在点击事件中引用WP7边框元素

Question

I have a WP7 app that is using bing maps and I have pushpins for multiple locations. On tapping the pushpin I have a tap event that displays a border with some text. To hide the text I'm using a tap event for the map control which sets the border visibility to collapsed:

private void map_Tap(object sender, GestureEventArgs e)
    {

        this.border.Visibility = Visibility.Collapsed;
    }

Now if I am going to be using multiple borders and texts, I'm going to have to set the visibility multiple times like so:

this.border.Visibility = Visibility.Collapsed;
this.border2.Visibility = Visibility.Collapsed;
this.border3.Visibility = Visibility.Collapsed;

So I created a resource for the border in order to refer to just one border.

<phone:PhoneApplicationPage.Resources>
<Style x:Key="BorderStyle" x:Name="border" TargetType="Border" >
        <Setter Property="Background" Value="Black" />      
    </Style>
</phone:PhoneApplicationPage.Resources>

And I set the resource in the pushpin

<my:Pushpin.Content>
                <Border Style="{StaticResource BorderStyle}" >

But now when I refer to the border in the map_Tap event I get a System.Windows.Style does not contain a definition for 'Visibility' because the border is no long referenced as a UIElement(at least that's how I'm understanding this). How can a make a style for the border element and still reference it as an element?

I would like to suggest you this approach and this might help you for some other tasks too.

You use a list of type border and add all the border elements into it. Now whenever you want to manipulate all the elements you can have a foreach loop and access any property you would like example item.Visibility and you can manipulate it as you like. This will even help you sort them out so that you can manipulate any specific border.
