I have written an aspx page in c# that uses a master page for a menu. On the child page, I have a scriptmanager control with an update panel. Everything works fine but the master page menu is displayed as a table instead of the menu format. Once the scriptmanager is removed from the child page, the menu is restored.The scriptmanger code is the first item under the content2 section.
<asp:Content ID = "Content2" ContentPlaceHolderID = "MainContent" runat="server">
<h1> Test page 1</h1>
<asp:ScriptManager ID="ScriptManager" runat="server" />
<asp:UpdatePanel ID="UpdatePanel" runat="server" />
<ContentTemplate>
Any help would be appreciated. Thanks!
In your master page at the top try this:
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager> // remove this script manager if you have included script manager in your other page.
// do other stuff.
</form>
</body>
For separate pages include your master file and try this:
<%# Page Title="" Language="C#" MasterPageFile="~/yourmasterfile.Master" AutoEventWireup="true"
CodeBehind="yourfile.aspx.cs" Inherits="yourproject.yourfile" culture="auto" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MasterPageContent" runat="server">
<asp:ScriptManager ID="ScriptManager2" runat="server">
</asp:ScriptManager> // remove this script manager if you have included script manager in master page
<asp:UpdatePanel ID="updatePannel1" runat="server">
<ContentTemplate>
// do your stuff here
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>

I have a master page Header.master which contains a logout button, due to this reason I have to include a form with run at server in my master form.
Again I am using a form in my page because I want to use controls and asp.net compiler says that you cant use controls with form tag with run at server.
Header.master
<form runat="server"><asp:ImageButton ID="btn_logout" runat="server" OnClick="btn_logout_Click" Height="22px" ImageUrl="~/img/logout.png" Width="43px" /></form>
My Page
<%# Page Title="" Language="C#" MasterPageFile="~/Header.Master" AutoEventWireup="true" CodeFile="student_registration.aspx.cs" Inherits="SCMS.student_registration" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<form id="frm_sr" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
</asp:UpdatePanel>
</form>
</asp:Content>
Remove Form tag from your page (My Page)
<form id="frm_sr" runat="server">
Form tag in master page is already enclosing all the code written in page itself
(<asp:Content ID=...>)
Ok, so i am doing a project with ASP.net, and using Visual Studio 2012. I created a new master page, in which i wish to make registration. I simply drop the "Create User Wizard" in the Login toolbox onto my page, and it goes completely off its hinges!!
<%# Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="Register.aspx.vb" Inherits="WebApplication1.Register1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="FeaturedContent" runat="server">
<asp:CreateUserWizard ID="CreateUserWizard1" runat="server" Height="10px" Width="10px">
<WizardSteps>
<asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
</asp:CreateUserWizardStep>
<asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server">
</asp:CompleteWizardStep>
</WizardSteps>
</asp:CreateUserWizard>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">
</asp:Content>
I cannot get anything inline like my previous pages.
Any suggestions?
It's not because wizard or something, it's about styles. You have a better browser (Chrome), just open your page in Chrome, right-click on desired element and choose "Inspect element".
Then take a magnifier:
Point this tool to desired element and check out styles on the right:
Try to enable/disable them right there, and you'll see result immediately.
I have a scenario like this (simplified for this question):
I have a master page:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="Ads.master.cs" Inherits="ActiveDigitalSignage.Ads" %>
<!DOCTYPE html>
<html>
<head>
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<div class="wrapper">
<form id="form1" runat="server">
<header>
</header>
<section>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</section>
</form>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<asp:ContentPlaceHolder ID="script" runat="server">
</asp:ContentPlaceHolder>
</body>
</html>
I have a default.aspx page:
<%# Page Title="" Language="C#" MasterPageFile="~/Ads.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<div><p>Test</p></div>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="script" runat="server">
</asp:Content>
The way its setup is, any header stuff can go in the "head" section. The main stuff goes in the "ContentPlaceHolder" and any javascript goes into the "script" place holder. Everything is working fine as is right now.
The issue I'm running into is I want to use a User Control (.ascx) in my Default.aspx page. However there is javascript in the user control. Because the jQuery is at the bottom of the page (in the "script" section), the javascript in the user user control is breaking. Is there a way to make the javascript in the user control render inside the "script" placeholder?
I know I can just copy and paste the code into a .js file and load the javascript in my master page. The problem with doing that is there are a bunch of ASP.NET tags (e.g. <%= %>) in the javascript that reference controls in the user controls, so copying and pasting this into a .js file would break this.
I'm thinking, off the top of my head, there might be a way in the global.asax page, during prerender, that can detect javascript in a user control and dynamically move it into the proper section?
I have 2 master pages that are nested.this is main master page code for example:
<%# Master Language="C#" AutoEventWireup="true" CodeFile="MasterPageMaster.master.cs" Inherits="MasterPageMaster" %>
<!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>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtMasterPageMaster" ClientIDMode="Static" runat="server"></asp:TextBox>
<div style="background-color:Aqua;height:40px;">
Some Text
</div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
and the nested master page:
<%# Master Language="C#" MasterPageFile="~/MasterPageMaster.master" AutoEventWireup="true"
CodeFile="MasterPageNested.master.cs" Inherits="MasterPageNested" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<asp:Panel runat="server" ID="panelMain" BackColor="lightyellow">
<h2>
Child master</h2>
<asp:Panel runat="server" ID="panel1" BackColor="lightblue">
<p>
This is child master content.</p>
<asp:ContentPlaceHolder ID="ChildContent1" runat="server" />
</asp:Panel>
<asp:Panel runat="server" ID="panel2" BackColor="pink">
<p>
This is child master content.</p>
<asp:ContentPlaceHolder ID="ChildContent2" runat="server" />
</asp:Panel>
<br />
</asp:Panel>
</asp:Content>
and I create a page based on this nested master page:
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPageNested.master" AutoEventWireup="true" CodeFile="PageMasterPageNested.aspx.cs" Inherits="PageMasterPageNested" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ChildContent1" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ChildContent2" Runat="Server">
<asp:Button ID="Button1" runat="server" Text="Button" Height="66px"
onclick="Button1_Click" Width="196px" />
</asp:Content>
I want in click of Button1 get text of main master page.
How I can do this?
In PageMasterPageNested.aspx:
TextBox txtBox = this.Master.Master.FindControl("txtMasterPageMaster") as TextBox;
Should work. Give it a try. Hope it helps.
This works in any case. especially if you dont know or care how many master pages you nested. Hope it helps :)
MasterPage tmp = this.Master;
while (tmp.Master != null)
{
tmp = tmp.Master;
}
var control = tmp.FindControl("form1");
I am building an ASP.NET application and would like to use a master page to display branding and navigation info and move through several content pages. However, every time I try to load new content the entire page flickers. Is there anyway to avoid this?
Master page:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="Interface.Site" %>
<%# Register TagPrefix="customControl" TagName="NavigationBar" Src="NavigationControl/NavigationControl.ascx" %>

<title>Registration</title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
<link href="Stylesheet.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="RegistrationMasterForm" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager" runat="server" EnablePartialRendering="true">
</asp:ScriptManager>
<%-- Contents of this div span the top of the page for branding --%>
<div id="BrandingBanner">
<asp:Image ID="Banner" runat="server"
ImageUrl="Images/BrandingBanner.png"/>
</div>
<%-- Navigation Bar, the contents of this div should remain unchanged --%>
<div id="NavigationBar">
<customControl:NavigationBar ID="navBar" runat="server"/>
</div>
<%-- Contains any forms or controls that may be uniquie to the page --%>
<div id="FormControls">
<div id="FormContent">
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</div>
</div>
</form>
</body>
</html>
Content:
<%# Page Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="Interface.WebForm2" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
Check me out! I am content for the master page!
<asp:Button ID="Button1" runat="server" Text="Next" onclick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
content code behind:
public partial class WebForm2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("WebForm3.aspx");
}
}
The control event triggers a post back to your page, which typically creates the "blanking" effect that you see. To mitigate this, you may want to consider using some sort of Ajax solution to cause a partial postback or async postback to prevent the "blanking".
However in the particular case of your button click, if all you are trying to do is bring the use to another page, you really should just use an <a href="WebForm3.aspx"> tag and avoid using Response.Redirect.
You are redirecting the page in your codebehind.
This causes the browser to change pages, and redraw the whole thing, at least IIRC. I haven't used updatepanels in ages.
Isnt this only possible if you're using frames? As far as I'm aware the master page and content pages bind together on the serverside and push down the the client as a whole.
Where what you want sounds like using an page for branding and navigation with an inline frame to serve up your convent. This would prevent the outer page from "flickering" on the client side.
Edit: Though it is not the new way to do things. You'd want to look at something using maybe an UpdatePannel or other AJAX style design.
You don't need to move the updatepanel, your redirect is causing the browser to load a new page.
