title: Check if dataGridView is empty
body: <p>I am in need of a simple way for checking if my datagridview is/isn't empty.<br>
  <strong>The Rows.Count does not satisfy me</strong>, because my program starts with 2 empty rows,<br>
   and in the future the datagridview could be populated and then the count<br>
   does not affect anything<br>
  (If the users deletes a section but there are more than 2 rows present).</p>
  
  <p>Is there anyway of checking this?</p>
