You have explained a little, I hope you do it in a WPF way ...

Create a property IsSelectedin your data elements, then specify a style for yours ListBoxItemthat will select them when enabled IsSelected:

<ListBox.ItemContainerStyle>
    <Style TargetType="ListBoxItem">
        <Setter Property="IsSelected" Value="{Binding IsSelected}"/>
    </Style>
</ListBox.ItemContainerStyle>

Then change the property on your data items and raise the event OnPropertyChanged.
