Displays site and sub-site content in a hierarchical tree that is expandable and collapsible


For use in Microsoft Windows SharePoint Services 3.0 and Office SharePoint Server 2007, this Site Content Web Part displays site and sub-site content in a hierarchical tree that is expandable and collapsible.


The Web Part uses SPHierarchyDataSourceControl to render site and sub-site content. SPHierarchyDataSourceControl is a data bound control that implements the IHierarchicalDataSource interface and derives from HierarchicalDataSourceControl. Unlike navigation provider SPNavigationProvider, it renders content in all sub-sites in addition to the current site. It is the same control used by SharePoint to render tree view in Quick Launch. And unlike the tree view, this web part renders HTML list tags instead of table tags.

The web part has several public properties:

  • TopSiteUrl - (Top Site URL) Server relative URL for a starting sub-site.
    For example: / for the root site or /PressReleases/2010 for a sub-site. Default is the current site.
  • ExpandMap - (Expand Map?) Expand all nodes on page load. Default is true
  • ShowWebChildren - (Show Sub-Sites?) Show sub-sites. Default is true
  • ShowFolderChildren - (Show Folders?) Show folders in libraries and lists. Default is true
  • IncludeDiscussionFolders - (Show Discussion Threads?) Show folders in discussion lists. If true, ShowFolderChildren must also be set to true for this to take effect. Default is false.
  • MaxLevels - (Maximum levels) Maximum number of node levels. Default is 0, which means unlimited
  • ListCssClass - CSS class name for the outermost <ul> tag
  • NodeCssClass - CSS class name for regular hyperlinked nodes

The Web Part uses two methods to include resources. JavaScript files are treated as Embedded Resources and images are treated as Class Resources. To reference Embedded Resources in code, use Page.ClientScript.GetWebResourceUrl and pass in the file in the form of [Default namespace].[Folder containing resource].[Filename of resource]. In AssemblyInfo.cs, include the file like:

[assembly: System.Web.UI.WebResource
   ("QuestechSystems.SharePoint.ClientScripts.SiteContentWebPart.js", "text/javascript")]

Class Resource files are referenced in code by calling SPWebPartManager.GetClassResourcePath. To package images as Class Resources in a Solution, include them in Manifest.xml, like:

<?xml version="1.0" encoding="utf-8" ?>

<Solution xmlns=""
    SolutionId="SolutionGuid" ResetWebServer="false">

        <Assembly Location="QuestechSystems.SharePoint.SiteMapWebPart.dll"
                <ClassResource Location="images\node-closed.gif" />
                <ClassResource Location="images\node-open.gif" />
                <ClassResource Location="images\node.gif" />
                    Culture=neutral, PublicKeyToken=AssemblyToken"
                    TypeName="*" Safe="True" />

        <FeatureManifest Location="SiteContentWebPart\Feature.xml" />


Since the project assembly is deployed to GAC, the deployment path for Class Resource files will be something like

The Web Part also uses a resource file to store all messages and property attribute UI strings. It demonstrates how to develop a custom class that inherits WebDescriptionAttribute, WebDisplayNameAttribute or CategoryAttribute and returns a localized string from your own Resource Manager.

The supplied Visual Studio 2008 solution includes all the support files you need to build and deploy this Web Part, minus the strong name key file (key.snk). It contains three projects: Deployment, Features and SharePoint. The SharePoint project contains source codes for the Web Part. The Features project contains all the features to support the SharePoint project. The Deployment project contains a pre-build script to aggregate all the files needed for deployment. It contains a Solution directory where a WSP file is generated and deployed by a post-build script.

This structure of Visual Studio projects is scalable to full blown MOSS/WSS development and deployment. You could add additional projects like SharePoint.ApplicationPages for customization of administrative layout pages. Within your projects, you could have other custom components like user and web controls, custom fields, feature receivers, etc.


Using stsadm, install solution file QuestechSiteContentWebPart.wsp in \Deployments\Solution\:

stsadm -o addsolution -filename QuestechSiteContentWebPart.wsp

Go to SharePoint Central Administration/Operations/Global Configuration-Solution Management. Deploy the installed solution to selected Web applications. In the site collection where the solution is deployed, activate Feature Questech Systems Site Content Web Part. After that, the Site Content Web Part should be available for you to add to pages.

CSS can be added to the master page or page layout to enhance styling of the web part. For example, if ListCssClass is set to scList, the following definitions will stylize the web part to look like the screenshot above.

.scList, .scList ul
    list-style: none;
    padding: 0;
.scList, .scList li
    margin: 0.66em 0;
.scList ul
    margin: 0.66em 2em;
