I am getting data in JSON and storing in List by

List<Product> rootObject = JsonConvert.DeserializeObject<List<Product>>(e.Result);

and after that, I am displaying data in ListBox by

  productlist.ItemsSource = rootObject;

My xaml file:-

<ListBox Height="600" HorizontalAlignment="Left" Margin="5,91,0,0" Name="productlist" VerticalAlignment="Top" Width="441"
             SelectionChanged="productlistselectionchanged">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal" Height="132">
                    <!--    <Image Source="{Binding Path=http://callme4.com/images/classifieds/ad_images/IMG_20130728_132750.jpg}" Height="73" Width="73" VerticalAlignment="Top" Margin="0,10,8,0"/> -->
                    <StackPanel Width="370">
                        <TextBlock Text="{Binding title}" Foreground="#FFC8AB14" FontSize="28" />
                        <TextBlock Text="{Binding city}" TextWrapping="Wrap" FontSize="24" />
<TextBlock Text="{Binding realdata}" TextWrapping="Wrap" FontSize="24" />
 <TextBlock Text="{Binding gender}" TextWrapping="Wrap" FontSize="24" />
 <TextBlock Text="{Binding age}" TextWrapping="Wrap" FontSize="24" />
                        <TextBlock Text="{Binding price}" TextWrapping="Wrap" FontSize="24" />
                    </StackPanel>
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
This is working fine.
But i have a condition in textblock.
if ( realdata == 1)
gender and age should be display and price should be hide.
else
price should be display. and Gender with age should be hide.

Please help me.
