Feature request: PropertyGrid - Parent Property Display does not update on Sub-Property Value Change


Let's say I have the following object:
public class MyCustomObject
public string MyString { get; set; }
public int MyInt { get; set; }
public bool MyBool { get; set; }
public override string ToString()
    return string.Format("{0} - {1} - {2}", MyInt, MyString, MyBool);
And then we have this class (referenceing the 'MyCustomObject' in a property)
public class MyViewModel
private MyCustomObject _myCustomObjectInstance;

public MyCustomObject MyCustomObjectInstance 
    get { return _myCustomObjectInstance; }
    set { _myCustomObjectInstance = value; }
public MyViewModel()
    MyCustomObjectInstance = new MyCustomObject() { MyInt = 4, MyString = "Four", MyBool = true };
I then set an instance of MyViewModel to be the SelectedObject of the PropertyGrid. The MyObjectInstance property shows up fine, and I am able to expand it to see the sub-properties. You'll also notice that the MyObjectInstance property is displayed using the ToString() representation, which is created via the 3 properties in the object itself. What I'm expecting is that when those sub-properties change, the display of the MyObjectInstance property should change as well... I believe this used to be taken care of via the 'NotifyParentProperty' attribute within the original WinForms PropertyGrid, but it doesn't appear to work in this case. Am I wrong (from a user's perspective) to expect this functionality?
I have attached an image to show you the behavior... Do you think this is a bug? Is it a feature request? It seems like it would be a trivial fix, but we all know where that line of thinking can take you ;-).
This is a great project. Your work is very much appreciated.
Thank you

This is a feature request. I will look into this and see what I can do.

That could help to find possible fixes

And I like that Multibinding approach where you don't need to create a custom property for the need:
