[WPF] ListView: SelectedItems ritorna sempre 1 elemento

[robertino_salemi]

Buonasera,
sto utilizzando la ListView


<ListView x:Name="chkListViewSampleStatus" HorizontalAlignment="Left" VerticalAlignment="Top"
DataContext="{StaticResource DomainDataViewModel}" ItemsSource="{Binding SampleStatus}" IsSynchronizedWithCurrentItem="True" Width="727" Height="50">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=ScrollContentPresenter}}"
ItemWidth="{Binding (ListView.View).ItemWidth, RelativeSource={RelativeSource AncestorType=ListView}}"
MinWidth="{Binding ItemWidth, RelativeSource={RelativeSource Self}}"
ItemHeight="{Binding (ListView.View).ItemHeight, RelativeSource={RelativeSource AncestorType=ListView}}" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.View>
<GridView ColumnHeaderContainerStyle="{StaticResource myHeaderStyle}">
<GridView.Columns>
<GridViewColumn Width="20">
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox Tag="{Binding Name}" HorizontalContentAlignment="Stretch" Margin="-5" Padding="-5"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding ValueDescription}" Width="110" />
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>


Vedo i miei elementi composti da label + checkbox, seleziono 2 o più elementi, ma (nel code behind) se provo a vedere gli elementi selezionati:

chkListViewSampleStatus.SelectedItems


Vedo sempre e solo 1 elemento.

Perchè?

Grazie.
