Wpf listview binding not updating
In view Model add Observable Collection with Order Items, this collection should notified view about changes in it.
I have a project, where I bind a checkbox's Is Checked property with a get/set in the codebehind.
The binding is not to the property of the parent object, but to that specific instance of the collection itself.
EDIT I've just noticed, your left List Box is not updated because you have no Data Template set for a Person object.Observable Collection is one of the most useful classes in WPF and Silverlight data binding.
