I have a datagrid that is bound to a list of objects (with only 1 object in 
the list).

If I edit the Name column of the object in the grid the value is not updated 
until I leave the cell.  I need to ensure that all changes are applied 
before the form closes so this is what I tried in the Form.Closing event

procedure TWinForm1.TWinForm1_Closing(sender: System.Object; e: 
System.ComponentModel.CancelEventArgs);
var
  Control: System.Windows.Forms.Control;
  BC: System.Windows.Forms.BindingManagerBase;
begin
  MessageBox.Show(ACountry.Name);
  for Control in Controls do
  begin
    BC := BindingContext[Control];
    BC.EndCurrentEdit;
  end;
  MessageBox.Show(ACountry.Name);

ACountry is a reference to the only object in the list, but both 
MessageBox.Show commands display the original value.  When I reopen the form 
I see the new value I typed has been accepted.

Can anyone tell me how to apply pending data changes immediately?
