If you modify a databound observable collection to navigationview menu/footer items and then modify that list later in the program, the ui will not update with the new items.

Ui now updates when binding source is updated.

• added source binding list change event handling for navigationview menu/footer items.
• Added collection action handling of menu/footer items.

Fixed stackoverflow due to recursive call from collection change event when updating from binding source.

Hi please look at (https://github.com/lepoco/wpfui/pull/1092) You don't need to add the items to another collection as it is an observable collection, any change to the collection will change the items.

[ioswald]

The initial items get added to the observable collection and update when you set the itemssource, but you aren't adding a binding to the itemssource; they're just being added from one to the other; so if the itemssource changes after the initial binding is done; the items do not update.
