title: DataGridView ComboBox Column: Change cell value after selection from dropdown is made?
body: <p>I have setup a ComboBoxColumn for my DataGridView and set its selectable values from an enumeration. It mostly works as I would like with the following exception.</p>
  
  <p>Whenever I click the dropdown arrow and then select one of the enum values, it remains in sort of a "intermediate" state where the CellValueChanged event isn't triggered. I need to focus on another cell or another control for the event to fire.</p>
  
  <p>I also have an event handler for the DataGridView's Leaving event which "validates" the contents by making sure that no cell is empty.</p>
  
  <p>So, if I create a row and fill all the cells and come to the (currently blank) ComboBox column, change it to a value, and then click a Run button; my error dialog pops up because the ComboBox selection wasn't "saved". </p>
  
  <p>How can I get around this? Is there a way that after I select a value from the drop down it automatically "sets" the value?</p>
  
  <p>Thanks!</p>
