I have a a page that belongs to a master page. Inside the page I have 3 controls that are inside of UpdatePanels. On a postback, those three controls lose their style sheets.
I have tried...
Setting the script manager's EnablePartialRendering property to true
Putting the style sheets at the top of the ASPX file
Putting the style sheets in the header tag of the master file
Putting a ContentPlaceHolderID on the main page and master page, with the style sheets on the ContentPlaceHolderID on the page
No matter what I do the controls lose their style sheet on postback. Any idea why?
In the head tag on the master page:
<asp:ContentPlaceHolder ID="HeaderContentPlaceHolder" runat="server"/>
On the page file, at the top:
<asp:Content ID="Content2" ContentPlaceHolderID="HeaderContentPlaceHolder" Runat="Server">
<link rel="stylesheet" href="../../Content/bootstrap-multiselect.css" />
<script type="text/javascript" src="../../Scripts/bootstrap-multiselect.js"></script>
</asp:Content>

I have got a master page with three content holders. Say; Header, Menu and Content.
I can use Iframes or regular frames, but is there a way to specify the three content holders as follows and redirect them to three different web forms?
The reason I ask this, is because I do not want to specify my menu over and over again for every single web form.
<asp:Content ID="Content1" ContentPlaceHolderID="Header" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="Menu" runat="server">
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="Content" runat="server">
</asp:Content>
You've missed the point of a master page. A master page should contain the markup/code that is common to the content pages or nested master pages that reference it. Put the menu code into the master page.
<!-- Menu code here -->
<ul class="menu">
<li>Home"</li>
<li>Contact"</li>
</ul>
!-- End menu code -->
<asp:ContentPlaceHolder ID="MenuPlaceHolder" runat="server">
<!-- On the content page, your page specific menu code would go in the <asp:Content> that references this -->
</asp:ContentPlaceHolder >
As an alternative to (or in conjunction with) master pages, you can use user controls. You place your menu code in the user control and embed it in master pages or content pages. But if you always want it in the same place, then a master page makes more sense because of the Don't Repeat Yourself principle.
There is absolutely no reason to use an iframe for this.
I have a masterpage and a webform. In my masterpage,I have treeview (for menu) and I put form tag in that with runat=server.
In my webform, I have registration form created and i put form tag for that with runat= server.
When I buid it, its shows error as One form is allowed in a page.
How to use multiple runat=server forms for different processes in masterpage and inherited webform.
<form id="treeview" runat="server">
// treeview code
</form>
You really dont need to add a form tag in the child form i.e. Registration form. During run time both master and Child will be merged together and will render as a single form.
Here goes your Master page:
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="MainContent" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
And here is your Content Or Child page:
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<!-- Any other controls -->
</asp:Content>

Master form do you mean master page?
Then no, you cannot have 2 forms running on the same WebForm
I have created a master page, which has the following css:
body { background-image:url(images/back.jpg); }
This image is the one I want to appear on my Index page. When a user clicks the "Next" button, I want to change the image to be a different one.
How can I do this?
you can over-ride the css of master page with new css on other page. The back-ground image for body loaded first will come on back ground the second one will be ignored.
You can use masterpage placeholders to the header
<head>
<link rel="stylesheet" type="text/css" href="master.css">
<asp:contentplaceholder id="Header" runat="server" />
</head>
Then add this code to your NewPage.aspx
<% # Page Language="VB" MasterPageFile="~/Master.master" Title="Content Page 1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Header" Runat="Server">
<link rel="stylesheet" type="text/css" href="newpage.css" />
</asp:Content>
Now you can override the "CSS body" inside newpage.css
If you are loading Another page without page refresh then this will work:
HTML:
<button class="next">Next</button>
jQuery:
$(function() {
$('.next').click(function() {
$(body).css('background-image', 'url(images/back2.jpg)');
});
}):
And if navigating from one page to 2nd gets the page refreshed then
you can simply specify internal css.
I have a master page which containing few CSS links and java scripts.
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<script src="Scripts/slides.min.jquery.js" type="text/javascript"></script>
<asp:ContentPlaceHolder id="head" runat="server">
<script language="javascript" type="text/javascript">
$(document).ready(
function () {
$("#pikame").PikaChoose();
});
</script>
</asp:ContentPlaceHolder>

I want to use this JavaScript and css style files ,in child ASP form page which has inherited from above master page.
<%# Page Title="" Language="C#" asterPageFile="~/MasterPage.master"AutoEventWireup="true" CodeFile="LeadInformation.aspx.cs" Inherits="LeadInformation" %>
<%# MasterType TypeName="MasterPage" %>
Seems this way not working. Please anyone help me to use masterpage CSS and JavaScript in child-page to me. Tx in advanced.
Put your script outside the ContentPlaceHolder tag. Just put it in the head section normally.
The ContentPlaceHolder tag should be empty in the Master Page - its contents will be replaced by the asp:Content tags in the Pages.
You can check if it's being rendered properly by browsing to the page and right-click -> View Source.
<asp:ContentPlaceHolder id="head" runat="server">
is used to provide script,css that are specific to only that child page
so if you want the scripts/css to be applied to the child pages just place it normally in the master page head section and outside head ContentPlaceHolder in master page..
Hope this helps....
First, child pages are not inherited from master pages. It's the same page.
Second, you don't need MasterType directive to access javascript.
So just consider masterpage and child page to be one as it will be one page when it renders to Browser and javascript runs on browser. So you can place your javascript/CSS anywhere in the head section of master page and access it from any of the child page in a same manner as they are on the same page.
I have created a custom master page and have the follwoing code on the page:
<asp:ContentPlaceHolder id="PlaceHolderSearchArea" runat="server">
<SPSWC:SearchBoxEx id="SearchBox"
RegisterStyles="false"
TextBeforeDropDown=""
TextBeforeTextBox="Search"
TextBoxWidth="120"
GoImageUrl="/_layouts/images/gosearch.png"
GoImageUrlRTL="/_layouts/images/gosearch.png"
UseSiteDefaults="true"
DropDownMode = "HideScopeDD"
SuppressWebPartChrome="true"
runat="server"
WebPart="true"
__WebPartId="{07E563F9-A259-4829-920F-03829BBC14D1}"
GoImageActiveUrl="/_layouts/images/gosearch.png"
GoImageActiveUrlRTL="/_layouts/images/gosearch.png"/>
</asp:ContentPlaceHolder>
On one site this code works correctly and on another it does not work and the default search box apears. I can not work out why this is happening. Any ideas?
The content in the contentplaceholder "PlaceHolderSearchArea" can be overwritten by a <asp:Content /> element in a page layout. So check the page layouts you are using for the existance of an <asp:Content/> with the placeholder id "PlaceHolderSearchArea".
