    Message.Text = "Update for the ContactID " + 
      ContactsListView.DataKeys[e.ItemIndex].Value.ToString()  + " canceled.";
  }
  else
  {
    Message.Text = "Insert operation canceled."; 
  }
}

Protected Sub ContactsListView_ItemCanceling(ByVal sender As Object, _
                                             ByVal e As ListViewCancelEventArgs)
  'Check the operation that raised the event
  If (e.CancelMode = ListViewCancelMode.CancelingEdit) Then
    ' The update operation was canceled. Display the 
    ' primary key of the item.
    Message.Text = "Update for the ContactID " & _
      ContactsListView.DataKeys(e.ItemIndex).Value.ToString() & " canceled."
  Else
    Message.Text = "Insert operation canceled."
  End If

End Sub
