sending parameters to wcf service for chart

[inanc]

Hi,
I have a problem with the chart component.
I have a wcf service for retrieving data for the kendo ui chart.

<script type="text/javascript">

       $(document).ready(function () {

           $("#chart").kendoChart({

               dataSource: {

                   transport: {

                       read: {

                           type:"post",

                           url:"http://localhost:1038/Services/ProductService.svc/jIlBazliAnaliz",

                           dataType: "json",

                           data: '{BasTar:"2011-01-01",SonTar:"2011-12-31"}'

                           }

                   }

               },

               seriesDefaults: {

                   type: "column"

               },

               series: [{

                   field: "Sayi",

                   name: "Sayi"

               }],

               categoryAxis: {

                   field: "IlAdi",

                   labels: {

                       rotation:-90

                   }

               }

           });

       });

 

   </script>

I just would like to transfer two parameters by using the line ;

 data: '{BasTar:"2011-01-01",SonTar:"2011-12-31"}'

and my service side is 
in IProductService.cs

[OperationContract]

        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "jIlBazliAnaliz")]

        IList<ModelIlBazliAnaliz> jIlBazliAnaliz(DateTime BasTar, DateTime SonTar);

and in ProductService.svc.cs

 public IList<ModelIlBazliAnaliz> jIlBazliAnaliz(DateTime BasTar, DateTime SonTar)
        {
            IList<ModelIlBazliAnaliz> Iller=new List<ModelIlBazliAnaliz>();
            using (mxKalibrasyonEntities client = new mxKalibrasyonEntities())
            {
                var bak = client.kal_IlBazliAnaliz(BasTar, SonTar).ToList();
                foreach (var kalIlBazliAnalizResult in bak)
                {
                    Iller.Add(new ModelIlBazliAnaliz
                                  {
                                      Sayi = kalIlBazliAnalizResult.Sayi.Value,
                                      Oran = kalIlBazliAnalizResult.Oran.Value,
                                      IlAdi = kalIlBazliAnalizResult.IlAdi
                                  });
                }
                return Iller;
            }
        }

The issue is I am getting always null (0001-01-01) date value in the  ProductService.svc.cs .

If ı don't use any parameters, I mean with the

public IList<ModelIlBazliAnaliz> jIlBazliAnaliz() ;

without any parameters , my chart works great. But it is an obligation to have the chart filled for some time intervals. 


I wonder how can I send the BasTar and SonTar datetime parameters to the wcf service? I think this is possible.
Kind regards.

Hello Inanc,

You should make the following modifications in order to send the dates as parameters to the service:

1. Convert the dates to the Microsoft date format.
2. Specify the content type of the request.
3. Use the transport parameterMap function to convert the object to JSON.
4. In the service method change the BodyFormat to wrapped.

For example:

transport: {
    read: {
        type: "POST",
        url:"http://localhost:1038/Services/ProductService.svc/jIlBazliAnaliz",
        dataType: "json",
        contentType: "application/json; charset=utf-8"
    },
    parameterMap: function (options, operation) {
        var  data  = {
            BasTar: dateToWcfFormat("2011-01-01"),
            SonTar: dateToWcfFormat("2011-12-31")
        }

        return JSON.stringify(data);
    }
}

....

function dateToWcfFormat(dateString) {
    var date = new Date(dateString);
    var parsedDate = '\/Date(' + date.getTime() + '-0000)\/';
    return parsedDate;
}

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json,BodyStyle = WebMessageBodyStyle.WrappedRequest, UriTemplate = "jIlBazliAnaliz")]
IList<ModelIlBazliAnaliz> jIlBazliAnaliz(DateTime BasTar, DateTime SonTar);
