Is there a way using the jsonReader or maybe with an event that a JSON object returned from an AJAX call can be translated into something the jqGrid can understand?

We have standard JSON objects gen'd from data model classes that I can return sort of like this:

{

items: [

{ fname: 'Jon', lname: 'Doe', homeAddress: { address1: '123 Main St.', city: 'Sometown', ... }, status: { id: 1, description: 'active' } },

{ fname: 'Jane', lname: 'Doe', homeAddress: { address1: '123 Main St.', city: 'Sometown', ... }, status: { id: 1, description: 'active' } },

...

]

}

Which is totally non-conformant... is there a way/place I can inject a function in JS to convert it? I tried modifying the "success" function of the xhr via the loadBeforeSend(xhr) event, but it didn't like it.

I'm using 3.8.2 for now, btw.

I actually found a solution for this - adding ajaxGridOptions to my grid config options and using the dataFilter:

ajaxGridOptions: {

dataFilter : function(data, type) {

if (typeof(data) === 'string' && type === 'json') {

data = jQuery.parseJSON(data);

}

return convert(data);

}

the "convert" function takes whatever I received from the AJAX call and converts it to the jqGrid standard with rows / cell / etc. The interesting thing is that regardless of setting the datatype to JSON it seems to always pass in and want returned a string value. So I have to parse the JSON string, convert to a new object, then stringify the converted object before returning it.
