title: What event catches a change of value in a combobox in a DataGridViewCell?
body: <p>I want to handle the event when a value is changed in a  <code>ComboBox</code> in a <code>DataGridView</code> cell.</p>
  
  <p>There's the <code>CellValueChanged</code> event, but that one doesn't fire until I click somewhere else inside the <code>DataGridView</code>. </p>
  
  <p>A simple <code>ComboBox</code> <code>SelectedValueChanged</code> does fire immediately after a new value is selected. </p>
  
  <p>How can I add a listener to the combobox that's inside the cell?</p>
