Datasource to a Webservice JSON

[George]

I am trying to use a ASP.NET Webservice with KendoUI Datasource. For example:

$("#grid").kendoGrid({

    dataSource: {

        data:airports,

        schema: {

            data: 'd'

        }

    },

    columns: [

        {

            field: "airportName",

             

        },

        {

            field: "airportCode"

        }

    ]

});​

The problem is that the json being returned is:

d: "[{"airportName":"BDL:Bradley International Airport, CT","airportCode":"BDL"},{"airportName":"HVN:Tweed New Haven Regional Airport, CT","airportCode":"HVN"},{"airportName":"EWR:Newark Liberty Intl, NJ","airportCode":"EWR"},{"airportName":"HPN:Whiteplains Airport,NY","airportCode":"HPN"},{"airportName":"JFK:John F. Kennedy Intl,NY","airportCode":"JFK"},{"airportName":"LGA:La Guardia Airport,NY","airportCode":"LGA"}]

};"

Note the quote after the d:
This is being added by the Webservice because I am using Newtonsoft.Json.JsonConvert.SerializeObject to create the json. I am using Newtonsoft because I have not found a was to serialize a generic List object.

So the question is:
1. How do I get DataSource to work with the quoted results?
or
2. How do I get the webservice to not to quote the results?

The Webservice code is:

[WebMethod()]

public string GetAirportList()

{

    List<Airport> Airports = new List<Airport>();

    Airports.Add(new Airport {

        airportCode = "BDL",

        airportName = "BDL:Bradley International Airport, CT"

    });

    Airports.Add(new Airport {

        airportCode = "HVN",

        airportName = "HVN:Tweed New Haven Regional Airport, CT"

    });

    Airports.Add(new Airport {

        airportCode = "EWR",

        airportName = "EWR:Newark Liberty Intl, NJ"

    });

    Airports.Add(new Airport {

        airportCode = "HPN",

        airportName = "HPN:Whiteplains Airport,NY"

    });

    Airports.Add(new Airport {

        airportCode = "JFK",

        airportName = "JFK:John F. Kennedy Intl,NY"

    });

    Airports.Add(new Airport {

        airportCode = "LGA",

        airportName = "LGA:La Guardia Airport,NY"

    });

    return Newtonsoft.Json.JsonConvert.SerializeObject(Airports);

}

Please help. (I've been tearing my hair out for two days on this).

I found the problem with my WebMethod:
Changing the return datatype to an array of my object type removed the need to NewtonSoft:

[WebMethod()]

public Airport[] GetAirportList()

{

    List<Airport> Airports = new List<Airport>();

    Airports.Add(new Airport {

        airportCode = "?",

        airportName = ""

    });

    Airports.Add(new Airport {

        airportCode = "BDL",

        airportName = "BDL:Bradley International Airport, CT"

    });

    Airports.Add(new Airport {

        airportCode = "HVN",

        airportName = "HVN:Tweed New Haven Regional Airport, CT"

    });

    Airports.Add(new Airport {

        airportCode = "EWR",

        airportName = "EWR:Newark Liberty Intl, NJ"

    });

    Airports.Add(new Airport {

        airportCode = "HPN",

        airportName = "HPN:Whiteplains Airport,NY"

    });

    Airports.Add(new Airport {

        airportCode = "JFK",

        airportName = "JFK:John F. Kennedy Intl,NY"

    });

    Airports.Add(new Airport {

        airportCode = "LGA",

        airportName = "LGA:La Guardia Airport,NY"

    });

    return Airports.ToArray;

}

Now the returned JSON is not quoted.
