asp.net webcontrols : Master Pages and Cross-Page Form Information


David R. Longnecker
12/27/2005 1:08:22 AM
I'm slowly learning the new caveats of master pages and ASP.NET 2.0 and, =
so far, really enjoying it. A couple of questions to help kickstart my =
mind from the old ASP3 days. From what I've found, 2.0's cross-page =
posting allows me to set a PostBackURL and then =
Request.Form["objectName"] the information into the next page. Okay, =
that works up until I use Master Pages for my central header/footers. =
Using the Master Pages, it appears nothing is past to the Postback page; =
however, an error is not generated.

For example, on page 1 (default.aspx):
--
<%@ Page Language=3D"C#" MasterPageFile=3D"~/MasterPage.master" =
AutoEventWireup=3D"true" CodeFile=3D"Default.aspx.cs" =
Inherits=3D"_Default" Title=3D"Untitled Page" %>

<asp:Content ID=3D"Content1" =
ContentPlaceHolderID=3D"ContentPlaceHolder1" Runat=3D"Server">

Stuff with post back:
<asp:TextBox ID=3D"TextBox1" runat=3D"server"></asp:TextBox>
<asp:Button ID=3D"Button1" runat=3D"server" =
PostBackUrl=3D"~/Step2.aspx" Text=3D"Button" />

</asp:Content>
--

Simple enough... on the PostBack page, I want to just read what was =
typed in that textbox.
--
<%@ Page Language=3D"C#" EnableViewStateMac=3D"false" =
MasterPageFile=3D"~/MasterPage.master" AutoEventWireup=3D"true" =
CodeFile=3D"Step2.aspx.cs" Inherits=3D"Step2" Title=3D"Untitled Page" %>

<asp:Content ID=3D"Content1" =
ContentPlaceHolderID=3D"ContentPlaceHolder1" Runat=3D"Server">

In step 1, you typed: <% Response.Write(Request.Form["TextBox1"]; %>

</asp:Content>
--

The master page consists of the default code:
--
<%@ Master Language=3D"C#" AutoEventWireup=3D"true" =
CodeFile=3D"MasterPage.master.cs" Inherits=3D"MasterPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" =
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns=3D"http://www.w3.org/1999/xhtml" >
<head runat=3D"server">
<title>Untitled Page</title>
</head>
<body>
<form id=3D"form1" runat=3D"server">
<div>
<asp:contentplaceholder id=3D"ContentPlaceHolder1" runat=3D"server">
</asp:contentplaceholder>
</div>
</form>
</body>
</html>
--

Is there something about the master page that I'm missing?

Any good references/resources to using master pages would also be =
appreciated. :) I have no trouble fishing for it, however, today, not =
only were the fish gone, but the pond was dry.

Thanks in advance!

Hi David,

Welcome to MSDN newsgroup.
As for the querying TextBox values from Previous page when doing cross page
postback in asp.net 2.0, here are some of my understanding and suggestion:

1. the form values did exist in the Page.Request.Form collection. However,
since we're using Master page, the textboxes are cotained in the
ContentPlaceHolder which itself a child conttrol in the page's control
structure, so to avoid naming clash, the asp.net page will generate a
unique ID for all the child controsl in it (mangling their ID).... So we
can not use those Textboxs' original ID to query value from request.Form
collection. But we can printout them through the following code (to confirm
that they did exists..):
=====================
protected void Page_Load(object sender, EventArgs e)
{
if (PreviousPage != null && PreviousPage.IsCrossPagePostBack)
{

foreach (string key in Request.Form.Keys)
{
Response.Write("<br>" + key + ": " +Request.Form[key]);
}

}
}
====================


2. Actually the recommended means to retrieve Control property values in
Previous for cross page postback is defining some public Properties in the
Previous page's page class code which expose those certain controls'
property.... Then, we can use those Properties in the Target page's
code.... e.g:

Suppose we have two pages:


The first page is as below:
==========step1.aspx===========
<%@ Page Language="C#" MasterPageFile="~/CrossPost/TM.master"
AutoEventWireup="true" CodeFile="Step1.aspx.cs" Inherits="CrossPost_Step1"
Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1"
Runat="Server">
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />
<asp:Button ID="btnCrossPost" runat="server"
PostBackUrl="~/CrossPost/Step2.aspx"
Text="Cross Post Back" />
</asp:Content>

And the codebehind is
==========step1.aspx.cs============
public partial class CrossPost_Step1 : System.Web.UI.Page
{
public string TextBox1Value
{
get
{
return TextBox1.Text;
}
}

public string TextBox2Value
{
get
{
return TextBox2.Text;
}
}


}



the target page (step2.aspx)'s aspx and codebehind:

=======step2.aspx============
<%@ Page Language="C#" MasterPageFile="~/CrossPost/TM.master"
AutoEventWireup="true" CodeFile="Step2.aspx.cs" Inherits="CrossPost_Step2"
Title="Untitled Page" %>
<%@ Reference Page="~/CrossPost/Step1.aspx" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1"
Runat="Server">
</asp:Content>



=====step2.aspx.cs==========

protected void Page_Load(object sender, EventArgs e)
{
if (PreviousPage != null && PreviousPage.IsCrossPagePostBack)
{

CrossPost_Step1 page1 = PreviousPage as CrossPost_Step1;

if (page1 != null)
{
Response.Write("<br>" + page1.TextBox1Value);
Response.Write("<br>" + page1.TextBox2Value);
}

}
}

============================


Note that the below directive in the step2.aspx is very important:

<%@ Reference Page="~/CrossPost/Step1.aspx" %>


this indicate that we'll reference that page (~/CrossPost/Step1.aspx)'s
class or code in this page so that the asp.net runtime will compile them
into same assembly so as to make them visible to each other...............

From what I can tell it worked like a charm... battling a IDE issue right
now (VS 2005 locking up with "Visual Studio is Busy" that I'm working to
resolve right now); however, it seemed to work exactly like I needed.
Thanks for your help!

Okay, I do have a theory question. What happens if/when I need to move
through the web site non-linear? The Reference Page means that it has to go
sequentially; however, I can foresee times where I'd want to allow the user
to go back and forth along the steps. Can you still make the variables
public and call them or would I need to place the information into a session
each page hop, then do a verification on the final "step"?

Thanks!

Thanks for your response David,

If you want to record such a navigation path so that the user can move
forward or backward through that path... I think using SessionState will be
prefered. CrossPage posting only make sense when the original using http
post to submit to the second page, there're also many other navigation
scenarios like Response.Redirect, clientscript redirect.... So I think
use SessionState should be the better approach to record such info(when a
certain new page is navigated....)..

Hope helps. Thanks,

| Thanks for your response David,
|
| If you want to record such a navigation path so that the user can move
| forward or backward through that path... I think using SessionState will
be
| prefered. CrossPage posting only make sense when the original using http
| post to submit to the second page, there're also many other navigation
| scenarios like Response.Redirect, clientscript redirect.... So I think
| use SessionState should be the better approach to record such info(when a
| certain new page is navigated....)..
|
| Hope helps. Thanks,

| | Okay, I do have a theory question. What happens if/when I need to move

to

| user
| | to go back and forth along the steps. Can you still make the variables

| session
| | each page hop, then do a verification on the final "step"?

Your response is great; I'm slowly working to change some of the current
page into a session state and will post if any problems arise. Thanks for
your help!
