How to get the RegisterName in WPF RRS feed

  • Question

  • I dynamic create the button using code like this:

    private void mainArea_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
                    targetPoint = e.GetPosition((IInputElement)sender);
                    Uid id = new Uid();
                    string uid = id.getUid();
                    _target = new Button()

                        content = "station",

                        Name = "station" + uid

                    Canvas.SetTop(_target, targetPoint.Y - 60);
                    Canvas.SetLeft(_target, targetPoint.X - 20);
                    mainArea.RegisterName(_target.Name, _target);

    And the "uid" is a random number, after this code i can create button on Canvas, but when i try to delete it or do something else , i found i cant get the name of the button.

    so anyone can tell me how to get the name or registername of this button or the button that i click?
