[RESOLVED] Display Checkboxlist as menu item

I have a menu control in my website where menu items(parent)  and sub menu items(child) are populate through database.

In below code ParentId=0 when its a menu item and ParentId > 0 when it's a sub menu item. The code is working fine.

if(!IsPostBack)
            {
                SqlConnection sqlConnection;
            
                string dbConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
                sqlConnection = new SqlConnection(dbConnectionString);
                DataSet ds = new DataSet();
                DataTable dt = new DataTable();
            
                using (sqlConnection)
                {
                    SqlCommand command = new SqlCommand("proc_GetCategories", sqlConnection);
                    command.CommandType = CommandType.StoredProcedure;
                    sqlConnection.Open();
                    SqlDataAdapter da = new SqlDataAdapter();
                    da.SelectCommand = command;
                    da.Fill(ds);
                    dt = ds.Tables[0];
                    DataRow[] drowpar = dt.Select("ParentId=" + 0);

                    foreach (DataRow dr in drowpar)
                    {
                        menuCategory.Items.Add(new MenuItem(dr["CategoryName"].ToString(),
                                dr["CategoryID"].ToString()));
                    }

                    foreach (DataRow dr in dt.Select("ParentID >" + 0))
                    {
                        MenuItem mnu = new MenuItem(dr["CategoryName"].ToString(),
                                       dr["CategoryID"].ToString());
                        menuCategory.FindItem(dr["ParentID"].ToString()).ChildItems.Add(mnu);
                    }
                }
            }

Now in order to insert the menu items in database I want to create a checkboxlist with same parent child relationship as menu-submen control.

For example if I have 5 menu items with 3 sub menu items displayed each then in the same maneer checkboxlist should display 5 parent check box

with 3 checkbox child items each. On select the parent checkbox all child checkbox should be checked. Each checkbox select will have a id with it like it is with menu item.

Please help me in achieving this.

Please see the example below
