Default4.aspx >Its Master page is MasterPage.master (This is parent page)
Default5.aspx (This is child page)
I have taken UpdatePanel in parent page to check whether it is working properly with UpdatePanel. Let us see codes of Default4.aspx:
HTML:
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true"
CodeFile="Default4.aspx.cs" Inherits="Default4" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
<script type="text/javascript">
function OpenPopup() {
window.open("Default5.aspx", "Popup", "scrollbars=no,resizable=no,width=500,height=250");
return false;
}
script>
asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div>
<table width="80%">
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text="Value from popup:">asp:Label>
td>
<td>
<asp:TextBox ID="txtOpenner" runat="server">asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Popup" OnClientClick="OpenPopup()" />
<asp:Label ID="Label2" runat="server" Text="">asp:Label>
td>
tr>
table>
div>
ContentTemplate>
asp:UpdatePanel>
div>
asp:Content>
Design preview:
When user click on Popup button popup window will be displayed and the textbox will show value sent from popup window.
Code behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Default4 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
int count = 0;
if (!IsPostBack)
{
Session["Count"] = 0;
}
if (IsPostBack)
{
Session["Count"] = count = int.Parse(Session["Count"].ToString())+1;
Label2.Text = "This page is postedback " + count.ToString() + " times";
}
}
}
Here I am counting how many time PostBack event is occurring in parent page and showing in Label2. I am doing this to clearly understand that parent page is refreshed clearly.
Now, Let us see codes of Default5.aspx:
HTML:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>
DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>title>
<script language="javascript" type="text/javascript">
function SendValue() {
var val = document.getElementById('<%=TextBox1.ClientID%>').value;
window.opener.document.getElementById("ctl00_ContentPlaceHolder1_txtOpenner").value = val;
window.close();
window.opener.document.forms(0).submit();
}
script>
head>
<body>
<form id="form1" runat="server">
<div>
<table width="100%">
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text="Give your name here:">asp:Label>
td>
<td>
<asp:TextBox ID="TextBox1" runat="server">asp:TextBox>
<asp:Button ID="btnSend" runat="server" Text="Send to opener" OnClientClick="SendValue()" />
td>
tr>
table>
div>
form>
body>
html>
using System;
public partial class Default5 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}

It would be very helpful if I get same functionality in ASP .NET MVC. I could not reproduce same effect in mvc application.
