U can use request.querystring. refer below code it may helpful to u.. in .cs add this event: protected void GridView1_RowCommand(object sender GridViewCommandEventArgs e) { if (e.CommandName == passdata) { Response.Redirect(~/studprof.aspx?T_ID= + e.CommandArgument.ToString()); } } now you can able to get the id in new form. just get that id and pass that id to database to get the info of particular id. to get the id in next page: string id = Request.QueryString[ T_ID ];
