post ur aspx.cs file... Check ur class name in that..

Use this Line in Line 1 and try..
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="_Default" %>

[This way instead of needing permissions for all tables for each group they all default to false unless I specifically say that the group has permission. so if 1 group has access to 1 folder out of 5 it only needs 1 permission row instead of 5?]
-- Yes..That I mentioned in the beginning itself... Usergroup 3 has access to folder 4 and that is set in 3 rd table..

Its good to have a Primary Key on each table(Must in Entity framework)..Thats why the SetAccessId.. In User table itself relate the usergroup,and you can manage the user to two usergroups based on the usergroup table design..
