title: Multiple selection in datagridview
body: <p>I work on a new project that need a multiple row selection/deselection by the user in a datagridview with only a tap on a touch screen.</p>
  <p>The form should look like this:</p>
  <p><a href="https://i.stack.imgur.com/T6LyT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/T6LyT.png" alt="Form Screenshot" /></a></p>
  
  <p>For exemple, if the user want to delete row 2 and 5, he only need to tap once on each line to select/deselect them.  After the selection is done, he tap on &quot;Delete Row&quot; button.</p>
  <p>I've already try to play with the CellClick event without success!!</p>
  <p>Can someone have a clue how can I handle this problem?</p>
