Hi there,
I am getting really crazy ... i tried everything for several days now and i am lost ... i am a newbie ... i know ... but please help me.
I wrote a simple HTML file. I connect to a very simple JSON service on a remote server. If i try with the URL "http://ip.jsontest.com" it works fine but with my own MCF service that also give correct JSON response (i tested it in JSONlint and you can try it your self on "http://extranet.atseven.nl/Freelance365_WS/Contracts.svc/getall") i just get the spinner of the igGrid component. The response of my JSON service is
{"BirthYear":1970,"FirstName":"Mark","LastName":"Bakker"}
The HTML code i use is:
<!doctype html>
<html>
<head>
<!-- Infragistics Combined CSS -->
<link href="Infragistics/css/themes/infragistics/infragistics.theme.css" rel="stylesheet" />

<script src="Infragistics/js/infragistics.lob.js"></script>
<script type="text/javascript">
var data_url = "http://extranet.atseven.nl/Freelance365_WS/Contracts.svc/getall";
var jsonp = new $.ig.JSONPDataSource({ dataSource: data_url });
$(function () {
$("#grid").igGrid({
width: "1000px",
dataSource: jsonp,
autoGenerateColumns: true,
});
</script>
</head>
<body>
<div id="grid"></div>
</body>
</html>
Are you sure it is returning a valid JsonP response? Or is returning straight json?
JsonP would be needed for cross domain request.
A jsonp response would be wrapped callback( {"mydata" : "not here"});
Hi mhead1,
I think it is a correct JSON response. When i use the URL http://ip.jsontest.com it is working correctly and this response is also not wrapped. The response from this URL looks like
{"ip": "94.212.234.218"} when i use the URL in a browser.
My own made MCF service response is almost the same when i look at the structure.
The URL is: http://extranet.atseven.nl/Freelance365_WS/Contracts.svc/getall
The response is: {"IP":"192.168.0.1"}
The code for the MCF service is:
<OperationContract> _
<WebGet(BodyStyle:=WebMessageBodyStyle.Bare, ResponseFormat:=WebMessageFormat.Json)> _
Function GetAll() As IPadres
The code for the class and the function is:
Function GetAll() As IPadres Implements IContracts.GetAll
Dim myIP As IPadres = New IPadres
With myIP
.IP = "192.168.0.1"
End With
Return myIP
End Function
End Class
Public Class IPadres
<DataMember> _
Public Property IP() As String
Get
Return m_IPadres
End Get
Set(value As String)
m_IPadres = value
End Set
End Property
Private m_IPadres As String
Try enabling the return of JSONP instead.
Read this article and see how to wrap your return like a function and then change your get url.

Hope that helps you. If it does mark it as an answer.
Thanks.
Hi,
I don't see anything obviously wrong, could you let me know what kind of errors you are getting ? (from the browser console, if you're using chrome dev tools / firebug, etc).
Thank you
