  <ListBox Grid.Column="1" Grid.Row="4" Grid.RowSpan="2" Margin="0,0,1,0" MinHeight="80" Name="lbThemes" SelectionMode="Multiple" IsEnabled="True">                         
<ListBox.ItemTemplate>
   <DataTemplate>
      <StackPanel>
        <CheckBox x:Name="ThemeCheckbox" />
        <TextBlock Text="{Binding Path=label, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
       </StackPanel>
    </DataTemplate>
 </ListBox.ItemTemplate>
</ListBox>
