Question

Here are the codes

public class MyModel
{
   [Required]
   public string Title {get;set;}

}


public class MyController : Controller
{
     public ActionResult Post(MyModel model)
     {
          if (!ModelState.IsValid)
             return PartialView(model);

          return PartialView("SomeOtherView"); 
     }



}

Here is my View

   @model MyModel

   @using(Ajax.BeginForm("Post","My",new AjaxOptions{OnSuccess = "Sucess" }) {
         Html.Partial("Post",Model)

  }

<script>
 function Success(content)
 {
   $("#somediv").html(content);

 }


</script>

Now, when ModelState Dictionary has no error, everything goes well, but when there is some model validation error, I have no way to detect it in javascript. Can someone help here.

There are different ways to achieve this. One way is to have the server side send a proper HTTP code (500) in case of error:

if (!ModelState.IsValid)
{
    Response.StatusCode = 500;
    return PartialView(model);
}

and on the client subscribe for the OnFailure callback and handle the error case in a different function.
