Grid won't bind / display data

[Tycho]

Hi all,

I've got a grid that won't bind / display data. 

Datasource:

var ds = new kendo.data.DataSource({

    type: "odata",

    transport: {

        read: {

            url: dataUrl,

            dataType: "jsonp",

            jsonp: "callback",

            jsonpCallback: 'DataCallBack'

        }

    },

    error: function (e) {

            alert("Error2: " + e);

    },

    serverPaging: true,

    pageSize: 10

});

Using firebug i can see a request is being made and the following data in JSONP format is returned by the service: 

DataCallBack( [{"RunStatusTag":null,"Service":"Charge Pump","SiteName":"FCCU"},{"RunStatusTag":null,"Service":"Charge Pump 2","SiteName":"FCCU2"},{"RunStatusTag":null,"Service":"Charge Pump3","SiteName":"FCCU3"}] );

The grid is defined as below, the databound event never fires:

$("#grid2").kendoGrid({

    dataSource:ds,

    dataBound: function(e) {

         alert("Bound2 " + e);

    },

    columns: [

            {   field:"SiteName",title: "Plant/Facility" },

            {   field:"Service",title: "Service"    }

    ]

});

Any idea's?

Tycho,

Have you tried defining a schema for the datasource? In your case, add this to the dataSource object (assuming "SiteName" is a key column):

schema: {

data: "d",

model: {

id: "SiteName",

fields: {

RunStatusTag: { nullable: true },

Service: { type: "string" },
    SiteName: { type: "string" }


}

}

}

What are you using for your service specifically are you using the Web api, Wcf, or some other tehcnology?

@Jerry: i tried adding a schema before, but not exactly like the one you suggested. I tried yours but still the grid doesn't seem to bind. It doesn't give any errors either.

@Jessy : WCF built in ASP.NET 3.5 running on IIS. It's returning the jsonp described above. I've pasted the request and answer headers that i using firebug below.

I think I'm having the same issue, but I'm just calling an MVC Controller method instead of a WCF service.  I've caught the call to the server in debug, so I know it's getting that far.  On my dataSource I've got it doing an alert on requestStart and requestEnd, and both of those are firing, but my grid is never firing its dataBound event either.

Hi Matt,

This thread is old and outdated, it was created in Jun 2012.

Please open a new thread and provide a sample of the server JSON response so we can examine its structure and verify that the DataSource is configured correctly.

Thank you in advance.
