I am having some issues with getting data to display using the igGrid.  I am programming in asp.net and calling a webmethod that returns json object back to the javascript.

Here is my code.

function test_json() {
    simpleLoad('orderdetail.aspx/GetOrderTotal', { orderid: '40069' }, testjson_success);
    return false;
}

my webmethod

Public Shared Function GetOrderDetail(ByVal PostData)
        Dim outputObj As New Dictionary(Of String, String)

        Dim _orderLines As EmunWorks.Info.SalesOrderLinesTotalInfo()
        Dim _orderLinesDB As New EmunWorks.DataAccess.SalesOrderLinesDB
        _orderLines = _orderLinesDB.GetSalesOrderLineTotals("40069")

        Dim jsSerializer As System.Web.Script.Serialization.JavaScriptSerializer
        jsSerializer = New System.Web.Script.Serialization.JavaScriptSerializer()

        Dim sbOrder As New System.Text.StringBuilder()

        jsSerializer.Serialize(_orderLines(0), sbOrder)

        Dim json As String = sbOrder.ToString()
        Return json
    End Function

if data get is successful then this
function testjson_success(data) {

    $("#grid1").igGrid({
        autoGenerateColumns: false,
         columns: [
            { headerText: "Line Count", key: "lineCount", dataType: "number" },
            { headerText: "Qty Count", key: "qtyCount", dataType: "numbers" }
        ],
        dataSource: data,
        width: '500px'
    });

}

the data object returns this json response.

{"d":{"lineCount":"23","qtyCount":"56","extendedSum":"$5,000.16"}}

I have also tried this response, but no luck

"{"LineCount":23,"QtyCount":56,"ExtendedSum":5000.1600000000008}"

my web method is really a an object that i Serialize to json

object.LineCount

object.QtyCount

Any help would be greatly appreciated.
