title: XAML DataTrigger for just one grid in Style for multiple grids
body: <p>I have 2 grids which use the same Style. I had to add a DataTrigger where a row is displayed red if a property (from the DataRow) is true.
  Unfortunately I only need the DataTrigger on one of those grids. The other grid doesn't even own the property.
  I found 2 solutions which feel both dirty:</p>
  
  <ul>
  <li>Add the property to the grid where its not used/displayed but to prevent the error</li>
  <li>Add another style which is a copy of the first one but has the DataTrigger on top</li>
  </ul>
  
  <p>Is there a way to apply this DataTrigger to just one grid when two grids are effected by the style which contains the DataTrigger?</p>
  
  <p>Thanks in advance!</p>
