title: VisualStateManager not setting attached properties Grid.Row and Grid.ColumnSpan in UWP application
body: <p>I'm trying to change some attached properties using the VisualStateManager in a Windows 10 Universal App project but the setters aren't working. It's not setting the attached properties of my TopBarGrid element. </p>
  
  <p>If you look below I'm using the parentheses notation in order to change the <code>Grid.Row</code> and <code>Grid.ColumnSpan</code> properties. But when I run the app, the properties are not being set when I enlargen the width. I'm expecting the Grid to move to that position.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;Grid&gt;
      &lt;VisualStateManager.VisualStateGroups&gt;
          &lt;VisualStateGroup&gt;
              &lt;VisualState x:Name="wideState"&gt;
                  &lt;VisualState.StateTriggers&gt;
                      &lt;AdaptiveTrigger MinWindowWidth="641" /&gt;
                  &lt;/VisualState.StateTriggers&gt;
                  &lt;VisualState.Setters&gt;
                      &lt;Setter Target="splitView.DisplayMode" Value="Inline"/&gt;
                      &lt;Setter Target="splitView.IsPaneOpen" Value="True"/&gt;
                      &lt;Setter Target="togglePaneButton.Visibility" Value="Collapsed"/&gt;
                      &lt;Setter Target="appHeader.Margin" Value="0,0,0,0"/&gt;
                      &lt;Setter Target="PaneHeader.Margin" Value="6,12,0,0"/&gt;
                      &lt;Setter Target="TopBarGrid.(Grid.Column)" Value="0"/&gt;
                      &lt;Setter Target="TopBarGrid.(Grid.RowSpan)" Value="2"/&gt;
                  &lt;/VisualState.Setters&gt;
              &lt;/VisualState&gt;
              &lt;VisualState x:Name="narrowState"&gt;
                  &lt;VisualState.StateTriggers&gt;
                      &lt;AdaptiveTrigger MinWindowWidth="0" /&gt;
                  &lt;/VisualState.StateTriggers&gt;
                  &lt;VisualState.Setters&gt;
                      &lt;Setter Target="splitView.DisplayMode" Value="Overlay"/&gt;
                      &lt;Setter Target="togglePaneButton.Visibility" Value="Visible"/&gt;
                      &lt;Setter Target="PaneHeader.Margin" Value="60,12,0,0"/&gt;
                      &lt;Setter Target="searchForInfoBox.Width" Value="270"/&gt;
                  &lt;/VisualState.Setters&gt;
              &lt;/VisualState&gt;
          &lt;/VisualStateGroup&gt;
      &lt;/VisualStateManager.VisualStateGroups&gt;
      &lt;Grid.RowDefinitions&gt;
          &lt;RowDefinition x:Name="TopRowHeight" Height="80"/&gt;
          &lt;RowDefinition Height="*"/&gt;
          &lt;RowDefinition Height="60"/&gt;
      &lt;/Grid.RowDefinitions&gt;
      &lt;Grid.ColumnDefinitions&gt;
          &lt;ColumnDefinition Width="Auto"/&gt;
          &lt;ColumnDefinition Width="*"/&gt;
      &lt;/Grid.ColumnDefinitions&gt;
      &lt;Grid x:Name="TopBarGrid" Grid.Row="0" Grid.ColumnSpan="2"&gt;
          &lt;toolbars:TopHorizontalToolBar/&gt;
      &lt;/Grid&gt;
      &lt;Grid x:Name="LeftBarGrid" Grid.Column="0" Grid.RowSpan="2" Visibility="Collapsed"&gt;
          &lt;toolbars:VerticalToolBar /&gt;
      &lt;/Grid&gt;
