title: Set DataGridView arrow to the selected row
body: <p>How do I set the arrow to the selected row. I'm programatically selecting the rows based on the value of a combo box. Currently, only the row is highlighted and the arrow doesn't follow</p>
  
  <pre><code>foreach (DataGridViewRow row in dgv.Rows)
  {
      if ((int)row.Tag == ma.ID)//ma.ID is the selected combo box value
      {
          row.Selected = true;
      }
  }
  </code></pre>
