body: <p>Is that possible to check is Scrollviewer scrolled to bottom?
  My XML code:</p>
  
  <pre><code>&lt;ScrollViewer x:Name="scroll" VerticalScrollBarVisibility="Auto" CanContentScroll="True"&gt;
      &lt;ListBox x:Name="chat" Height="290" VerticalAlignment="Top" Width="440" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.CanContentScroll="True" &gt;
          &lt;ListBox.ItemTemplate&gt;
              &lt;DataTemplate&gt;
                  &lt;Grid Width="410"&gt;
                      &lt;TextBlock TextWrapping="WrapWithOverflow" Margin="0,1"&gt;
                          &lt;Run Text="{Binding Name}" Foreground="{Binding Color}" FontWeight="Bold"/&gt;
                          &lt;Run Text=": "/&gt;
                          &lt;Run Text="{Binding Message}"/&gt;
                      &lt;/TextBlock&gt;
                  &lt;/Grid&gt;
              &lt;/DataTemplate&gt;
          &lt;/ListBox.ItemTemplate&gt;
      &lt;/ListBox&gt;
  &lt;/ScrollViewer&gt;
