title: How to filter and show only selected items in datagridview?
body: <p>I have a datagridview and recently I got task to add a checkbox column (which I did) and a button (btnFilter) that will filter/show only selected rows so for example if I check only 4th, 5th and 6th row and click on 'btnFilter' the datagridview would show only rows 4,5 and 6.</p>
  
  <p>So, the problem is how to show only selected (checkbox) rows.</p>
  
  <p>Thank you for your time.</p>
