title: How do I make a DataGridView immediately commit edits?
body: <p>I have a master-detail layout with a section of popup menus (the Details) and a section with a DataGridView which holds the rows.</p>
  
  <p>The popup-menu state is updated when the selected row in the DataGridView changes and the state in the DGV's selected row should update when the popup-menu changes.</p>
  
  <p>All of this works <em>except</em> the row in the DataGridView doesn't immediately update when I change the value of the popup-menu. I have to select a different row in order to see my edits.</p>
  
  <p>I'm assuming this is because the edit hasn't been committed until the selection changes.</p>
  
  <p>My question is: How do I make the change to the popup become immediately reflected in the DataGridView?</p>
  
  <p>I have experimented with calling EndEdit() in the SelectionChangeCommitted handler for the popup-menu, but this has no effect. I'm interested in a technique that would allow me to create a DataGridView that would behave as if there were no Undo mechanism to begin with. Ideally the solution would be generic and transplantable to other projects.</p>
