How to get text from textBlock during SelectionCha

Question

I am try to get a text from my TextBlock during item select from my Listbox.

Here is my code for listbox in my xaml file..

<ListBox x:Name="listBox" Height="535" Margin="7,0,12,0" 
      SelectionChanged="selectedItem" 
      ItemsSource="{Binding}">

    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <toolkit:WrapPanel FlowDirection="LeftToRight" 
                ItemWidth="215" ItemHeight="215" />
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>

    <ListBox.ItemTemplate x:Uid="info">
        <DataTemplate>
            <StackPanel>
                <Border>
                    <Image HorizontalAlignment="Left" Margin="6,6,0,0" 
                        Name="image1" Stretch="Fill" 
                        VerticalAlignment="Top" 
                        Source="{Binding imageSource}" />
                </Border>
                <TextBlock x:Name="path" Foreground="Transparent" 
                    Text="{Binding imagePath}"/>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>

</ListBox>

For my c# code i am using a selectionChangedEvent method that will handle tap event but i can not figure out how to get content of my TextBlock element.

private void selectedItem(object sender, SelectionChangedEventArgs e)
{
    //I need to take the content of my textblock w/c carry the path for
    //my image to be use to share using ShareMediaTask.    
    //path = the content of my textblock

    var task = new ShareMediaTask();
    task.FilePath = path;
    task.Show();
}

I would really appreciate any help.

Answer 1

If it's sent from the textblock, it would be your sender ... so you can do something like

var text = ((TextBlock)sender).Text;

Otherwise, you'll have to reference the property that it's binding to ...
Why, oh why will you name your textblock path ?? it'll confuse the hell out of everybody ... call it TextBlockPath, this way it's not ambiguous with just a path ...

Answer 2

if imagePath is a Property of a class, try this

var item = listBox.SelectedItem as className; // like ShareMediaTask

var task = new ShareMediaTask();
task.FilePath = item.imagePath;
task.Show();
