如何让用户控件中的子控件成为设计时的容器

Question

定义了一个winform中的用户控件UserControl1，该控件中有一个Panel，其中Panel声明为Public，
在UserControl1前定义了特性 [System.ComponentModel.Designer("System.Windows.Forms.Design.ParentControlDesigner,System.Design ")]，
此时UserControl1可以在设计时接受拖放进来的控件，而其中的Panel确不能，
现在我想让UserControl1中的Panel在设计时也可以将其他控件拖入到其中，如何作到这一点呢？
如果不明白我的意思，可以下载我上传的例程：http://g.zhubajie.com/urllink.php?id=5016607uhhkiqhqvbiwgr94
其中紫色部分是Panel。

我建议你去 Windows Forms Designer 论坛去讨论这个问题, 那里专门讨论这类问题.
