I go through lots of site for select query on datatable. But most of the time I not get suitable solution. So, at last I use linq to filter data from datatable. So I share my code below: DataTable dt = new DataTable(); string sqlStatement1 = "select * from hsswith_view where cp_amount<='" + bug_amount + "' and no_of_days >='" + no_of_days + "' or ep_amount<='" + bug_amount + "' and no_of_days >='" + no_of_days + "'"; SqlCommand sqlCmd1 = new SqlCommand(sqlStatement1, connection); SqlDataAdapter sqlDa1 = new SqlDataAdapter(sqlCmd1); sqlDa1.Fill(dt1); var query = from r in dt1.AsEnumerable() where r.Field<string>("pax") == no_person select new { entry_id = r["entry_id"].ToString(), pax = r["pax"].ToString(), package = r["package"].ToString(), no_of_days = r["no_of_days"].ToString(), cp_amount = r["cp_amount"].ToString(), ep_amount = r["ep_amount"].ToString() }; GridView1.DataSource = query; GridView1.DataBind(); First of all I select data using one select query and fill it at datatable(dt1). Now I write linq query to extract data from dt1 datatble and bind the values at gridview. These much.
