asp.net - How to Use Ajax.BeginForm OnSuccess and OnFailure Methods?

Question

I using this Ajax.BeginForm

    <% using( Ajax.BeginForm( "Create","Mandate",
                       new AjaxOptions( ) {
                           OnSuccess = "GoToMandates",
                           OnFailure = "ShowPopUpError"
                       } ) ) {%>

<% } %>

What do I need to write in the controler to catch this OnSucces and OnFailure.

Because OnSuccess I need to show Success message

OnFailure I need to show othere message.

In my Controller

Public ActionResult GetSomething(FromCollection collection)
{
     if(exists == null)
     {
          //OnSuccess
     }
     else
     { 
         //OnFailure
     }
}

Can anydboy help me out.. how to catch this?

Thanks

The OnSuccess and OnFailure looks like they are expecting javascript callback functions.

<script type="text/javascript">
    function handleError(ajaxContext) {
    var response = ajaxContext.get_response();
    var statusCode = response.get_statusCode();
    alert("Sorry, the request failed with status code " + statusCode);
    }
</script>

<%= Ajax.ActionLink("Click me", "MyAction",
new AjaxOptions { UpdateTargetId = "myElement", OnFailure = "handleError"}) %>

Added Controller Example

The simpliest way to do this would be what I've got here but I recommend looking into strongly typed mvc views using some kind of ViewModel and maybe look into using jQuery for your ajax. With that said this should hopefully work for you.

if (exists)
{
  ViewData["msg"] = "Some Success Message";
}
else
{
  ViewData["msg"] = "Some Error Message";
}

return View();

In your view

<div id="myResults" style="border: 2px dotted red; padding: .5em;">
    <%: ViewData["msg"]%>
</div>
