C# Adding callback to JsonResult

Question

My mvc page returns json by using the function Json(mycustomclass) to return a JsonResult object.

This works just fine except, I need to wrap the json in a callback so that jQuery can use it.

I want it like this:
jsonp1246168411282({"myjson":"some values"})

but I am getting this: {"myjson":"some values"}

Is there any way I can 'wrap' the C# JsonResult with brackets and the jquery callback?

Thanks

For anyone else that needs a solution to this and doesn't want to use a WCF Service check this link out : http://stimms.blogspot.com/2009/04/aspnet-mvc-returning-jsonp.html — Simeon Wislang, Jun 28 '09 at 09:59
or alternatively you can do this: string json_string = (callback + "(" + new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(json) + ")"); JavaScriptResult result = new JavaScriptResult(); result.Script = json_string; return result; — Simeon Wislang, Jun 28 '09 at 10:20

Jquery can use the json response just fine unless you are calling this action from a page in another domain. Is this what you are doing? If so I advise you to create a wcf service which supports jsonp. Example here

If not you can just use the getJson jquery method.

Hi redsquare. Yes, my service needs to be accessible from other domains. Currently I have I view page that returns the json but I am working on a better solution that allows me to serialize a large custom class into json and return it as an object. I might just use an open source json serializer to turn it into a string and return it as a string. Thanks for your help thought. Best Regards, The Lorax – Simeon Wislang Jun 28 '09 at 09:28

ASP.net MVC returning JSONP

Also, something like:

public JavaScriptResult Test()
{
    JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer();
    string callback = Request.Params["callback"] + "(" + javaScriptSerializer.Serialize("testing, testing") + ");";
    return JavaScript(callback);
}
