As already mentioned in the comments, you probably removed the private void listView_SelectionChanged(object sender, SelectionChangedEventArgs e)

Two solutions:

1) Remove reference

Go to BlankPage1 and look for the listview that is on line 16 and remove the reference from the SelectionChanged event.

2) Add reference

Go to the BlankPage1.xaml.cs file and add the following method:

private void listView_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
