JSON Formatting Error with C# WebMethod

strawlion

Hello, I am getting the following error:

DataTables warning (table id = 'table'); DataTables warning:
JSON data from server could not be parsed. This is caused by a JSON formatting error.

I believe this is because when using a WebMethod in C# the JSON is formatted differently from normal JSON (Everything is wrapped in a d: IE {"d": 42} ).

My code:

JavaScript
[code]
$(document).ready(function () {
$('#table').dataTable({
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "SystemLog.aspx/GetSystemLog"
});
});
[/code]

C#
[code]
[System.Web.Services.WebMethod]
public static string[][] GetSystemLog()
{
return SystemLog.Get2DArray();
}
[/code]


I can successfully store the array of arrays in a javascript variable using a callback function, so I know that the JSON can be parsed and converted correctly outside of the dataTables library. Example:

[code]
var aaData;
function ScriptCallback(result) {
aaData = result;
}
[/code]

The above will correctly store the array of arrays in aaData when calling PageMethods.GetSystemLog(ScriptCallbakc), so I'm not sure why dataTables can't handle this directly?

I am not quite sure how to troubleshoot this error. Can anyone give any insight on this? Thanks!

What does the JSON that is returned look like? Also worth searching the forum as this has come up a number of times before and you'll likely find an asnwer in the other threads.
