title: Datagridview SelectionChanged event based on row selection
body: <p>I have a DataGridView on a TabPage. When the user clicks on a row, a second DGV appears. Each row is associated with its own DGV filled with data. What I want is for when the user goes from one row to another, the DataGridView changes too. So far I've tried the SelectionChanged event but I don't want the DGV to reload in the event that the user clicks on a separate cell in the same row. Any help would greatly be appreciated.</p>
  
  <pre><code>void dgv1_CellClick(object sender, DataGridViewCellEventArgs e)           
  {    
      int rowIndex = dgv1.Rows[e.RowIndex].Index;
  
      if (dgv1 == null)
          return;
      if (dgv1.Rows[e.RowIndex].Cells[rowIndex].Selected == true);
      {
          dgv2.Size = new Size(dgv2.Width + 800, dgv2.Height);
          dgv2.Location = new Point(0, 500);   
  
          tp.Controls.Add(dgv2);
  
          Console.WriteLine("Row clicked");
      }
  }
  </code></pre>
