Hi majestic,
I would suggest you to pass an id in query string using this code:
pnl1.AutoLoad.Params.Add(new Coolite.Ext.Web.Parameter("parentPanelId", "Panel2"));
Please see the following sample.
Example Parent Page
<%@ Page Language="C#" %>
<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>

<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Coolite.Ext.Web.Panel pnl1 = new Coolite.Ext.Web.Panel() { ID = "Panel1" };
pnl1.AutoLoad.Url = "A.aspx";
pnl1.AutoLoad.Mode = LoadMode.IFrame;
pnl1.AutoLoad.ShowMask = true;
pnl1.AutoLoad.Params.Add(new Coolite.Ext.Web.Parameter("parentPanelId", "Panel2"));
Coolite.Ext.Web.Panel pnl2 = new Coolite.Ext.Web.Panel() { ID = "Panel2" };
pnl2.AutoLoad.Url = "B.aspx";
pnl2.AutoLoad.Mode = LoadMode.IFrame;
pnl2.AutoLoad.ShowMask = true;
pnl2.AutoLoad.Params.Add(new Coolite.Ext.Web.Parameter("parentPanelId", "Panel1"));
Coolite.Ext.Web.Panel pnl3 = new Coolite.Ext.Web.Panel() { ID = "Panel3" };
pnl3.AutoLoad.Url = "A.aspx";
pnl3.AutoLoad.Mode = LoadMode.IFrame;
pnl3.AutoLoad.ShowMask = true;
pnl3.AutoLoad.Params.Add(new Coolite.Ext.Web.Parameter("parentPanelId", "Panel4"));
Coolite.Ext.Web.Panel pnl4 = new Coolite.Ext.Web.Panel() { ID = "Panel4" };
pnl4.AutoLoad.Url = "B.aspx";
pnl4.AutoLoad.Mode = LoadMode.IFrame;
pnl4.AutoLoad.ShowMask = true;
pnl4.AutoLoad.Params.Add(new Coolite.Ext.Web.Parameter("parentPanelId", "Panel3"));
Page.Controls.Add(pnl1);
Page.Controls.Add(pnl2);
Page.Controls.Add(pnl3);
Page.Controls.Add(pnl4);
}
}
