title: gridEX row selection change on buttonclick not visible
body: <p>I'm having a gridEX component and up/down buttons for changing the selected row accordingly. If I select a certain row from the table, the up button should select the row above the previously selected row.</p>
  
  <pre><code>private void btnUp_Click(object sender, EventArgs e)
      {
          //TODO
          int rowIndex = gridEX.Row;
  
          if (rowIndex &gt; 0)
          {
              GridEXRow newSelectedRow = gridEX.GetRow(rowIndex-1);
              gridEX.SelectedItems.Clear();
              gridEX.MoveTo(newSelectedRow);   
          }
      }
  </code></pre>
  
  <p>The code above selects the right row, but the selection is not visible, like it would be if I click on the row.
  What could be the problem?</p>
