How to get string value from Listbox as user selected?

Question

I can't get string value from Listbox after selected one item.

In my Listbox I have the Image (blinding source) and TextBlock (blinding source).

My code at .xaml page:

        <ListBox Name="carListBox" Height="431" Canvas.Left="28" Canvas.Top="65" Width="446" SelectionChanged="ListBoxOnSelection">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <Image Name="brandImage" Source="{Binding Image}" Width="100" Height="150"></Image>
                        <Image Name="carImage" Source="{Binding Image}" Width="150" Height="150"></Image>
                        <TextBlock Name="textDisplay" Text="{Binding ShowDetail}" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

My code at .xaml.cs page (C#)

private void ListBoxOnSelection(object sender, SelectionChangedEventArgs args)

    {
       MessageBox.Show(carListBox.SelectedItem.ToString());
       string saveData = carListBox.SelectedItem.ToString();

    }

MessageBox can't show string value and I can't get value after user selected.

You have to somehow get the Car object before you can have access to it's properties.

Something like this:

private void ListBoxOnSelection(object sender, SelectionChangedEventArgs args)
{
 Car myCar=carListBox.SelectedItem as Car;
 if(myCar != null)
   MessageBox.Show(myCar.ShowDetail); //or any property.
}
