title: Vertical and horizontal GridSplitter
body: <p>I have a grid and I am trying to put both vertical and horizontal GridSplitters.  It's my main grid and I would like it to be as fluid as possible.  </p>
  
  <p>On my second definition I get "Missing Grid.Column setter for non-first child"</p>
  
  <p>I've found loads of documentation on implementing one or the other.  I have found nothing suggesting that I can do both.  But, our industry is made of people wanting to push functionality.</p>
  
  <p>Here is my XAML:</p>
  
  <pre><code>&lt;Grid&gt;
      &lt;Grid.ColumnDefinitions&gt;
          &lt;ColumnDefinition Width="50*"&gt;&lt;/ColumnDefinition&gt;
          &lt;ColumnDefinition Width="5"&gt;&lt;/ColumnDefinition&gt;
          &lt;ColumnDefinition Width="50*"&gt;&lt;/ColumnDefinition&gt;
      &lt;/Grid.ColumnDefinitions&gt;
      &lt;Grid.RowDefinitions&gt;
          &lt;RowDefinition Height="50*"&gt;&lt;/RowDefinition&gt;
          &lt;RowDefinition Height="5"&gt;&lt;/RowDefinition&gt;
          &lt;RowDefinition Height="50*"&gt;&lt;/RowDefinition&gt;
      &lt;/Grid.RowDefinitions&gt;
      &lt;GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Stretch"&gt;&lt;/GridSplitter&gt;
      &lt;GridSplitter  Grid.Row="1" Height="5" HorizontalAlignment="Stretch"&gt;&lt;/GridSplitter&gt;
  </code></pre>
