title: Grid without background tapped event
body: <p>I have a simple grid.
  I want to handle Tapped event.</p>
  
  <pre><code>&lt;Grid Grid.Column="0" Grid.Row="0" Tapped="PlanszaItemTapped"  /&gt;
  </code></pre>
  
  <p>But when Grid doesn't have any background the event don't respond.</p>
  
  <p>This code working corectly but here is background.</p>
  
  <pre><code>&lt;Grid Grid.Column="0" Grid.Row="0" Tapped="PlanszaItemTapped" Background="#FFF7F4F4" Opacity="0" /&gt;
  </code></pre>
  
  <p>I don't need this background. Opacity is 0 but when I make animation background is visible.</p>
  
  <p>How to solve this issue?</p>
  
  <p>Generaly my goal is to create Grid with 10 colum and 10 row and OnClick any Item just add image.</p>
  
  <p>I use empty grids to respond the click event.</p>
  
  <p>There is any shortest way to do that?</p>
