ListView.SelectedItems does not change when clicking a TextBox in the ItemTemplate

I have a ListView bound with an ObservableCollection. The Itemtemplate of the ListView is the following:

<ListView ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="True" PreviewMouseLeftButtonUp="ListViewClicked" PreviewKeyDown="NameBox_KeyDown">
    <ListView.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <Image Source="./Resources/DeleteIcon.png"/>
                <TextBox Text="{Binding Path=Name}"/>
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

This way I give the user the choice to either change the name of the element, or delete it from the list. I handle this two operations in code behind through the two event handlers attached to the ListView.

The problem is that when I click on the TextBox, the SelectedItems property of the ListView doesn't change and it points the last selected item. When I click on the image or on the free space around the selection change.

Now I have two questions:

  1. Is there an easy way to fix this behavior?
  2. Is it possible to get a reference to the collection item whose property is exposed by the TextBox?

One way to deal with this problem is to set Trigger to set IsSelected when keyboard focus is within ListViewItem

<ListView ... SelectionMode="Single">
    <!-- .... -->
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="IsKeyboardFocusWithin" Value="True">                        
                    <Setter Property="IsSelected" Value="True"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
</ListView>
