I have got this simple form:
@using (Ajax.BeginForm(\"CreateProductFromAjaxForm\",\"Product\" , null, new AjaxOptions() {
Try specifying the HTTP method:
new AjaxOptions() { OnSuccess = "getresult", HttpMethod = "post" }
Example:
@using (Ajax.BeginForm("CreateProductFromAjaxForm", "Product" , null, new AjaxOptions() { OnSuccess = "getresult", HttpMethod = "post" }, null)) { .... }
