    Hi, 

    In short I want to know how to access the value of a parent's sibling attribute in the MVVM observable object. I do have a solution but I would like to know if the best option for me to use.

    Thanks,
    Grant

    Hi Grant,

    Using the ViewModel is the correct way of accessing an object in this scenario. Note that you could get reference to the object directly:
    viewModel.person.name

    Morning Konstantin, 

    Thanks for the confirmation, although I'd rather avoid using a direct reference so as to no loose any dependency links.

    See

    Thanks so much,
    Grant

    You could also traverse up the tree as well.

    Or can you tell me why this would be a bad idea? then you wouldn't have to reference the viewmodel by name directly. As you know where you are in the object it's just a case of going up the levels to come back down.
