MVC 3 Ajax.beginform submit - causes full postback

Question

Hi i am trying to get to grips with ajax.beginform using mvc 3.

I have 2 forms, a HTML.BeginForm which works fine and a Ajax.BeginForm in a partial view. The post of the ajax form is to add notes to the model.

The problem is the ajax submit is submitting the whole page including the HTML.BeginForm at in the main view and not performing the asynchronous post with the note.

Can anyone see what im doing wrong?

Ive look at other questions and have disabled the unobtrusive javascript in web.config etc.

View:

<div id="maincontent">
@using (Html.BeginForm())
{
  @Html.ValidationSummary(true)
  <fieldset>
    <legend>Edit Franchise</legend>
    <div class="editor-label">
      @Html.LabelFor(model => model.Name)
    </div>
    <div class="editor-field">
      @Html.EditorFor(model => model.Name)
      @Html.ValidationMessageFor(model => model.Name)
    </div>
    <div class="editor-label">
      @Html.LabelFor(model => model.FirstLine)
    </div>
    <div class="editor-field">
      @Html.EditorFor(model => model.FirstLine)
      @Html.ValidationMessageFor(model => model.FirstLine)
    </div>
    <div class="editor-label">
      @Html.LabelFor(model => model.SecondLine)
    </div>
    <div class="editor-field">
      @Html.EditorFor(model => model.SecondLine)
      @Html.ValidationMessageFor(model => model.SecondLine)
    </div>
    <div class="editor-label">
      @Html.LabelFor(model => model.City)
    </div>
    <div class="editor-field">
      @Html.EditorFor(model => model.City)
      @Html.ValidationMessageFor(model => model.City)
    </div>
    <div class="editor-label">
      @Html.LabelFor(model => model.Postcode)
    </div>
    <div class="editor-field">
      @Html.EditorFor(model => model.Postcode)
      @Html.ValidationMessageFor(model => model.Postcode)
    </div>
    <div class="editor-label">
      @Html.LabelFor(model => model.Telephone)
    </div>
    <div class="editor-field">
      @Html.EditorFor(model => model.Telephone)
      @Html.ValidationMessageFor(model => model.Telephone)
    </div>
    <p class="clear">
      <input type="submit" value="Save" />
    </p>
  </fieldset>

  @Html.Partial("Partial/_AddNote", new Cash4Schools.Domain.Model.Note())

}

Partial View:

@model Cash4Schools.Domain.Model.Note
<script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script>  

@using (Ajax.BeginForm("AddNote", "Franchises", 
  new AjaxOptions {
     HttpMethod = "POST", 
     UpdateTargetId = "note" }, 
     new { id = "ajaxForm" })
     )
{
  @Html.ValidationSummary(true)
   <fieldset>
       <legend>Add a Note</legend>

      <div class="editor-label">
        @Html.LabelFor(model => model.Content)
      </div>
      <div class="editor-field">
        @Html.EditorFor(model => model.Content)
        @Html.ValidationMessageFor(model => model.Content)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.CreationDate)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.CreationDate)
        @Html.ValidationMessageFor(model => model.CreationDate)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.CreatedBy)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.CreatedBy)
        @Html.ValidationMessageFor(model => model.CreatedBy)
    </div>

    <p class="clear">
        <input type="submit" value="Add" />
    </p>
</fieldset>

}

Controller:

[HttpPost]
public ActionResult AddNote(Note model)
{
  var franchise = _franchiseRepository.FindById(model.Id);

  franchise.Notes.Add(
    new Note {
      Content = model.Content,
      CreationDate = DateTime.Now,
      CreatedBy = model.CreatedBy,
      Type = NoteType.Franchise
    }
  );

  _franchiseRepository.Save(franchise);

  return PartialView(franchise.Notes);
}

HTML Output:

<form action="/Franchises/AddNote?Length=10" data-ajax="true" data-ajax-method="POST" data-ajax-mode="replace" data-ajax-update="#note" id="ajaxForm" method="post">    <fieldset>

    </div>
    <div class="editor-field">

        <span class="field-validation-valid" data-valmsg-for="Content" data-valmsg-replace="true"></span>
    </div>
    <div class="editor-label">
        <label for="CreationDate">CreationDate</label>
    </div>
    <div class="editor-field">
        <input class="text-box single-line" data-val="true" data-val-required="The CreationDate field is required." id="CreationDate" name="CreationDate" type="text" value="01/01/0001 00:00:00" />
        <span class="field-validation-valid" data-valmsg-for="CreationDate" data-valmsg-replace="true"></span>
    </div>
    <div class="editor-label">

        <span class="field-validation-valid" data-valmsg-for="CreatedBy" data-valmsg-replace="true"></span>
    </div>

    <p class="clear">
        <input type="submit" value="Add" />
    </p>

</fieldset>
</form><div id="note"></div>

@using (Html.BeginForm())
{
    @Html.ValidationSummary(true)
    <fieldset>

    </fieldset>

    @Html.Partial("Partial/_AddNote", new Cash4Schools.Domain.Model.Note())
    --Partial call and therefore, the form within the partial, is embedded 
    --in the main form
}

change it to

@using (Html.BeginForm())
{
    @Html.ValidationSummary(true)
    <fieldset>
    ....
    </fieldset>

}

@Html.Partial("Partial/_AddNote", new Cash4Schools.Domain.Model.Note())
--Partial call outside main form, no longer embedded. Works

The embedded form within a form is mucking the works up.
