You can check this with this way:

...
scrollViewer.ScrollChanged += OnScrollChanged;
...

private void OnScrollChanged(object sender, ScrollChangedEventArgs e)
{
   var scrollViewer = (ScrollViewer)sender;
   if (scrollViewer.VerticalOffset == scrollViewer.ScrollableHeight)
          MessageBox.Show("This is the end"); 
}
