Master Pages in MOSS 2007

'MasterPages' feature in sharepoint 2007 makes the entire customization job easy.In 2003 we used to face lot of issues to get the same look and feel and the standard behaviour for overall site. In 2007, customizing the look and feel for the entire site can be done in a simple way by using 'MasterPage' feature.

Combine, minify and compress JavaScript files to load ASP.NET pages faster

Websites are getting more interactive these days and most of this interactivity comes from JavaScript. People are using different JavaScript libraries and frameworks to make their websites more interactive and user friendly.

Re-positioning an HTML container with javascript onresize with a Master page.


I have an HTML <div> container that I float to the right of a gridview.  When the browser window is maximized, it looks fine.  When minimized, the gridview positions below the floating container and most of the data is pushed off the bottom of the browser - you have to scroll down to see it.

If I position the floating container above the gridview it looks fine in a minimized window, but looks real bad when maximized.

What I want to do is use a javascript: onresize event to re-position the floating container up or down depending on the window.inner.width AND do it with a Master/Content page structure AND do it for only the one page where needed.

I can capture the onresize event and display the window dimensions but haven't figured-out how to do it with a Content page that still uses the Master page.  I think I'm having a very "thick" week...

Master Pages: Master Your Site Design with Visual Inheritance and Page Templates


Master pages in ASP.NET 2.0 solve a problem many Web developers have been solving on their own with a variety of techniques for years - providing a single master template for an entire site. This article covers the details of master pages, discussing their usage and implementation and how they are a natural evolution of custom techniques developers are using today.

Ajax and master pages


I have a site that uses master pages.  Some of my pages use ajax, so they have the scriptmanager on them.  I now have to add some ajax to one of the master pages.  When I try to display a page that already has a script manager on it, I get an error that I can only have one script manager.  Is there a way to deal with this other then searching for every page that uses the master page and ajax and removing the scriptmanager tag? 

I'm hoping to start using Ajax more and more, so I'm really more concerned with best practices then I am about having to find and remove tags.  What is the right way to use Ajax on master pages and some, but not all content pages?

Why do the aks master pages not get applied if the feature is not activated on the top site collecti


I installed AKS 2.0 and activated AKS feature. The problem I found was the aks master pages do not get applied if the feature is not activated on the top site collection. why is so?

example: If i activate the feature on http://<servername>/sites/<sitename> and apply the master page, I dont see any changes.

              But if i activate the same aks feature on http://<servername/ then everything started working on all sites.

              The reason i found is the CSS reference in the aks master pages.

              It reference should be given as follows:

                 for http://<servername>/sites/<sitename> ->  <link rel="stylesheet" type="text/css" href="../../Style%20Library/AKS/Aks_Band_Blueband.css"/>

                 for http://<servername>/ -><link rel="stylesheet" type="text/css" href="/Style%20Library/AKS/Aks_Band_Blueband.css"/>

So my question is, am i missing anything? am i supposed to activate the AKS feature on top level site collection at any cost? if yes, why is so? 

And after applying aks master pages, i see differnece in font sizes. Why the font size is getting changed?


Sharepoint 2007 - Wiki site - New Pages Not Inheriting Custom Master Page


I am working on a SP site (MOSS not WSS) which is heavily customised away from the OOTB layout. I need to create a Wiki site, which was going well - I've created a master page which displays the miniconsole (this was not visible with our customised layout), and made it the default master page for the site. This has been applied to the two standard pages that come with the Wiki site, however when a new page is created, it seems to inherit the default.master, rather than my custom master page - thus not showing the miniconsole.

When I have created a new page, I am able to use SharePoint Designer to attach my custom master page to it, which works perfectly, however this will not be a viable option going forward as end-users create their new wiki pages.

How can I get the new pages to inherit my master page when they are created?


Inherit from multiple master pages


How does one inherit from multiple master pages?


I.e.  I have a base master page that contains several ContentPlaceHolders.









I want to have separate master page files (one for each ContentPlaceHolder) so that I have 4 separate files: 3 ContentPlaceHolders (each adding specific content) and 1 base master page.

The ASPX files will then inherit from the base master page.



Programmatically Hide Master Pages from Site Master Page Settings page?



I know there is a field you can check when you edit the properties of a Master Page in the Master Page Gallery to set a Master Page to hidden but ... can anyone think of a way to programmatically hide specific Master Pages from the Site Master Page Settings page?

Maybe this should be two questions:

  1. How do I programmatically access a Master Page in a Master Page Gallery?
  2. Is there a property that can be set that will hide the page from the Site Master Page Settings page?

collapsiblepanelextender, master page and javascript

does anyone have any working code that uses javascript to open and close a cpe when the CPE is in a masterpage?  It seems like the javascript never is able to find the CPE when it is on a master page.  I have an DropDownList on the page and when certain items are selected, i want to collapse or expand when others are selected.  It seems to work fine on a regular page, but not when it is a page nested in a master page.  It is adding a suffix to the CPE and javascript is unable to find it.  any help would be much appreciated!<script type="text/javascript" language="javascript">        function ExpandCollapse() {            var e = document.getElementById("<%=DropDownList.ClientID%>")            var strUser = e.options[e.selectedIndex].value;            var collPanel = document.getElementById("<%=CPE.ClientID%>")            if (collPanel = null)                alert('No panel found');            if (strUser = "Collapse")    

Deploying master pages in sharepoint 2007

Present situation:   Client has dev environment and they have customized the default page which comes ootb and is in Page Library. Also Created Master page using Sharepoint designer, and made that master page as the default master page for the site. The proposed solution: For promoting to different environments we will have to move packages WSP's across environments.   The present situation: All the environments were restored by using site collection backup and restore option (stsadm -o restore ...)   The Problem: Can we overwrite the master pages, page templates which are presently in master page gallery and page library by using feature   Or is there a better way of doing this.   Can somebody specify a better option for promoting.

master pages / connecting to databases / classes

I have a scenario where I pick up users and query them from active directory for a project, I've put the connection to database etc into the master page.cs for the meantime.Questions are:This is probably not the best place to put the connection query code, as it will do the query everytime the user goes to another page...correct?Would a better scenario be to pick the userDetails up on initial contact then carry the userDetails to each other page, can you use sessions to check if it is indeed that user? Thinking PHP here.Any thoughts would be appreciated!

master pages - how to access content page from master page?

Hello,I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be  triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists.  You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?
