title: How to filter selected Rows in AG grid and keep it as selected?
body: <p>I want to filter my AG grid rows based on checkbox selection and I want to keep them as selected.</p>
  <p>I know using below method I can filter selected rows but after filtering the rows are losing its selected state.</p>
  <pre><code>gridOptions.api.setRowData(gridOptions.api.getSelectedRows())
  </code></pre>
  <p>I can run <code>gridoptions.api.selectAll()</code> but I have to avoid it as I don't want AG grid selection change event to be triggered.</p>
  <p>Any Idea how can I achieve it?</p>
