var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
all = JsonConvert.DeserializeObject<Allorders>(responseString);
ScriptManager.RegisterStartupScript(this, typeof(Page), "OnClientClicking", "divCloseAcntopen();", true);
GetAllOrders();
IdOfOrder=all.id;
GetordedsdsdsrById(IdOfOrder);

           contentType: "application/json; charset=utf-8",
           dataType: "json",
           success: function (response)
           {
               for (var k = 0; k < 6; k++)
               {
                //$('#tblEmployee').append('<tr> <td>' + response.d[1].id + '</td>  <td>' + response.d[1].status + '</td> <td>' + response.d[1].side + '</td></tr>');
