How to set Item Level Permission for SharePoint 2007 (MOSS/WSS) List/Document Library Programmatically
Here is a piece of code (a function) to set Item Level Permission. You can use it as a Web Method in a custom Web Service. This method can be used from Applications outside of SharePoint, provided the user using this application has sufficient privilege to update lists/libraries etc.
public string ItemPermission(string SitePath)
{
string ReturnVal = "";
try
{
SPSite WebApp = new SPSite(SitePath);
SPWeb Site = WebApp.OpenWeb();
SPList list = Site.Lists["TestDocLib"];
SPListItem item = list.Items[0];
SPRoleDefinition RoleDefinition = Site.RoleDefinitions.GetByType(SPRoleType.Contributor);
SPRoleAssignment RoleAssignment = new SPRoleAssignment("<domain>\\<user>", "email", "name", "notes");
RoleAssignment.RoleDefinitionBindings.Add(RoleDefinition);
if(!item.HasUniqueRoleAssignments)
{
item.BreakRoleInheritance(true);
}
item.RoleAssignments.Add(RoleAssignment);
item.Update();
}
catch (Exception ex)
{
ReturnVal += "Permission not set, reason: " + ex.Message;
}
return ReturnVal;
}

Hi Taki, This code can be used by the administrator or users with sufficient privilege to change item level permission for the other users. This code can be implemented in a custom web part, in an application (Layouts) page or in a custom web services.Anonymous

How could you use this code to restrict permission to a folder or document level of a document library?Anonymous

Thanks for the useful code. But in some cases it's much better to take some tools that can make just the same thing in several clicks. In this situation I would use something like <a href="http://dl.scriptlogic.com/landing/beta/Security-Explorer-for-SharePoint.aspx">security explorer for SharePoint</a>. I found this tool not too long ago but I'm amazed at how it makes common permission operations easier. For example, using tree-like view of SharePoint farm and all sites you can manage SharePoint security permissions, permission levels and SharePooint groups in the most easiest and visual way.Anonymous

Hi We have a client requirement. The client created a default template where in he will specify the each user role for document library under project site. So when the client creates a new project site, the permissions for each of document library should inherit from this custom template rather than MOSS default permission settings. Is it possible to programatically over ride the MOSS default permission setting and give rights using custom template? Please let us know the details (including table names, sample code if possible)Anonymous

Thanks for the code. Is there a way to set permissions to a view? I have a registration form with several views filtered by a dropdown list of locations. I need to restrict various groups read access to this list to only see the view sorted by their location.Anonymous

Someone above was wondering how to establish the above example with a group. Simply replace: SPRoleAssignment RoleAssignment = new SPRoleAssignment("<domain><user>", "email", "name", "notes"); RoleAssignment.RoleDefinitionBindings.Add(RoleDefinition); With the following: SPGroup spGroup = WebApp.Groups["NameOfGroup"]; SPRoleAssignment RoleAssignment = new SPRoleAssignment(spGroup); RoleAssignment.RoleDefinitionBindings.Add(RoleDefinition); item.RoleAssignments.Add(roleAssignment ); Everything else should be the same.Anonymous

I was wondering if you knew a way to set permissions to a customized page. I created a custom page and attached a master page using SPD. My entire site is public facing, and several areas are accessible. I have lists that are locked down by permission based and was wondering if I could apply that permission idea to an individual page. Do you know if this is possible? Any ideas would be great!Anonymous

HI I have created specific Views in the particular SP site and now I need to ensure that my client can access only specific views that are meant for their eyes. I do not want them to See or access the other views from the View drop-down. Is there a way to restrict acces to views? I tried by creating a new library and then copying the .aspx view file but it did not work. Appreciate your help. Thanks much JeenaAnonymous

Sorry to be nitpicky, but you should be using the using(...){} blocks in there to ensure those unmanaged objects are properly disposed. Thanks for the code example though I get the pointAnonymous
