title: VB.NET DataGridView on select whole row
body: <p>I have a question for the DataGridView in vb.net (making a form).</p>
  
  <p>I have a button that is disabled. This button should only be enabled when a row in this list is marked/selected/highlighted. How can i write this? A doubleclick on the DataGridView gives me </p>
  
  <pre><code>Private Sub My_Grid_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles My_Grid.CellContentClick
  
  End Sub
  </code></pre>
  
  <p>This only works on some of the cells and does not do any thing if i click on the * to the left where i select and highlight this row.</p>
  
  <p>How do i do this?</p>
