Binding style property outside itemsource?

Question

I've a combobox like this:

   <ComboBox x:Name="CountryMenuComboBox" 
        ItemsSource="{Binding Countries}">

        <ComboBox.ItemContainerStyle>
            <Style>
                <Setter Property="IsEnabled" Value="{Binding IsRemoving}" />
            </Style>
        </ComboBox.ItemContainerStyle>

what I need to do is enable or disable the items inside the combobox using the property IsRemoving, but this property isn't located inside the itemsource Countries, so I need to access outside the itemsource. How can I do this for a style?

Answer 1

Is IsRemoving a property of the parent viewmodel that owns the Countries property? If so, try <Setter Property=“IsEnabled” Value=“{Binding DataContext.IsRemoving, RelativeSource={RelativeSource AncestorType=ComboBox}}” />
