How to Pass the Child window data to Textbox control within RadDock on parent page?

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Parent Page code:

01.<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="radwindow_parent_child_relation_Default" %>
02. 
03.<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
04. 
05.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
07.    <head runat="server">
08.        <title></title>
09.        <%--This script contains the commonly used functions for all dialogs. It is referenced by all dialog pages--%>
10.        <script src="JScript.js" type="text/javascript"></script>
11.    </head>
12.    <body>
13.        <form id="form1" runat="server">
14.            <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
15.                <Scripts>
16.                    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js">
17.                    </asp:ScriptReference>
18.                    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js">
19.                    </asp:ScriptReference>
20.                    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js">

23.            </telerik:RadScriptManager>
24.            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
25.            </telerik:RadAjaxManager>
26.            This is the main form. It will host all RadWindows. The JavaScript functions that are used are defined in a common
27.            JavaScript file so they can be reused easily. In a real application each page will define what the
28.            useDataFromChild() and generateDataForParent() functions will do, in this example they merely populate textboxes.

36.            <br />
37.            <script type="text/javascript">
38.                //this is the function that receives the data from the child popup and handles it on the current page
39.                function useDataFromChild(data)
40.                {
41.                    document.getElementById("Textbox1").value = data;
42.                }
43.            </script>
44.            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
45.                <ContentTemplate>
46.                    <telerik:RadDockLayout ID="RadDockLayout1" Runat="server">
47.                        <telerik:RadDockZone ID="RadDockZone1" Runat="server" Height="300px" Width="995px">
48.                            <telerik:RadDock ID="RadDock1" Runat="server" Height="142px" Width="933px">

Child page code :

01.<%@ Page Language="C#" AutoEventWireup="true" CodeFile="first.aspx.cs" Inherits="radwindow_parent_child_relation_first" %>

03.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

08.    </head>
09.    <body>
10.        <form id="form1" runat="server">
11.            This is the first dialog. It will open the second one and get data from it.

JScript.js code :

01.function returnDataToParentPopup(sender, args) {
02.    //get the data that was passed and return it to the parent reference. Note that you need to know that name of the function that will handle the data there

05.    if (sender.__parentBackReference && sender.__parentBackReference.useDataFromChild)
06.        sender.__parentBackReference.useDataFromChild(info);

08. 
09.function openChildDialog(url, wndName, title) {

25.        //you can even add arguments that will pass data from the parent to the child as shown here
27.        //in the On the Dialog Page section that shows how to access custom fields in the RadWindow object and use them.
28.        //of course, you can also use querystrings in the URL.
29.    }, 0);

31. 
32.function GetRadWindow() {

38.    return oWindow;
39.}
40. 
41.function sendDataToParent(dataForParent) {
