What you have to do is, first break the inherited permission and then assign new permission to the list items. The code to achieve the task is as follows: public static void SetItemLevelPermissions() { string sitrUrl = "https://sptenant.sharepoint.com/sites/contosobeta" ; using (var ctx = new ClientContext(sitrUrl)) { var web = ctx.Web; ctx.Load(ctx.Web, a => a.Lists); ctx.ExecuteQuery(); List list = ctx.Web.Lists.GetByTitle( "TestDocLibrary" ); string documentName = "TextFile.txt" ; CamlQuery camlQuery = new CamlQuery(); camlQuery.ViewXml = " \ "FileLeafRef\"" > "Text" >" +documentName + " " ; var items = list.GetItems(camlQuery); ctx.Load(items, a => a.Include(i => i.HasUniqueRoleAssignments)); ctx.ExecuteQuery(); foreach (var listItem in items) { if (!listItem.HasUniqueRoleAssignments) { listItem.BreakRoleInheritance( false , false ); ctx.ExecuteQuery(); } var roleAssignments = listItem.RoleAssignments; //Use below line, if you want to give access to a Group //var user_group = web.SiteGroups.GetByName("Site Members"); var user_group = web.SiteUsers.GetByLoginName( "i:0#.f|membership|admin@sptenant.onmicrosoft.com" ); var roleDefBindCol = new RoleDefinitionBindingCollection(ctx); // Add Role Definition i.e Full Controls, Contribute or Read rights etc.. roleDefBindCol.Add(web.RoleDefinitions.GetByType(RoleType.Contributor)); roleAssignments.Add(user_group, roleDefBindCol); ctx.Load(roleAssignments); listItem.Update(); ctx.ExecuteQuery(); } } } I found the reference here https://www.morgantechspace.com/2016/04/set-list-item-level-permission-using-csom-c-sharp.html

Hi Kamal, Why dont you use the OOTB settings to manage permissions only for the current user who creates the item?

Hi Kamal, When user adding the list item, map the user id or role id to apply the permission for those list items

Kamal Ayash · Answer

For example user X added a list item he will be the only granted permissions to read/contribute to this list item dynamically on list item creation. Please confirm if the scenario is enough or more information are needed. Thank you.

You can use SPD workflow or Event receiver to assign permission to current user on created item.
