title: BaseOn not working properly
body: <p>I'm trying to inherit the Mahapp style of Datagrid, I've created a style for the rows of the Datagrid like this:</p>
  
  <pre><code>&lt;UserControl.Resources&gt;       
      &lt;Style x:Key="DataGridRow"&gt;
          &lt;Style.Resources&gt;
              &lt;Style TargetType="DataGridRow" BasedOn="{StaticResource MetroDataGridRow}"&gt;
                  &lt;Style.Triggers&gt;
                      &lt;DataTrigger Binding="{Binding Selected}" Value="True"&gt;
                          &lt;Setter Property="Background" Value="LightGray"&gt;&lt;/Setter&gt;
                      &lt;/DataTrigger&gt;
                  &lt;/Style.Triggers&gt;
              &lt;/Style&gt;
          &lt;/Style.Resources&gt;
      &lt;/Style&gt;
  &lt;/UserControl.Resources&gt;
  </code></pre>
  
  <p>Unfortunately when I apply this style on the Datagrid I get the default style of wpf and not mahapp, what am I doing wrong? thanks</p>
  
  <pre><code> &lt;DataGrid AutoGenerateColumns="False" CanUserAddRows="false" Style="{StaticResource DataGridRow}"&gt;
  </code></pre>
