title: How do you add items to a Canvas that is part of a UserControl?
body: <p>I have a usercontrol that contains 2 rows.  1st row has a label and 2nd row has a scrollviewer with a canvas:</p>
  
  <pre><code>&lt;Grid&gt;
      &lt;Grid.RowDefinitions&gt;
          &lt;RowDefinition Height="Auto"/&gt;
          &lt;RowDefinition /&gt;
      &lt;/Grid.RowDefinitions&gt;
      &lt;Label Grid.Row="0" Content="TITLE" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" Name="label1" VerticalAlignment="Top" FontSize="26" /&gt;
      &lt;ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled"&gt;
          &lt;Canvas Background="White" /&gt;
      &lt;/ScrollViewer&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>In my main window.xaml I'm trying to add this user control and then add items to it's canvas.</p>
  
  <pre><code>&lt;local:UserCanvas&gt;
      &lt;label Content="Test" /&gt;
  &lt;/local:UserCancas&gt;
  </code></pre>
  
  <p>There problem here is that when I had that label in there it just overrides the "TITLE" label in row 1 of the user control.  How do I add things so that they are placed on the cavas of the UserControl?</p>
