title: What does RowDefinition Height="10*" mean in a XAML Grid?
body: <p>I use Height="*" a bit to mean that the height of the last row should fill to the bottom of the grid.</p>
  
  <p>But what does "10*" mean?</p>
  
  <pre><code>&lt;Grid Name="mainGrid"&gt;
      &lt;Grid.RowDefinitions&gt;
          &lt;RowDefinition Height="100" /&gt;
          &lt;RowDefinition Height="40" /&gt;
          &lt;RowDefinition Height="10*" /&gt;
      &lt;/Grid.RowDefinitions&gt;
      &lt;Grid.ColumnDefinitions&gt;
          &lt;ColumnDefinition Width="200"  /&gt;
          &lt;ColumnDefinition Width="*" /&gt;
      &lt;/Grid.ColumnDefinitions&gt;
  &lt;/Grid&gt;
  </code></pre>
