Setting Item Level Permissions Programmatically

Here is how you can set item level permissions for a document library/list in sharepoint.

public string ItemLevelPermissions(string SiteAddress)


        string ReturnResult = "";


               using (SPSite WebApp = new SPSite(SiteAddressHere))

                   using (SPWeb Site = WebApp.OpenWeb())

                      SPList list = Site.Lists["MyDocLib"];

                      SPListItem item = list.Items[0];

                      SPRoleDefinition RoleDefinition = Site.RoleDefinitions.GetByType(SPRoleType.Contributor);

                      SPRoleAssignment RoleAssignment = new SPRoleAssignment("<DomainNameHere>\\<UserNameHere>", "EmailAddressHere", "GiveNameHere", "GiveNotesHere");








        catch (Exception ex)


            ReturnResult += "Sorry the permissions could not be set for the item due to the following exception: " + ex.Message;


        return ReturnResult;

Hope this helps–

    Can you give me an idea of how this would be deployed? How would it be activated and used?

    Hi David,

    There could be multiple scenarios. One of them could be to put this into an event handler which would set permissions on any new item that is just added (i.e. on ItemAdded event). For writing, deploying and activating such an event handler, look here:


    Just replace email code with the code above and you should be good to go!

    I’m not clear on what GiveNameHere and GiveNotes should be.
    I have an existing event receiver and I want to give the author who just created the item rights and deny everyone else who by default has access to the folder
