title: UWP Listview in Gridview not increasing
body: <p>I've got a GridView to display some data. Each of the GridView items is a ListView which is increasing during runtime.
  I'd like the GridView to increase as well - but it is only showing a scrollbar inside the GridView item.
  One further requirement would be that each GridView Item should be aligned on top of the item.</p>
  
  <pre><code>&lt;GridView ItemsSource="{Binding}" ScrollViewer.VerticalScrollBarVisibility="Disabled" Width="1080"&gt;
  &lt;GridView.ItemTemplate&gt;
      &lt;DataTemplate&gt;                     
          &lt;ListView ItemsSource="{Binding ListData}" HorizontalAlignment="Center"&gt;
              &lt;ListView.ItemTemplate&gt;
                  &lt;DataTemplate &gt;
                      &lt;Grid&gt;
                          &lt;Grid.ColumnDefinitions&gt;
                              &lt;ColumnDefinition Width="Auto"/&gt;
                              &lt;ColumnDefinition Width="Auto"/&gt;
                              &lt;ColumnDefinition Width="*"/&gt;
                          &lt;/Grid.ColumnDefinitions&gt;
                          &lt;TextBlock Text="&amp;#x1f382;"

                                  Margin="0,0,10,10"

                          &lt;TextBlock Text="{Binding NameString, Converter={StaticResource DataBindingDebugConverter}}" 
                                  Grid.Column="2"
                                  Margin="10,0,0,0"

                      &lt;/Grid&gt;
                  &lt;/DataTemplate&gt;
              &lt;/ListView.ItemTemplate&gt;

              &lt;/ListView.ItemContainerStyle&gt;
          &lt;/ListView&gt;
