title: How to add a single combobox into a datagridview in random positions
body: <p>I want to add DatatGridViewComboBoxCell into dynamically determined cells onto the datagridview. </p>
  
  <p>So far all of the examples I have found either make the entire columns' cells into comboboxes or don't work. </p>
  
  <p>Here is the simplest example that I can come up with. I have tried databinding to sources which work to a point. The items exist in the combobox.items but on the datagridview the combobox is empty and you cannot select a value</p>
  
  <p><img src="https://i.stack.imgur.com/sFuUc.jpg" alt="ComboBox with no items being displayed"></p>
  
  <pre><code>DataGridArticles.Columns.Add("columna", "columna")
  Dim combo As New DataGridViewComboBoxCell
  
  combo.Items.Add("b")
  combo.Items.Add("ba")
  combo.Items.Add("ca")
  
  DataGridArticles.Rows.Add()
  DataGridArticles.Rows(0).Cells(0) = combo
  </code></pre>
  
  <p>Is it possible to add a combobox to a specific cell in a datagridview.</p>
