How can I return a JSON result to a Ajax.BeginForm

Question

I have got this simple form:

@using (Ajax.BeginForm(\"CreateProductFromAjaxForm\",\"Product\" , 
                  null, 
                  new AjaxOptions() {           


        

Answer 1

in page

new AjaxOptions() {  
    OnSuccess = "getresult", 
}

in javascript

function getresult(data){
   alert(data.x);
}

in c#

[HttpPost]
public ActionResult CreateProductFromAjaxForm(CreateProductModel model)
{
    if (!ModelState.IsValid)
    {
        return Json("error", JsonRequestBehavior.AllowGet);
    }

   //add to database

    return Json(model, JsonRequestBehavior.AllowGet);
}
