title: Datagridview ComboBoxCell set default value?
body: <p>I have a datagridview with lots of data, and when I add a new line, the first column's last row creates a new ComboBoxCell which contain four items. But I can't set the default value ("DropDown") for the combobox. Every time I must manually select "DropDown". What is the solution?</p>
  
  <pre><code> DataGridViewComboBoxCell dgvCell = new DataGridViewComboBoxCell();
   dgv[1, dgv.Rows.Count - 1] = dgvCell;
  
   string[] controltype = {"DropDown", "CheckBoxList", "ListControl", "Tree" };
   dgvCell.DataSource = controltype;
  </code></pre>
