MouseClick on TableLayoutPanel？

Question

我有一个TableLayoutPanel，其中添加了一些控件，如Label和PictureBox。现在，我正在尝试在这个MouseClick中添加一个TableLayoutPanel处理程序。如果我确实删除了这些控件标签并使用PictureBox，就会正确地触发Handler，但是对于控件，我尝试将这些控件发送回原来的位置，例如：Label.SendToBack()，但它也不起作用。我认为问题在于控件标签和PictureBox，因为没有它们可以正常工作。

我怎么能解决这个问题？

void initComponents(){
            IList<Mesa> lista = mDAO.findAll();
            if (lista.Count > 0){
                foreach (Mesa mesa in lista){
                    customPanel = new TableLayoutPanel();
                    customPanel.MouseClick += cms_MouseClick; //mouseclick of customPanel
                    customPanel.BorderStyle = BorderStyle.None;
                    customPanel.BackColor = Color.FromArgb(255, 255, 128);
                    customPanel.Size = new Size(100, 100);
                    customPanel.Name = Convert.ToString(mesa.id);

                    //label mesa
                    numMesa = new Label();
                    numMesa.Font = new Font(numMesa.Font.Name, 12, FontStyle.Bold);
                    numMesa.Text = Convert.ToString(mesa.id);
                    numMesa.SendToBack();

                    //picturebox
                    picture = new PictureBox();
                    picture.Anchor = (AnchorStyles.Top | AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right);
                    picture.Image = IguanaBar.Properties.Resources.mesabar;
                    picture.SizeMode = PictureBoxSizeMode.StretchImage;
                    picture.SendToBack();

                    //label aviso
                    aviso = new Label();
                    aviso.Anchor = (AnchorStyles.Right);
                    aviso.Font = new Font(aviso.Font.Name, 6, FontStyle.Bold);
                    aviso.Text = "LIVRE";
                    aviso.ForeColor = Color.Green;
                    aviso.TextAlign = ContentAlignment.MiddleCenter;
                    picture.SendToBack();

                    //add components
                    customPanel.Controls.Add(numMesa);
                    customPanel.Controls.Add(picture);
                    customPanel.Controls.Add(aviso);

                    //add panel a panel principal                    
                    panelMesas.Controls.Add(customPanel);
                }                
            }            

            //popup menu
            cms = new ContextMenuStrip();
            cms.Items.Add("Vender");
            cms.Items.Add("Finalizar");
            cms.Items.Add("Trocar");
        }

Answer 1

你可以改变

 numMesa.SendToBack();
 picture.SendToBack();

至

  numMesa.MouseClick += cms_MouseClick; //mouseclick of customPanel
  picture.MouseClick += cms_MouseClick; //mouseclick of customPanel
