推荐答案

System.Web.UI.WebControls.Panel myPanel = null;
            Control ctl = this.Parent;
            while (true)
            {
                myPanel = (System.Web.UI.WebControls.Panel)ctl.FindControl("myPanel");
                if (myPanel == null)
                {
                    if (ctl.Parent == null)
                    {
                        return;
                    }
                    ctl = ctl.Parent;
                    continue;
                }
                break;
            }

为面板创建属性，然后公开这些属性.之后，您将可以从UC访问.

例如.

Create property for panel and then expose those. After that you will be able to access from UC.

for ex.

public string MyPanel
    {
      get { return panelName; }
    }

或者您可以使用以下技术.

Or you can use below technique.

protected void UCMethod()
{    
   Page myParent = this.ParentPageName;    
   Panel panel = myParent.PanelId; //Here you can access any property of parent page
}
