title: How to clear/remove all rows for ag-grid
body: <p>I am trying to clear all current rows from my ag-grid. I tried to do this:</p>
  
  <pre><code>aggridOptions.api.setRowData([]);
  </code></pre>
  
  <p>but this adds me "No rows to show" dialog, then when I am updating the grid with new data the dialog is still appears. </p>
  
  <p>Is there correct way to clear the grid from data rows?</p>
