Unable to bind to TokenizingTextBox SelectedItems

[lukedukeus]

Describe the problem

I have a TokenizingTextBox control that I would like to bind to like this:
Page.xaml:

                <controls:TokenizingTextBox
                    SelectedItems="{x:Bind Viewmodel.SelectedItems, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                    TokenDelimiter=","/>

PageViewModel.cs:

public List<string> SelectedItems {get; set;} = new List<string>();

However this is not possible because SelectedItems is not a dependency property, and you can only access it in the code behind.

Describe the solution

I'm not sure. That's why I'm asking here. Right now, the way I am doing it is by manually updating the variable in the code behind on the focus lost event.
