This page will have to run in the context of the site.
When a user submits the page, the page will also validate if the url that was entered is a valid SharePoint site.
Step 1 Add a link to the
Site Settings menu.
The first step is to create a link to the Site Settings menu. We will lock this down, so that it is only available for administrators. The easiest way to do this is by using a SharePoint Feature. How to install and activate can be found in the previous article. The feature xml for this feature looks like this
Title="Custom Navigation Site Menu items by Ton"
Description="My custom Site Menuitems for setting up navigation."
This is the XML for installing the feature. The file that is referenced in the ElementManifest node actually adds the menu item:
Title="Setup Custom Navigation"> Location="Microsoft.SharePoint.SiteSettings" GroupId="Customization"
A number of attributes further explained:
· Title – the title of the link
· Location – The location of the new action. This can be the Site Actions menu, edit menus, toolbars etc. I have picked “Microsoft.SharePoint.SiteSettings” to make it appear in the site settings page.
· GroupId – The group in which the action will appear. I have picked “Customization”, because this makes our action appear in the “Look and Feel” section of the site settings. You can add these sections yourself using a “CustomActionGroup”. See the WSS SDK for more details.
· RequireSiteAdministrator – This makes the option only appear for Site Administrators.
· UrlAction – The url to navigate to when the user clicks the link. By using the “~site” in the url, we make our administration page run in the context of the site.
After installing and activating the feature, our site administration now has a new item:
Step 2 – Create the administration page
In the second step we will create the CustomNavigation.aspx page that is referenced from the menuoption in step 1. The first step in making your administration page look like real SharePoint administration pages, is inheriting it from “WebAdminPageBase”, which is available in the “Microsoft.SharePoint.ApplicationPages” namespace. I created a new class library project and added a new class called “CustomNavigation”.
Our aspx page should use this code behind, and also register the namespaces and controls that we will use to build the page. I will not copy all code, you can find that in the attached ZIP file.
<%@ Assembly Name="Microsoft.SharePoint.ApplicationPages, Version=22.214.171.124, Culture=neutral, PublicKeyToken=71e9bce111e9429c"%>
<%@ Page Language="C#" Inherits="Eog.OfficeServer.ApplicationPages.CustomNavigation, Eog.OfficeServer.ApplicationPages, Version=126.96.36.199, Culture=neutral, PublicKeyToken=4765c72bbf274873" MasterPageFile="~/_layouts/application.master" %>
Step 3 – Add controls to the placeholders
Because our page inherits from WebAdminPageBase, we now have several placeholders that we need to populate. We don’t need to build the whole page, the masterpage does that for us, we just populate a few placeholder. The first placeholders are the title placeholders:
Setup Custom Navigation
The main content are of the page (called PlaceHolderMain) will re-use some standard control templates that are available in the ControlTemplates folder.
These are registered at the top of the page as well:
<%@ Register TagPrefix="wssuc" TagName="InputFormSection" src="~/_controltemplates/InputFormSection.ascx" %>
We start off creating a new section on the page for our “Local Navigation” settings. This can be done by using the InputFormSection control. The InputFormSection can have one or multiple controls. These are added within a “<Template_InputFormControls>“.
This template can have multiple controls. These controls are InputFormControl controls, that are a combination of the label and the control. They look like this:
LabelText="Navigation Expand Depth"
Title="Navigation Expand Depth"
Step 4 – Add OK and Cancel button
After adding the control to edit the values, we add the OK and Cancel button to the page. These are added in a special ButtonSection, that will be added just below the InputFormSection. The code for the OK button (see the zip for the rest):
Step 5 – Add validation
The last part of the aspx page at this stage is the validation of the page. Most out of the box administration pages add a FormDigest control to the page. This is a SharePoint control that adds security validation to the page. This is specific for the user requesting the page and the time it is requested. After some time it expires, making it impossible to post the page. I have not added this yet to my page, will write a post on it after I sorted this out.
The validation that we will add is a validator for checking if the url entered in the Navigation Parent field is a valid SharePoint site. Just after the InputFormTextbox, we add a CustomValidator:
Display = "Dynamic"
ErrorMessage = "Please enter a url for a SharePoint site."
Step 6 – Implement code-behind
The code to actually make the page work is implemented in the CustomNavigation.cs. First we need to ensure that users who are not administrator cannot access the page by using the url directly. That is easy J; just add these lines :
protected override bool RequireSiteAdministrator
You can find all code to load and save the siteproperties in the attached zip file. Saving a property to the property bag can be done like this:
// Store NavigationExpand in the property bag.
if (web.Properties["navigationexpand"].ToLower() != navigationExpandTextBox.Text.ToLower())
web.Properties["navigationexpand"] = navigationExpandTextBox.Text;
modified = true;
modified = true;
And don’t forget to call Update:
After saving the properties to the property bag, we will redirect the user back to the site settings page. The code to do that:
Step 7 – Deploy the administration page
The proper way to deploy our administration page in SharePoint 2007 is through a Solution Deployment package. I haven’t had the time to sort that out, but is a very nice way of deploying packages like this.

MOSS2007 takes a radically different approach to rendering pages, due mostly to the integration of Content Management Server features into the product and an ongoing effort on Microsoft’s part to migrate towards a more structured, data-bound architecture (i.e. CAML and XML). Much of what we learned customizing SPS2003 will still be applicable but a great deal of the behind the scenes machinery has changed. A good place to begin learning how to modify MOSS2007 to meet your needs is with default page customizations; changing the structure, appearance, and layout of the default site welcome pages.
Since MOSS2007 is built on ASP.NET 2.0, a solid understanding of master pages is required in order to grasp how site pages are constructed and rendered. A master page (any ASPX page with a .master extension) is nothing more than a template with placeholders for content, much like a regular ASP.NET page that invokes user controls to render content. In .NET 2.0 syntax, these placeholders are implemented using the <ASP:ContentPlaceHolder> tag. Placeholders can be nested, so that a top-level placeholder may have multiple levels of child placeholders, much like a parent DIV can have many nested child DIV’s.
The master page by itself usually contains very little actual content other than headers and navigation – it’s just a framework for one or more layout pages that comprise the body of the page. In MOSS2007, the master page DEFAULT.MASTER, located in WEB SERVER EXTENSIONS\12\TEMPLATE\GLOBAL, defines the standard top header and left navigation layout found throughout the basic site definitions. Unlike SPS2003, where the default page in each site definition contained all the code necessary to render the page, the new site definitions, located in 12\TEMPLATE\SITETEMPLATES, have a DEFAULT.ASPX page that references the master page but contains no actual content. Instead, the default page is built at runtime when the site is created by combining MASTER.DEFAULT with the layout page referenced in the PublishingPageLayout property of the Default.aspx File node of the Modules configuration in ONET.XML (~SiteCollection/_catalogs/masterpage/defaultlayout.aspx for the SPS site definition, which corresponds to 12\TEMPLATE\FEATURES\PORTALLAYOUTS\DEFAULTLAYOUT.ASPX in the server file structure). The combined file is then stored in the Pages list on the top-level site.
DEFAULT.ASPX = MASTER.DEFAULT + DEFAULTLAYOUT.ASPX
When you edit the default page using SharePoint Designer you are actually editing the combined code from two pages – the master page and the layout page. Fortunately, because the default page is stored in a list, the whole ghosting/unghosting issue no longer applies (hooray for that!); however, there is one major drawback – since the page doesn’t actually exist until the site is created, editing it only applies to the current site instance – new sites or subsites based on the same definition will have to edited manually each time they are created. To automate this process, the site definition must be modified in a similar manner to the methods used in SPS2003 but using the new master page methodology. Doing so requires making changes not just to a single default page but both the master and layout pages (we’ll cover creating new site definitions from scratch in a subsequent post).
The layout page works with the default page by specifying what content is to be placed in the placeholder zones using the <ASP:Content> tag and referencing the placeholder id. The page handler process then assigns the content in the layout page, which consists of the HTML markup we are used to seeing in SharePoint pages (server controls, web part zones, etc.), to the proper zone in the default page. The following illustration is a wireframe model of a combined DEFAULT.ASPX page with all the major placeholders, server controls, custom tags, content areas and publishing/web part zones placed in their proper context (click on the image to view it full size):
Blue areas in the model indicate placeholders, red is for server/user controls, purple represents new ASP-specific controls (in this case the breadcrumb navigation menu), green indicates the new PublishingWebControls objects, and grey is the standard web part zones. The yellow headers indicate the relationship between the default and layout pages. The final rendered page looks like this:
As you can see from the wireframe model, the page layout is not all that different from SPS2003, except that content is now separated from navigation by using two different file types. The beauty of this model is that changes to DEFAULT.MASTER are global; no more cutting and pasting code modifications into multiple site definitions. Likewise, the DEFAULTLAYOUT.ASPX page is also universal, making changes much easier to implement. If, for example, we wished to change the basic layout of the web part zones in the body of the page, we can modify the markup in DEFAULTLAYOUT.ASPX without touching the headers and navigation contained in the master page. We can also add content to the master page by using <ASP:Content> tags and specifying the placeholder with the ContentPlaceHolderId setting without actually modifying the master page itself.
In SPS2003 the customization process was cumbersome and inefficient; with the new master page model, Microsoft has given us far greater flexibility in customizing SharePoint sites to meet each organization’s unique requirements. In subsequent posts we will explore in greater depth the new MOSS2007 architecture, including the new list file structure, the long-overdue changes to the administration pages, and how to create new site definitions from scratch.
To add your own tab you will want to add your own unique DisplayCategory attribute to the configuration section of the WEBTEMP*.XML file for your new site definition.
