Listview select "active" item

Question

Possible duplicate:
Select ListBoxItem if TextBox in ItemTemplate gets focus

I have ListViewone related to ObservableCollection( Listview.ItemsSource). Listview provides several text fields that are bound to the properties of objects in the observed collection.

I would like to have the following functions: when the user focuses on the text field, the corresponding item in the list should be selected.

I tried things with ContainerFromElement, ContainerFromItem, etc., but I can not get this "simple" functionality to work.

Any ideas ...

IsKeyboardFocusWithin ItemContainerStyle:

<ListView ItemsSource="{Binding}">
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Style.Triggers>
                <Trigger Property="IsKeyboardFocusWithin" Value="True">
                    <Setter Property="IsSelected" Value="True" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.ItemTemplate>
