❔ How to bind data to a listbox that doesnt come out of a database?

Title pretty much says it all.
I have the following code but it doesnt work:

<ListBox x:Name="list_ideologies" Margin="0,0,1031,10" Grid.RowSpan="2" ItemsSource="{Binding data.ideologies}"/>

<ListBox x:Name="list_ideologies" Margin="0,0,1031,10" Grid.RowSpan="2" ItemsSource="{Binding data.ideologies}"/>
