how to display the each row of gridview in a separate page in asp.net?

foreach (GridViewRow gr in GridView1.Rows)
{
   if (gr.RowType == DataControlRowType.DataRow)
   {
      string strQuery1 = "select id,studentname,gender" + " from student";
      DataTable dt = new DataTable();
      SqlConnection con = new SqlConnection
                (ConfigurationManager.AppSettings["connection"].ToString());
      SqlDataAdapter sda1 = new SqlDataAdapter();
      SqlCommand cmd1 = new SqlCommand(strQuery1);
      cmd1.CommandType = CommandType.Text;
      cmd1.Connection = con;
      try
      {
          con.Open();
          sda1.SelectCommand = cmd1;
          sda1.Fill(dt);                   
      }
      catch (Exception ex)
      {
          throw ex;
      }
      finally
      {
          con.Close();
          sda1.Dispose();
          con.Dispose();
      }
      GridView2.DataSource = dt;
      GridView2.DataBind();
   }                
}
