SharePoint: How to hide All Site Content links for unprivileged users

June 8th, 2012 No comments

    If you need to hide All Site Content links for unprivileged users, follow the steps shown below.

All Site Content Links

Your application’s master page is to be modified. If you use a built-in master page (for example, v4.master for 2010 or default.master for 2007), I recommend to create a full copy of the built-in one and deploy it. These steps are described in the article SharePoint: How to create a custom master page.

In the master page, locate all places where _layouts/viewlsts.aspx is pointed out. You’ll likely find several controls (for example, a MenuItemTemplate, a SPLinkButton and so on), which render All Site Content links one way or another. These controls can be divided into three groups described below.

The controls exposing the PermissionsString property

The controls expose such opportune property as PermissionsString defining a permission set the user must have in order to see the content the controls provide. For this group of controls PermissionsString is likely set by default to ViewFormPages. That is, if the user has permission to view forms, views and application pages, and enumerate lists, he will have access to All Site Content links displayed by these controls. So, set PermissionsString to ManageWeb in order that the links in question would be visible only for users able to perform administration tasks for the Web site (e.g. content managing, features activating and deactivating and so on). For example, within your copy of v4.master you’ll definitely run into such controls as MenuItemTemplate and ClusteredSPLinkButton declared as follows:

<SharePoint:SiteActions id="SiteActionsMenuMain" runat="server" ...>
  <CustomTemplate>
    <SharePoint:FeatureMenuTemplate ID="FeatureMenuTemplate1" runat="server" ...>
      ...
        <SharePoint:MenuItemTemplate runat="server" 
          id="MenuItem_ViewAllSiteContents"
          Text="<%$Resources:wss,quiklnch_allcontent%>"
          Description="<%$Resources:wss,siteactions_allcontentdescription%>"
          ImageUrl="/_layouts/images/allcontent32.png"
          MenuGroupId="300"
          Sequence="302"
          UseShortId="true"
          ClientOnClickNavigateUrl="~site/_layouts/viewlsts.aspx"
          PermissionsString="ViewFormPages"
          PermissionMode="Any" />
      ...
    </SharePoint:FeatureMenuTemplate>
  </CustomTemplate>
</SharePoint:SiteActions>

The control represents an item in the drop-down Site Actions menu.

Another control is ClusteredSPLinkButton

<asp:ContentPlaceHolder id="PlaceHolderQuickLaunchBottom" runat="server">
  ...
  <SharePoint:UIVersionedContent id="PlaceHolderQuickLaunchBottomV4" UIVersion="4" runat="server">
    <ContentTemplate>
      <ul class="s4-specialNavLinkList">
        ...
        <li>
          <SharePoint:ClusteredSPLinkButton
            id="idNavLinkViewAllV4"
            runat="server"
            PermissionsString="ViewFormPages"
            NavigateUrl="~site/_layouts/viewlsts.aspx"
            ImageClass="s4-specialNavIcon"
            ImageUrl="/_layouts/images/fgimg.png"
            ImageWidth=16
            ImageHeight=16
            OffsetX=0
            OffsetY=0
            Text="<%$Resources:wss,quiklnch_allcontent_short%>"
            accesskey="<%$Resources:wss,quiklnch_allcontent_AK%>"/>
        </li>       
      </ul>
    </ContentTemplate>
  </SharePoint:UIVersionedContent>
</asp:ContentPlaceHolder>

The control represents a link in the Quick Launch Bar.

All Site Content Quick Launch Link

So, change the PermissionsString property of the above controls to ManageWeb.

The controls, which are wrapped in a SPSecurityTrimmedControl

The controls lies in SPSecurityTrimmedControl. SPSecurityTrimmedControl renders the content it contains (Html or other controls) depending on the current user’s permissions. It exposes the same PermissionsString property. Thus, set the property to ManageWeb. Within a master page based on v4.master there is a SPLinkButton surrounded by the SPSecurityTrimmedControl, see the following markup:

<asp:ContentPlaceHolder id="PlaceHolderQuickLaunchTop" runat="server">
  <SharePoint:UIVersionedContent UIVersion="3" runat="server">
    <ContentTemplate>
      <h3 class="ms-standardheader">
        ...
        <Sharepoint:SPSecurityTrimmedControl runat="server" PermissionsString="ViewFormPages">
          <div class="ms-quicklaunchheader">
            <SharePoint:SPLinkButton id="idNavLinkViewAll" 
              runat="server" NavigateUrl="~site/_layouts/viewlsts.aspx" 
              Text="<%$Resources:wss,quiklnch_allcontent%>" 
              accesskey="<%$Resources:wss,quiklnch_allcontent_AK%>"/>
          </div>
        </SharePoint:SPSecurityTrimmedControl>
      </h3>
    </ContentTemplate>
  </SharePoint:UIVersionedContent>
</asp:ContentPlaceHolder>

Here the SPLinkButton represents the All Site Content link in the Quick Launch Bar as well, but it’s displayed for applications migrated from SharePoint 2007 with the previous version of UI. So, set the PermissionsString of the surrounding SPSecurityTrimmedControl to ManageWeb.

All other controls

The controls from the last group are not wrapped in SPSecurityTrimmedControl and don’t provide any ability to limit the access to their contents for unprivileged users. What is needed to do is put such controls into SPSecurityTrimmedControl and set the PermissionsString property of the last to ManageWeb. Within your copy of v4.master there are a few such controls:

<Sharepoint:UIVersionedContent runat="server" UIVersion="3">
  <ContentTemplate>
    <Sharepoint:SPNavigationManager id="TreeViewNavigationManager" runat="server" ...>
      <table class="ms-navSubMenu1" ...>
        <tr>
          <td>
            <table class="ms-navheader" ...>
              <tr>
                <td nowrap="nowrap" id="idSiteHierarchy">
                  <SharePoint:SPLinkButton runat="server" id="idNavLinkSiteHierarchy"
                    NavigateUrl="~site/_layouts/viewlsts.aspx"
                    Text="<%$Resources:wss,treeview_header%>" 
                    accesskey="<%$Resources:wss,quiklnch_allcontent_AK%>"/>
                </td>
              </tr>
            </table>
          </td>
        </tr>
      </table>
      ...
    </Sharepoint:SPNavigationManager>
  </ContentTemplate>
</SharePoint:UIVersionedContent>

Here the All Site Content link is presented by SPLinkButton. It’s displayed under Quick Launch, when the previous version of UI is enabled and when the TreeView navigation option is turned on in Site Settings. Wrap the link into SPSecurityTrimmedControl. It may look like the following:

<Sharepoint:UIVersionedContent runat="server" UIVersion="3">
  <ContentTemplate>
    <Sharepoint:SPNavigationManager id="TreeViewNavigationManager" runat="server" ...>
      <SharePoint:SPSecurityTrimmedControl ID="SPSecurityTrimmedControl2" 
          runat="server" PermissionsString="ManageWeb">
        <table class="ms-navSubMenu1" ...>
          <tr>
            <td>
              <table class="ms-navheader" ...>
                <tr>
                  <td nowrap="nowrap" id="idSiteHierarchy">
                    <SharePoint:SPLinkButton runat="server" id="idNavLinkSiteHierarchy"
                      NavigateUrl="~site/_layouts/viewlsts.aspx"
                      Text="<%$Resources:wss,treeview_header%>" 
                      accesskey="<%$Resources:wss,quiklnch_allcontent_AK%>"/>
                  </td>
                </tr>
              </table>
            </td>
          </tr>
        </table>
      </SharePoint:SPSecurityTrimmedControl>
      ...
    </Sharepoint:SPNavigationManager>
  </ContentTemplate>
</SharePoint:UIVersionedContent>

Another control is declared as SPLinkButton too:

<Sharepoint:UIVersionedContent runat="server" UIVersion="4">
  <ContentTemplate>
    <Sharepoint:SPNavigationManager id="TreeViewNavigationManagerV4" runat="server" ...>
      <SharePoint:SPLinkButton runat="server" id="idNavLinkSiteHierarchyV4"
          NavigateUrl="~site/_layouts/viewlsts.aspx" 
          Text="<%$Resources:wss,treeview_header%>" 
          accesskey="<%$Resources:wss,quiklnch_allcontent_AK%>" 
          CssClass="s4-qlheader" />
      ...
    </Sharepoint:SPNavigationManager>
  </ContentTemplate>
</SharePoint:UIVersionedContent>

It’s a link in the treeview under Quick Launch, when the TreeView Navigation option is enabled in Site Settings. It can be modified to the following:

<Sharepoint:UIVersionedContent runat="server" UIVersion="4">
  <ContentTemplate>
    <Sharepoint:SPNavigationManager id="TreeViewNavigationManagerV4" runat="server" ...>
      <SharePoint:SPSecurityTrimmedControl ID="SPSecurityTrimmedControl3" 
          runat="server" PermissionsString="ManageWeb">  
        <SharePoint:SPLinkButton runat="server" id="idNavLinkSiteHierarchyV4"
            NavigateUrl="~site/_layouts/viewlsts.aspx" 
            Text="<%$Resources:wss,treeview_header%>" 
            accesskey="<%$Resources:wss,quiklnch_allcontent_AK%>" 
            CssClass="s4-qlheader" />
      </SharePoint:SPSecurityTrimmedControl>
      ...
    </Sharepoint:SPNavigationManager>
  </ContentTemplate>
</SharePoint:UIVersionedContent>

Summary

Let’s sum up. If you see a control exposing PermissionsString, set the property to ManageWeb. If a control is within a SPSecurityTrimmedControl, set the PermissionsString of the last one to ManageWeb as well. And finally, if it’s just a control, add a new SPSecurityTrimmedControl, place the first one in it and set the ManageWeb permission.

SharePoint: How to create a custom master page

May 26th, 2012 No comments

    Sometimes we need to add a JavaScript to, change layout or make other alterations in a master page that is used by a SharePoint application. Certainly, we can modify built-in master pages, but it’s far away from the best practices. Moreover, all changes we made may be lost after a regular SharePoint update. So, we should make a copy of a particular built-in master page, deploy it through a feature and set as default for our application instead of the built-in one.

Making a full copy

Let’s assume our application is bound to the V4.master (usually located in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\GLOBAL or C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS), which is default for SharePoint 2010. We make a full copy of the master page and name it MyV4.master.

If you still use SharePoint 2007, your application is likely bound to the default.master (usually located in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\GLOBAL). Create a full copy of it.

Creating a feature

In a new VisualStudio 2010 SharePoint project or in an existent one, we create a feature and call it, for example, MyMasterPageFeature. We add a Module to the project, let’s say MyMasterPage, put the MyV4.master into the Module and modify Elements.xml properly. Below is the possible project’s structure:

Structure of SharePoint Project containing Feature

Where the Elements.xml from the MyMasterPage Module should look like:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Module Name="MyMasterPage" Url="_catalogs/masterpage" Path="" RootWebOnly="FALSE">    
    <File Path="MyMasterPage\MyV4.master" Url="MyV4.master" Type="GhostableInLibrary" />
  </Module>
</Elements>

The manifest of the MyMasterPageFeature in design mode (or the feature.xml in a resultant wsp package) should look like the following:

<?xml version="1.0" encoding="utf-8"?>
<Feature xmlns="http://schemas.microsoft.com/sharepoint/" 
             Title="MySharePointProject Feature" 
             Description="MySharePointProject Feature" 
             Id="a1e26f45-41c5-4581-8b69-8385923ddd11" 
             Scope="Web">
  <ElementManifests>
    <ElementManifest Location="MyMasterPage\Elements.xml" />
    <ElementFile Location="MyMasterPage\MyV4.master" />
  </ElementManifests>
</Feature>

If it’s a new SharePoint project intended for the feature only, we can leave Package.Template.xml and MyMasterPageFeature.Template.xml without any changes.

For a SharePoint 2007 application or one migrated from it the possible project’s structure is shown below. The content of the xml files in question is the same as for 2010 version.

Subclassing MasterPage

On this stage I also suggest to subclass the master page‘s class. In this case you will have more control under the master page‘s rendering; it can be very useful in the future. For this, just add a new cs-file (for example, MyMasterPageClass.cs) to the project and put the following code into the file:

using System;
using System.Web.UI;

namespace MySharePointProject
{
    public class MyMasterPageClass : MasterPage
    {
        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
        }
    }
}

In the MyV4.master replace the line

<%@Master language="C#" %>

with the one like this

<%@Master language="C#" 
   Inherits="MySharePointProject.MyMasterPageClass,MySharePointProject, 
   Version=1.0.0.0, Culture=neutral, PublicKeyToken=acf3114812c89a34" %>

Deploying the wsp package and activating the feature

Ok, now we need to build the project, make a wsp package and deploy it. All these actions can be easily done from Visual Studio 2010, or, in case of SharePoint 2007, by means of WSPBuilder. If you prefer deploying wsp packages through PowerShell (SharePoint 2010 only), it’s mentioned here. Or use stsadm.exe for SharePoint 2007.

Make sure that the MyMasterPageClass is registered as safe control in a web.config corresponding to your SharePoint application:

<SafeControls>
	...
	<SafeControl Assembly="MySharePointProject, Version=1.0.0.0, 
                                  Culture=neutral, PublicKeyToken=acf3114812c89a34" 
                          Namespace="MySharePointProject" TypeName="*" 
                          Safe="True" SafeAgainstScript="False" />
	...
</SafeControls>

Now everything is ready to activate the feature, so we do this through the UI, PowerShell (SharePoint 2010 only) or stsadm.exe (SharePoint 2007 only).

Set the custom Master Page as Default

After the feature is activated we need to set the MyV4.master as Default. For already deployed SharePoint applications it can be done through the SharePoint Designer.

Set Default Master Page

For new applications we should provide something like this within our ONET.xml:

<Configurations>
    ...
    <Configuration ID="0" Name="Default" MasterUrl="_catalogs/masterpage/MyV4.master">
    ...
</Configurations>

Since that moment we have our own customizable master page and have a full control under what and how is being rendered.
