WPF binding on generic list

Question

In my WP8 project, using MVVM, I bind an object to the View. That object has a generic list which I need to bind on a LongListSelector . Since I cant convert my list to observable, how can I bind it and have a TwoWay update?

Example of my object:

Class: Person

Properties:

• ID - int
• Name - string
• Groups - List of Groups . This is the property I need to bind on the LongListSelector

.

## UPDATE 1: ##

In short my problem is that I have an object with a List as navigation property (not observable collection). What is the Best Practice when you want to bind that List Navigation Property on the View.

Answer 1

Thanks to all comments from the guys, I ended up that it was inevitable after all to insist with generic list. I changed my list to ObservableCollection and everything is ok now.

I guess the answer credits should go to Clemens, Cédric Bignon and tanuj_loop
