I know there is something I am missing on this
But am unable to figure out that
I have this master page:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="Mains.master.cs" Inherits="Sportsstop.Mains" %>
<!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>Sports Stop</title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
N there is this Child page which should merge with the above master page:
<%# Page Title="" Language="C#" MasterPageFile="~/Mains.Master" AutoEventWireup="true" CodeBehind="Home.aspx.cs" Inherits="Sportsstop.Home" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server" >
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
</asp:Content>
Your textbox should be in child page, inside ContentPlaceholder1. I think that the one in master page is ignored.
If you want to have TextBox in master page, it cannot be inside ContentPlaceholder
Think about placeholder as a place, where the content from child page gets injected

I am creating an asp website using a Master page. I have some links inside the content page. I want to surf them using updatepanel, leaving the master page content intact. How do I achieve that?

I have a page that uses a master page.
I disabled viewstate on the page (not the master page), and I didn't notice that the viewstate was reduced.
Curious if the masterpage setting will override it?
In my testing setting EnabledViewState = "False" will not reduce the page's view state while setting ViewStateMode="Disabled" will decrease the viewstate size

Hi:
I am new to asp.net,so I meet some problem about the master page.
I define a master page and set some css and js within it:
<%# Master Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML
1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server" >
<title>Master page title</title>
<script xx.js></script>
</head>
<body>
<form id="form1" runat="server">
<table>
<tr>
<td><asp:contentplaceholder id="Main" runat="server" /></td>
<td><asp:contentplaceholder id="Footer" runat="server" /></td>
</tr>
</table>
</form>
</body>
</html>
Then my child page:
<% # Page Language="C#" MasterPageFile="~/Master.master" Title="Content Page 1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server">
Main content.
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="Footer" Runat="Server" >
Footer content.
</asp:content>
When I start the child page,I found the xx.js is not included in this page,what is the problem?
<head>
<script type="text/javascript" src="xx.js"></script>
</head>
This "xx.js" should be in your appl
I have used Master Pages with ASP.Net for some time. I have been able to develop Master pages with header and footing content but never sucessful with side panels.
What this project needs is a Main Master page with header and footer contents. Then another master page that uses the first master page and has it's content of the left side of the remaining middle. The Detail will go to the right with the left master content about one third and the detail about two third.
A working example would be good if possible.
Thanks.

Possibly looking for nested master pages?

I have problem with my UserControl. It has inside the UpdatePanel, but it must be placed inside the tag to get worked (otherwise, the PostBack is not asynchronous)
The problem is, if I put that UserControl in e.g. Default.aspx page, the error appears
"A page can have only one server-side Form tag"
how to cope with that ?
[edit]
the UserControl.ascx code:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="PodmiotyZwolnioneCtrl.ascx.cs" Inherits="FormularzPodatkowy.PodmiotyZwolnioneCtrl" %>
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<link href="AjaxStyle.css" rel="stylesheet" type="text/css" />
<!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" >
<body>
<form id="form1" runat="server">
<div>
<asp:UpdatePanel ID="UpdatePanel1"
UpdateMode="Conditional"
runat="server">
<ContentTemplate>
<fieldset>
<legend>UpdatePanel content</legend>
<!-- Other content in the panel. -->
<%=DateTime.Now.ToString() %>
<br />
<asp:Button ID="Button1"
Text="Refresh Panel"
runat="server" />
</fieldset>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
the WebForm1.aspx code:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="FormularzPodatkowy.WebForm1" %>
<%# Register src="PodmiotyZwolnioneCtrl.ascx" tagname="PodmiotyZwolnioneCtrl" tagprefix="uc1" %>
<!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>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<uc1:PodmiotyZwolnioneCtrl ID="PodmiotyZwolnioneCtrl1" runat="server" />
</form>
</body>
</html>
Your code should be:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="PodmiotyZwolnioneCtrl.ascx.cs" Inherits="FormularzPodatkowy.PodmiotyZwolnioneCtrl" %>
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<link href="AjaxStyle.css" rel="stylesheet" type="text/css" />
<div>
<asp:UpdatePanel ID="UpdatePanel1"
UpdateMode="Conditional"
runat="server">
<ContentTemplate>
<fieldset>
<legend>UpdatePanel content</legend>
<!-- Other content in the panel. -->
<%=DateTime.Now.ToString() %>
<br />
<asp:Button ID="Button1"
Text="Refresh Panel"
runat="server" />
</fieldset>
</ContentTemplate>
</asp:UpdatePanel>
</div>
It looks like you converted a page to a control and forgot to remove the page-specific elements
Also, if your postbacks are not asynchronous, look at your web.config for:
<xhtmlConformance mode="Legacy"/>
and change it to:
<xhtmlConformance mode="Transitional"/>
I just spent three days at work finding that solution to UpdatePanel always posting back to the server.
You should check both the usercontrol and the page and make sure that you only have one <form id='form1' runat='server'> tag in your markup. Having more than one will give you the error that you're experiencing.
Good luck, and hope this helps some.
