Question

I made a form with @using(Ajax.BeginForm){}. It posts to a method in my controller that returns a PartialViewResult. It works fine when everything is valid, but what should I return if
it’s not (e.g., the modelstate is not valid)?
How Ajax.BeginForm can manage the error? What I return to manage the Failure?

@using(Ajax.BeginForm("Create", "Room", new AjaxOptions { HttpMethod="POST",
UpdateTargetId="formRoom", InsertionMode= InsertionMode.Replace, onFailure =??})) {

public PartialViewResult Create(Movie mov)
{
        if (ModelState.IsValid)
        {
            db.Save(mov);
            return PartialView("CreateResult", mov);
        }
        return null;            
}

Thanks!

You may return another View.

e.g. return PartialView("MyErrorView");
