我会抽头事件设置为电网和经过XAML路径。事情是这样的：

XAML：

<ListView x:Name="itemListView" 
    Margin="0,4.714,10,0.429" 
    ItemsSource="{Binding Source={StaticResource itemsViewSource}}" 
    SelectionChanged="itemListView_SelectionChanged" Loaded="itemListView_Loaded" Grid.Row="4" > 

     <ListView.ItemTemplate> 
      <DataTemplate> 
       <Grid Height="110" Margin="6" Tapped="listViewItem_Tapped">      
        <Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" Width="110" Height="110"> 
         <Image Source="{Binding Image}" Stretch="UniformToFill"/> 
        </Border> 
        <StackPanel Grid.Column="1" VerticalAlignment="Top" Margin="10,0,0,0"> 
         <TextBlock Text="{Binding Title}" TextWrapping="NoWrap" FontFamily="Global User Interface"/> 
         <TextBlock Text="{Binding Subtitle}" TextWrapping="NoWrap"/> 
         <TextBlock Text="{Binding Description}" MaxHeight="60" FontFamily="Global User Interface"/> 
         <TextBlock Text="{Binding Description2}" MaxHeight="60" FontFamily="Global User Interface"/> 
         <TextBlock Text="{Binding Description3}" MaxHeight="60" FontFamily="Global User Interface"/> 
         <TextBlock Text="{Binding Description4}" MaxHeight="60" FontFamily="Global User Interface"/> 
        </StackPanel> 
       </Grid> 
      </DataTemplate> 
     </ListView.ItemTemplate> 
    </ListView> 

和INT后面的代码，你可以这样做：

private async void listViewItem_Tapped(object sender, TappedRoutedEventArgs e) 
     {   
       Grid gridElement = (sender as Grid); 
       //Get the stackpanel 
       Stackpanel stackPanelWithElements = gridElement.Children.ElementAt(1) as Stackpanel; 
       //get the first TextBlock  
       TextBlock titleTextBlock = stackPanelWithElements.Children.ElementAt(0) as TextBlock; 

       //Get the text of the textblock 
       String title = titleTextBlock.Text; 

       //Get the next text 
      TextBlock subTitleTextBlock = stackPanelWithElements.Children.ElementAt(1) as TextBlock; 
      String subTitle = subTitleTextBlock.Text; 

      //get the other elements ... 
     }
