title: Using Xceed PropertyGrid
body: <p>I am a beginner at C#/WPF and am trying to use the Xceed PropertyGrid. On their site they show an example:</p>
  
  <pre><code> &lt;xctk:PropertyGrid x:Name="_propertyGrid" Width="450" Margin="10"
                                   AutoGenerateProperties="False"&gt;
              &lt;!-- Only the following properties will be displayed in the PropertyGrid --&gt;
              &lt;xctk:PropertyGrid.PropertyDefinitions&gt;
                  &lt;xctk:PropertyDefinition Name="FirstName" /&gt;
                  &lt;xctk:PropertyDefinition Name="FavoriteColor" /&gt;
                  &lt;xctk:PropertyDefinition Name="PetNames" /&gt;
              &lt;/xctk:PropertyGrid.PropertyDefinitions&gt;
          &lt;/xctk:PropertyGrid&gt;
  </code></pre>
  
  <p>Which I have plugged in to my xaml. I see the PropertyGrid View however I do not see any of the property definitions.  I feel like I must be missing something basic? Am I supposed to add anything to the code-behind?</p>
