Hi,
as on my own yesterday post, I'm still facing the Tutorial 3 scenario.
I've made the diagram create my derived "OrgChartNode" instances, both programmatically and through UI interaction.

I've extended also the generic.xaml file by adding controls which bind to dependency properties (e.g. "FullName" in OrgChartNode).
One of the dependency proprties I've added is a collection declared as IList<IMyListItem>.
The genric.xaml structure has been provided with a ListBox control that binds to the above collection property.

To test the code I've populated programmatically the above list during object (OrgChartNode) creation and then the OrgCharNode control properly displays both the items when rendered.

Then I've tried to modify the list after object construction by adding a new list item through a button.

The problem is that, this time, the OrgChartNode isn't refreshed as I would expect by the mean of its binding and I still see the old two items in the list box.

Am I taking something wrong? What should I do to "refresh" the OrgChartNode listbox after modification?

Cheers,
baba
