ASP.NET AJAX.BeginForm sends multiple requests

ajax.beginformasp.net-mvc-3

Im relatevely new with Asp.net MVC3,

I have a form handled with Ajax, like this:

@using (Ajax.BeginForm("dtjson", new AjaxOptions { HttpMethod = "Post", UpdateTargetId = "detalle_tarifa", OnSuccess = "exito2", OnBegin="bloquear" }))

My problem is that when I submit data, it sends the request twice.

Lets take a look at the view.

This is the form:

ok, now the view after submit:

And this one is to show firebug debugging:

On the layout, I have those javascript files..

   <script src="@Url.Content("~/Scripts/jquery-ui.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.windows-engine.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.jqDock.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.jqDock.min.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.tablePagination.0.4.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.tools.min.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.cookie.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.treeview.js")" type="text/javascript"></script>
       <script src="@Url.Content("~/Scripts/jquery.treeview.edit.js")" type="text/javascript"></script>
        <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>

And on the view (A Partial View), I have this:

<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-ui.js")" type="text/javascript"></script>
<script type="text/javascript" src=@Url.Content("~/Content/tinymce/jscripts/tiny_mce/jquery.tinymce.js")></script>
<script type="text/javascript" src=@Url.Content("~/Content/tinymce/jscripts/tiny_mce/tiny_mce.js")></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
<script src="@Href("~/Scripts/jquery.uploadify.js")" type="text/javascript"></script>
<script src="@Href("~/Scripts/jquery.scrollTo.js")" type="text/javascript"></script>
<script src="@Href("~/Scripts/jquery.blockUI.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="/Scripts/jquery.cookie.js" type="text/javascript"></script>
<script src="/Scripts/jquery.treeview.js" type="text/javascript"></script>
<script src="/Scripts/jquery.treeview.edit.js" type="text/javascript"></script>

It seems like it's a problem with jquery… but Im not sure of it…

Any help would be great, Thanks everybody!

You have included jquery.unobtrusive-ajax.min.js twice once in the layout once in the partial. So your browser executes the js inside twice which will subscribe twice on the form click event that is why doing two POST instead of one.
So you need to remove the jquery.unobtrusive-ajax.min.js from the partial.

Note: If your are using a partial with a layout you don't need to duplicate the js included in the partial because it's already done by the layout. There are some good articles about layouts and partials.
