在父页面Parent.aspx点击弹出第二个页面，将会弹出Child.aspx子页面，在子页面中输入需要传入到Parent.aspx的值点击确认，则可以把Child.aspx子页面输入的值传到Parent.aspx上的控件上。
Parent.aspx的HTML为：

<%@ Page language="c#" Codebehind="Parent.aspx.cs" AutoEventWireup="false" Inherits="TestToParent.WebForm1" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<HTML>

<HEAD>

<title>WebForm1</title>

// ------------------弹出window.open窗口--------------------

function openwin(fileName,type,window_width,window_height,property)

{

var top = (window.screen.availHeight-window_height)/2;

var left = (window.screen.availWidth-window_width)/2;

var newwindow;

if (window_width=="" && window_height=="")

{

if (type=="0")

{

newwindow=window.open(fileName,"","left="+left+",top="+top+","+property);

}

else

{

newwindow=window.open(fileName,"","left=0,top=0,"+property);

}

else

{

if (type=="0")

{

newwindow=window.open(fileName,"","left=0,top=0,height="+window_height+",width="+window_width+","+property);

}

else

{

newwindow=window.open(fileName,"","left="+left+",top="+top+",height="+window_height+",width="+window_width+","+property);

}

return newwindow;

}

function openwinsimp(fileName,window_width,window_height)

{

//alert(fileName);

var newwindow=openwin(fileName,'1',window_width,window_height,'resizable=no,scrollbars=auto,status=yes,toolbar=no,menubar=no,location=no');

newwindow.focus();

return newwindow;

}

</script>

function getid()

{

var id = new String(window.location.href);

//alert(id);

if( id.indexOf("id=", 1) ==-1 )

{

id=-1;

}

else

{

id = parseInt( id.substr( id.indexOf("id=", 1) + 3 ) );

}

// alert(id);

return id;

}

</script>

</HEAD>

<asp:TextBox id="txt_Child" style="Z-INDEX: 101; LEFT: 232px; POSITION: absolute; TOP: 80px"

runat="server"></asp:TextBox>

<asp:Label id="Label1" style="Z-INDEX: 102; LEFT: 96px; POSITION: absolute; TOP: 32px" runat="server">第一个页面</asp:Label>
