title: WPF - XAML - Data Trigger without Binding / Value only trigger
body: <p>I have a grid of values in a DataGrid. In each cell I have one of 4 values, I want each value to have an associated colour.</p>
  
  <p>In the past all my data triggers have been of the format;</p>
  
  <pre><code>&lt;DataTrigger Binding="{Binding Status}" Value="R"&gt;
       &lt;Setter Property="xcdg:DataRow.Background" Value="Pink" /&gt;
  &lt;/DataTrigger&gt;
  </code></pre>
  
  <p>But I need something of the format;</p>
  
  <pre><code>&lt;DataTrigger Binding="{Binding *}" Value="R"&gt;
       &lt;Setter Property="xcdg:DataRow.Background" Value="Pink" /&gt;
  &lt;/DataTrigger&gt;
  </code></pre>
  
  <p>So that any cell's value will be checked. The reason I can't use explicit bindings is that the number of columns and their names is dynamic, I use extend CustomTypeDescriptor to expose the columns and rows to enter the grid.</p>
  
  <p>Thanks in advance!</p>
