_id == value)
{
return;
}
_id = value;
OnPropertyChanged("Id");
}
}
public string Name
{
get { return _name; }
set
{
if (_name == value)
{
return;
}
_name = value;
OnPropertyChanged("Name");
}
}
public void OnPropertyChanged(string name)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null)
{
handler(this, new PropertyChangedEventArgs(name));
}
}
