How to:Extend the Navigation Provider

You can extend the navigation provider in Microsoft Office SharePoint Server 2007 by deriving a custom provider class from any of the default site map providers. Deriving from an Office SharePoint Server 2007 site map provider supplies several benefits such as navigation node caching and security trimming. The following code example derives from the PortalSiteMapProvider class and demonstrates how to add items to the site map provider. Although the site map provider classes have approximately twenty abstract or virtual methods, only a small number must be overridden and implemented in a custom site map provider. Create a Microsoft Visual C# class library project with following code, add the required references, and then build the project. using System;using System.Collections.Generic;using System.Text;using Microsoft.SharePoint.Publishing;using Microsoft.SharePoint.Publishing.Navigation;using System.Web;using System.Web.UI.WebControls;using System.Configuration; namespace MyCustomNav ...

Customizing Navigation Controls and Providers

To customize navigation, you should rely on the ASP.NET Site Navigation mechanism, because it provides a standard, consistent, and easily managed solution. Customizing Web Display Controls (Menu, TreeView, and SiteMapPath) : You can customize the look and feel of standard display controls by using cascading style sheets (CSSs). You can also write your own ASP.NET 2.0 controls and use them in Office SharePoint Server 2007 navigation. To learn more, see the Menu class documentation. Note : Office SharePoint Server 2007 also provides default navigation components that you can customize, such as the Content By Query Web Part and the Table of Contents Web Part. You can configure these two controls to present a custom selection of links. To implement your own site map provider, you can derive a custom provider class from any of the default site map providers. Office SharePoint Server 2007 includes several default providers. You can also derive a custom provider class from the SiteMapProvid...

PortalSiteMapProvider

The PortalSiteMapProvider object is the true source of hierarchical navigation data and it provides the data to the PortalSiteMapDataSource object. The PortalSiteMapProvider retrieves nodes from the Windows SharePoint Services 3.0 SPNavigation store. You use the SPNavigation object to create static links and groupings. After you provide static links and groupings, the application merges in dynamic items that represent Web sites and pages with the static links and groupings. Office SharePoint Server 2007 also applies security trimming so that users see only the navigation items to which they have permission to navigate. Declare named providers in the application's web.config file to make them widely accessible. Declarations of the two most important PortalSiteMapProvider objects— CombinedNavSiteMapProvider and CurrentSiteNavSiteMapProvider—are shown in the following code. add name="CombinedNavSiteMapProvider" description= "MOSS 2007 provider for Combined naviga...

PortalSiteMapDataSource

The PortalSiteMapDataSource is a data source specific to Office SharePoint Server 2007 that retrieves data from the PortalSiteMapProvider object and exposes data according to the ASP.NET 2.0 hierarchical data source interface. The PortalSiteMapDataSource object specifies the name of the PortalSiteMapProvider object it uses to retrieve data through the ASP.NET 2.0 SiteMapProvider property. When the master page markup includes the DataSourceID="GlobalNavDataSource" attribute, the application returns a PortalSiteMapDataSource object. PublishingNavigation:PortalSiteMapDataSource ID="GlobalNavDataSource" Runat="server" SiteMapProvider="CombinedNavSiteMapProvider" ShowStartingNode="false" StartFromCurrentNode="true" StartingNodeOffset="0" TrimNonCurrentTypes="Heading" TreatStartingNodeAsCurrent="true" /> The properties are, ShowStartingNode - Affects whether the starting node is returned by ...

Horizontal and Vertical Menus

When you first create a site structure that includes a root or top-level site, more than one Web site, and pages and additional sites that are children of the top-level site, Office SharePoint Server 2007 creates two menus: a horizontal (top) menu, and a vertical (left) menu. Horizontal and vertical menus are declared in master page markup. The following example declares a horizontal menu. SharePoint:AspMenu ID="GlobalNav" Runat="server" DataSourceID="GlobalNavDataSource" Orientation="Horizontal" StaticDisplayLevels="1" MaximumDynamicDisplayLevels="1" /> The vertical menu is declared similarly, but uses different properties from the horizontal menu. These properties are identical to those available on the ASP.NET 2.0 Menu control. The following are the properties included by default in master page markup for both horizontal and vertical menus: DataSourceID - Specifies the data source control that provides the hierarchical...

Working with Menus and Navigation Objects

Any declaration of Horizontal or Vertical menu instructions for navigation in XML for the master page, two classes are used to make the navigation work: PortalSiteMapDataSource PortalSiteMapProvider The PortalSiteMapProvider object provides the site hierarchy (navigation structure) and monitors the relationship between nodes.Many named instances of this site map provider are listed in the web.config file, and are also available through static properties on this class that the master pages in Office SharePoint Server 2007 deliver. Office SharePoint Server 2007 uses these named instances to provide data to the horizontal and vertical navigation menus. The application shares named instances across all Web requests on the current application domain. The class stores no session information. If necessary, session information is stored on the HttpContext class. The PortalSiteMapDataSource object maps navigation features from the PortalSiteMapProvider and filters navigation elements to de...

Customize Navigation, How?

Most Web sites employ some form of customized user interface (UI) that provides users with visual clues on how to navigate in the site more easily, and find the information they need. Although the look and feel (or branding) can vary from site to site, the same basic navigation elements are usually present, such as navigation bars and menus that expose options a user can choose to navigate to a subsite or page. you can customize it through programmatically and also through the UI, including: Using the provider and data source APIs to customize the structure and behavior of vertical and horizontal menus. Understanding Navigation Settings UI options and using them to set up a site navigation hierarchy. Replacing the default navigation provider included in Office SharePoint Server 2007 with your own custom provider. Configuring multiple navigation providers for a site.

Sharepoint Pages Overview

SharePoint pages are built on the foundation of ASP.NET . As a SharePoint developer, you must be aware of two different types of SharePoint pages. These are Application pages and Site pages. Application pages, such as Settings.aspx, are used for all Windows SharePoint Services sites. Therefore, if you modify or extend the functionality in this type of page, your changes will apply to all SharePoint sites. Application pages are stored in the file system of the front-end Web server. They are located in the TEMPLATE\LAYOUTS folder in the Web Server Extensions path. Each SharePoint Web includes a virtual directory, named _layouts, that points to this physical location. So, for example, the Settings page is accessible by using the relative URL of /_layouts/Settings.aspx. In contrast, Site pages, such as Default.aspx, can be customized on a site-by-site basis. Newly-created sites start with site pages based on page templates on the front-end Web server. For example, sites based on the Team S...

Content Types in Sharepoint

Introduction Content types, a core concept used throughout the functionality and services offered in Windows SharePoint Services 3.0, are designed to help users organize their SharePoint content in a more meaningful way. A content type is a reusable collection of settings you want to apply to a certain category of content. Content types enable you to manage the metadata and behaviors of a document or item type in a centralized, reusable way. Click here for more... Site and List Content Types You create a content type at the site level. This site content type acts as a template that is independent of any specific list or library. That site content type is then available on any child site.When you create a site content type, it becomes available on any child site. At this point, the site content type is available to be added to lists within the site, but has not actually been added to any specific site list. For more click here...

Manage Alerts

Web sites based on Microsoft Windows SharePoint Services are meant to help groups of users work together, they tend to grow quickly and change often. Keeping up with these changes can be difficult for users, especially if they aren't checking on the site every day. To help users stay in touch with changes on a site, Windows SharePoint Services includes a feature called Alerts, an e-mail notification service. When documents, lists, or items in a list on a server running Windows SharePoint Services are created, modified, or deleted, users who sign up for alerts receive messages informing them that changes have been made. The Following topics are covered regarding "Alert" Alerts Overview Default Timer Interval Predefined Alert Templates Alert Template Format Modifying the Appearance of Alerts Event Logs in Windows SharePoint Services Alert Object Model Implementing Alert Handlers Still more to come...
