Hi,
I am using the control on the xaml pretty much the same way as how it's been explained in the example (please refer to documentation), so I have hierarchial list as in following:
ExploreItem
{
<string> Header;
<List of ExploreItem> Children
}
but I load the Children Dyamically, so by that I mean I load the children when the CurrentItem is changed, the problem that I have is that I cannot get the UI to be notified when I populate the children, I have got PropertyChanged() event to raise for all properties that I thought of but no lock so far, so please advice how to fix it up.
Thanks,
Aran

Hi Aran,
I guess you're experiencing this problem because you're using a List to store your Children elements. When you bind something to a collection and you want to be able to change the items in this collection dynamically (note that I said the Items, not the collection itself, the PropertyChanged() event will help you if you change the whole collection(its reference), not when you change its items) you should use a collection the implements the INotifyCollectionChanged interface. I think that the only build in collection which implements this interface is the ObservableCollection, so you should always use it when you use bindings.
I've created a sample project so could you please examine it and if you have further questions feel free to ask.
Kind regards,

Hi,
It was my bad, I completely forgot to inherit from INotifyPropertyChanged, it was one of those days :)
Thanks for your help,
Aran
