I am dynamically creating a series of tab, each with a gridview binding to data. Everything works great but I would like to allow sorting and paging.  I have tried several example I found online but nothing seems to work correctly.

What is the easiest way to achieve this?  When a create a Sorting event, I can't see the gridview control.  Does this event need to be part of the loop?

Any advice is appreciated.  My code to create the tabs and gridviews is below:
************************************************************************************************
protected void createMyOrgTabs()
        {
            tabCY.HeaderText = DateTime.Now.Year.ToString();

            //Create SQL Connection
            SqlConnection cn = new SqlConnection();
            cn.ConnectionString = ConfigurationManager.ConnectionStrings["myConnection"].ConnectionString;
            cn.Open();

            //Run Insert Stored procedure
            SqlCommand cmd = new SqlCommand();
            SqlDataReader rs;
            cmd.CommandText = "myCountProcedure";
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter("@param1", Session["param"].ToString()));
            cmd.Connection = cn;
            rs = cmd.ExecuteReader();
            rs.Read();

            int Count = Convert.ToInt32(rs["value"]);
           
            //Clear Parameters
            cmd.Parameters.Clear();
           
            //Close Datareader
            rs.Close();
           
            //Close Connection
            cn.Close();
            //Dispose Connection
            //cn.Dispose();
           
            for(int i = 1; i <= Count; i++)
            {
                //Create Dynamic TabPanels
                AjaxControlToolkit.TabPanel tp = new AjaxControlToolkit.TabPanel();
                tp.ID = tp + i.ToString();
                tp.HeaderText = DateTime.Now.AddYears(-i).Year.ToString();
                tabMyOrgs.Controls.Add(tp);

                //Open SQL Connection
                cn.Open();

                //Run Insert Stored procedure
                cmd.CommandText = "myDetailProcedure";
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.Add(new SqlParameter("@param1", Session["param"].ToString()));
                cmd.Parameters.Add(new SqlParameter("@param2", DateTime.Now.AddYears(-i).Year.ToString()));
                cmd.Connection = cn;
                rs = cmd.ExecuteReader();

                DataTable dt = new DataTable();
                dt.Load(rs);
                //Session["myDT"] = dt;
                dt.DefaultView.Sort = "orgName";

                //Create Year Label
                TextBox lblYear = new TextBox();
                lblYear.Text = DateTime.Now.AddYears(-i).Year.ToString() + " Organizations";
                lblYear.CssClass = "id";

                //Create Gridview
                GridView gvMyOrgs = new GridView();
                gvMyOrgs.DataSource = dt.DefaultView;
