能夠拖動動態創建的面板

Question

我一直看到有關添加事件的文章能夠拖動面板。但是，我將如何通過動態創建的面板來實現這一點？

Panel pn = wch.GenerateWorkspaceControl(space.Name, space.Name, p); 
      PanelTest.Controls.Add(pn); 

     public Panel GenerateWorkspaceControl(string gbTitle, string gbName, Point gbPos) 
    { 
     Panel pnl = GeneratePanelContainer(gbPos, new Size(300, 200)); 
     pnl.Controls.Add(GenerateLabel(gbName,new Point(100,1),new Size(135,115))); 
     return pnl; 
    } 

private Panel GeneratePanelContainer(Point loc, Size size) 
    { 
     return new Panel() { BackColor = Color.Transparent, BorderStyle = BorderStyle.FixedSingle, Location = loc, Size = size }; 
    } 

是否在生成面板容器中添加事件處理程序？

總結我有一個面板是持有多個動態創建面板。我希望能夠在主面板內的動作創建的面板上移動。

任何想法？

這是一個讓你可以移動的控件。

只需註冊它：

MoveController.RegisterCtl(button1); 

現在，您可以移動控制..

完成後，你還可以註銷控制：

MoveController.UnRegisterCtl(button1); 

這裏是控制器類：

static class MoveController 
{ 
    static List<Control> Controls = new List<Control>(); 
    static Control curCtl = null; 
    static Point curStart = Point.Empty; 

    static public void RegisterCtl(Control ctl) 
    { 
     Controls.Add(ctl); 
     ctl.MouseDown += ctl_MouseDown; 
     ctl.MouseMove += ctl_MouseMove; 
     ctl.MouseUp += ctl_MouseUp; 
    } 

    static public void UnRegisterCtl(Control ctl) 
    { 
     if (Controls != null && Controls.Contains(ctl)) 
     { 
      Controls.Remove(ctl); 
      ctl.MouseDown -= ctl_MouseDown; 
      ctl.MouseMove -= ctl_MouseMove; 
      ctl.MouseUp -= ctl_MouseUp; 
     } 
    } 

    static void ctl_MouseDown(object sender, MouseEventArgs e) 
    { 
     curCtl = (Control)sender; 
     curStart = curCtl.Location; 
    } 

    static void ctl_MouseMove(object sender, MouseEventArgs e) 
    { 
     if (curCtl != null) 
     { 
      curCtl.Left += e.Location.X - curCtl.Width/2; 
      curCtl.Top += e.Location.Y - curCtl.Height/2; 
     } 
    } 

    static void ctl_MouseUp(object sender, MouseEventArgs e) 
    { 
     curCtl = null; 
    } 
}
