I have a page with a gridview that displays results from a query and has paging and a search bar. It works fine when I load it by itself with not master page however when I add the master page to it all the controls disappear. below is the code with the master page and without
<%# Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeFile="Default3.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent"
Runat="Server">
<%# Import Namespace="GridView" %>
<div>
<div align="center" class="padded" >
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
Font-Size="Large" OnSelectedIndexChanged="Refresh_Click">
</asp:DropDownList>
<asp:Button ID="Refresh" runat="server" OnClick="Refresh_Click"
Text="Search" Visible="False" />
</div>
<div>
<cc1:HTMLGridView ID="HTMLGridView1" runat="server"
OnRowDataBound="OnRowDataBound2"/>
</div>
Here is the code that works with no master page
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs"
Inherits="_Default" %>
<%# Register assembly="GridView" namespace="GridView" tagprefix="cc1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<div align="center" class="padded" >
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
Font-Size="Large" OnSelectedIndexChanged="Refresh_Click">
</asp:DropDownList>
<asp:Button ID="Refresh" runat="server" OnClick="Refresh_Click"
Text="Search" Visible="False" />
</div>
<cc1:HTMLGridView ID="HTMLGridView1" runat="server"
OnRowDataBound="OnRowDataBound2" allowDeleting="False" allowEditing="False"
allowView="False"/>
</form>
</body>
</html>
I also added the reference to the web.config file but I have had no luck
<add tagPrefix="cc1" namespace="GridView" assembly="GridView" />
Where am I going wrong?
Try adding
<%# Import Namespace="GridView" %>
before
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent"
Runat="Server">

There is an UpdatePanel add inside UserControl, and this user control is added inside the MasterPage. When clicking on a button in that UpdatePanl. The whole page is refreshed. why?

I'm trying to move a page from an AJAX UpdatePanel to an Ajax Control Toolkit AccordianPane. When I run the app I get the following error :
DataBinding: 'AjaxControlToolkit.AccordionContentPanel' does not
contain a property with the name 'IsNdmaVisible'.
Here is a code snippet from the page I'm embedding in the AccordianPaneControl, with the property IsNdmaVisible in question, as referred to in the DataBinder.Eval method:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="ScenarioEditor.ascx.cs"

<script language="javascript" type="text/javascript">

</script>
</asp:Literal>
</ContentTemplate>
</asp:UpdatePanel>
Inasmuch embedding the above ScenarioEditor.ascx page, here with the original code snippet which works perfectly, followed by my new code, which obviously breaks (I'm including the assembly and code references only once for both snippets):
Reference and 'exteral' code registering:
<%# Page Title="" Language="C#" MasterPageFile="~/Shared/CareMaster.Master" AutoEventWireup="true" CodeBehind="EditScenario.aspx.cs" Inherits="Clients.Views.EditScenario" meta:resourcekey="PageResource1" %>
<%# Register Src="~/Clients/Controls/ScenarioEditor.ascx" TagName="ScenarioEditor" TagPrefix="clientControls" %>
<%# Register Src="~/SharedUserControls/CollapsibleContentPanel.ascx" TagName="CollapsibleContentPanel" TagPrefix="sharedControls" %>
<%# Register src="~/SharedUserControls/AjaxCalendar.ascx" tagname="AjaxCalendar" tagprefix="ajaxCalendar" %>
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
Working Code:
<asp:Content ID="MainContent" ContentPlaceHolderID="MainContent" runat="server">
<sharedControls:CollapsibleContentPanel ID="m_ScenarioEditorPanel" runat="server" style="margin-bottom: 1em">
<Title>

<clientControls:ScenarioEditor runat="server" ID="m_ScenarioEditor" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
</Content>
</sharedControls:CollapsibleContentPanel>
</asp:Content>
My code:
<ajaxToolkit:Accordion ID="Accordian1" runat="server">
<Panes>
<ajaxToolkit:AccordionPane ID="ScenarioDetails" runat="server">
<Header>Scenario Details</Header>
<Content>
<asp:UpdatePanel ID="ButtonsPanel" runat="server" BackColor="Yellow">

</div>
</ContentTemplate>
</asp:UpdatePanel>
</Content>
</ajaxToolkit:AccordionPane>
</Panes>
</ajaxToolkit:Accordion>
The code is the one below. I've tried several solution from other posts but none worked. This should be a very simple task tough. After clicking on the image, the calendar appears, the textbox is updated but when I get the .text property it still is unchanged.
Thanx for any help

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?
Master Page
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="TestJquery.Site1" %>
<!DOCTYPE html>

<% Response.Write(DateTime.Now); %>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
Default.aspx
<%# Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="TestJquery._default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<asp:HyperLink NavigateUrl="default2.aspx" runat="server">default.aspx</asp:HyperLink>

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" %>

<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">

<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.
