The ListViewCancelMode enumeration is used to represent the type of operation that the user was performing when the Cancel button was clicked in a ListView item. (A Cancel button is a button whose CommandName property set to "Cancel".)

The following example shows how to use the ListViewCancelMode enumeration to check which operation is being canceled in a ListView item.

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
