does any one know how to do a query string from aspx page to handler page?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Linq;
using System.IO;
using System.Net;


namespace Nap
{
    public partial class About : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

            Response.Headers.Add("Content-Type", "image/jpeg");

        }

        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            string PhotoPath = "";
            // Get the currently selected row. Because the SelectedIndexChanging event
            // occurs before the select operation in the GridView control, the
            // SelectedRow property cannot be used. Instead, use the Rows collection
            // and the NewSelectedIndex property of the e argument passed to this 
            // event handler.
            GridViewRow row = GridView1.Rows[GridView1.SelectedIndex];

            PhotoPath = row.Cells[5].Text;
            
            //TextBox1.Text = PhotoPath;
        }
    }
}
