How does one grab the binding in order to force an update on a RadComboBox control?
MyRadComboBox.ItemsSource = MyObservableCollectionOfACustomClass;
MyRadComboBox.DisplayMemberPath = "Description";
Then, I try to grab the binding in a different control's event.
var binding = BindingOperations.GetBindingExpression(MyRadComboBox, RadComboBox.ItemsSourceProperty);
if (binding == null) return; // This is always null
binding.UpdateTarget();
