Binding string concatenation for ListBoxItem

I have a listbox and I want to show two properties from my object.
For one property it is pretty easy:

<ListBox.ItemTemplate>
   <DataTemplate>
     <TextBlock  Text="{Binding Name} "></TextBlock>                                        
    </DataTemplate>
</ListBox.ItemTemplate>

However I would like something like

Name - GroupName not just Name...

I know that it is easy, but I am confused. I don't know how to add two textblocks into the same level of the XAML hierarchy.

You can do this a couple of ways. One is with a MultiBinding and a StringFormat

<TextBlock>
  <TextBlock.Text>
    <MultiBinding StringFormat="{}{0} - {1}">
        <Binding Path="Name" />
        <Binding Path="GroupName" />
    </MutliBinding>
  </TextBlock.Text>
</TextBlock>

The second is option is to set the root element of your DataTemplate to something that can have more than one child, like a StackPanel and have to TextBlock controls each bound to the appropriate value.

<DataTemplate>
  <StackPanel Orientation="Horizontal">
    <TextBlock Text="{Binding Path=Name}" />
    <TextBlock Text=" - " />
    <TextBlock Text="{Binding Path=GroupName}" />
  </StackPanel>
</DataTemplate>

I prefer the first option.
