Tag property null when data binding

Question

Can anyone see what is wrong with this? The Tag property is returning null however the Binding for Id property is definately returning an int value.

    <ListBox ItemsSource="{Binding ElementName=myDomainDataSource, Path=Data}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal">
                    <TextBlock Text="{Binding Path=Id, Mode=OneWay}" />
                    <HyperlinkButton Content="Edit" Tag="{Binding ElementName=Id, Mode=OneWay}" Click="Edit_Click"  />
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

and then...

    private void Edit_Click(object sender, RoutedEventArgs e)
    {
        ContentControl c = sender as ContentControl;

        // exception - c.Tag is null
        int id = (int)c.Tag;
    }

The Id property is showing a value on the UI, but doesn't seem to be getting stored in the buttons Tag property.

Nevermind, it should use Path and not ElementName.
