SharePoint OOB Item level Permission under List Settings

Question

Users & Roles:
Authors: User with author role can create a new item but can only edit/delete their own items and not other user items. They should not modify or view the list settings(Permission level - Contribute)
Editor: User with Editor role can create a new item and can Edit/Delete their own items and also other user items. They should not modify or view the list settings(Permission level - Contribute)
1. Created a new list.
2. In advance setting enabled "Item-level
Permissions" as follows,
For Read
Accesss selected "Read all items"
For Create
and Edit access selected "Create items and edit items that were created by the user"
Now, User with Editor access can't able to Edit/delete other user items but can able to Edit/Delete their own items(same as user with Author role).
Then i have changed the Editor access Permission level to
Edit. In Edit Permission level  i have enabled Override Check-Out
and disabled Manage Lists. But still user with Editor access doesn't satisfy the condition.
kindly help me on this to resolve the above issue.
For Read
Accesss select "Read items that were created by the user"
For Create
and Edit access select "Create items and edit items that were created by the user"
For Read
Accesss select "Read items that were created by the user"
For Create
and Edit access select "Create items and edit items that were created by the user"
For Read
Accesss select "Read items that were created by the user"
For Create
and Edit access select "Create items and edit items that were created by the user"

Hi Nishok,
Agree with Paul's opinion, you can create an event receiver to set Item Level Permission. Here is the snippet:
using System;
using System.Diagnostics;
using System.Threading;
using System.Windows.Forms;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Workflow;
namespace ItemLevelSecurity.ItemSecurity
/// <summary>
/// List Item Events
/// </summary>
public class ItemSecurity : SPItemEventReceiver
/// <summary>
/// An item was added.
/// </summary>
public override void ItemAdded(SPItemEventProperties properties)
SPSecurity.RunWithElevatedPrivileges(delegate()
try
using (SPSite oSPSite = new SPSite(properties.SiteId))
using (SPWeb oSPWeb = oSPSite.OpenWeb(properties.RelativeWebUrl))
//get the list item that was created
SPListItem item = properties.ListItem;
//get the author user who created the item
SPFieldUserValue valAuthor = new SPFieldUserValue(properties.Web, item["Created By"].ToString());
SPUser oAuthor = valAuthor.User;
//assign permissions to task author
AssignPermissionsToItem(item,oAuthor,SPRoleType.Reader);
//update the item
item.Update();
base.ItemAdded(properties);
catch (Exception ex)
properties.Status = SPEventReceiverStatus.CancelWithError;
properties.ErrorMessage = ex.Message;
properties.Cancel = true;
public static void AssignPermissionsToItem(SPListItem item, SPPrincipal obj, SPRoleType roleType)
if (!item.HasUniqueRoleAssignments)
item.BreakRoleInheritance(false, true);
SPRoleAssignment roleAssignment = new SPRoleAssignment(obj);
SPRoleDefinition roleDefinition = item.Web.RoleDefinitions.GetByType(roleType);
roleAssignment.RoleDefinitionBindings.Add(roleDefinition);
item.RoleAssignments.Add(roleAssignment);
