title: Grid component and sorting with custom sort listener
body: <p>I'm using grid component and default column sort behavior doesnt work for me correctly. I'm using a paged data so current grid data content is just a part of the entire data set. And default sorting feature sorts only data on screen and I need send the sort options to my database query. For this I added custom sort listener as on the example ...</p>
  
  <pre><code>e.g. grid.addSortListener(e -&gt; this.sortListener(e));
  </code></pre>
  
  <p>... so I can catch the sort order change user does on screen which works fine. But how can I disable the default sorting the Vaadin does in grid?</p>
