      <DataTemplate>
        <TextBlock TextWrapping="Wrap">
          <TextBlock.Text>
            <MultiBinding StringFormat="{} {0} {1}">
              <Binding Path="FirstName" Mode="TwoWay"/>
              <Binding Path="LastName" Mode="TwoWay"/>
            </MultiBinding>

        </TextBlock>
      </DataTemplate>
    </ListBox.ItemTemplate>
  </ListBox>

</Grid>

<Grid ColumnDefinitions="30* 70*">
  <!-- Main Content -->

  <!--<ContentControl prism:RegionManager.RegionName="{x:Static core:RegionNames.ContentRegion}"/>-->
  <view:Navigation/>

<Grid Grid.Column="1" RowDefinitions="Auto,Auto,Auto,Auto,Auto,Auto,*">
  
  <Label Content="Firstname" Margin="10 10 10 0"/>
  <TextBox Grid.Row="1" Text="{Binding SelectedFriend.FirstName,
    Mode=TwoWay}" Margin="10 0 10 10" TextWrapping="Wrap" MaxLength="50"/>

  <Label Grid.Row="2" Content="Lastname" Margin="10 0"/>
