  <p>I have a DataGridView with a column which is filled with buttons. Now I want that with every click on the button the selected row in the DataGridView is copied and inserted directly behind the selected row. But: I only want to duplicate the value of 2 specific columns. And between this two specific columns one should be counted with numbers from 1 starting manually typed in to 2, 3, 4 and so on with every click on the duplicate button. The other columns should be empty. How can I realize this ?</p>
  
  <p>Many thanks in advance</p>
