Hard to say without seeing your XAML, but you could bind each CheckBox‘s IsChecked property to the same thing:

<CheckBox.IsChecked>
    <MultiBinding Converter="{StaticResource MyConverter}">
        <Binding Path="."/>
        <Binding Path="SelectedItem" RelativeSource="..."/>
    </MultiBinding>
</CheckBox.IsChecked>

The converter (IMultiValueConverter) would then determine whether the first value matches the selected value, and return true/false accordingly.
