MVC area

You have to add area to every action link otherwise link will be messed up.

@using Microsoft.AspNet.Identity
@if (Request.IsAuthenticated)
{
    using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new {area = "", id = "logoutForm", @class = "navbar-right" }))
    {
    @Html.AntiForgeryToken()

    <ul class="nav navbar-nav navbar-right">
        <li>
            @Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { area = "",title = "Manage" })
        </li>
        <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li>
    </ul>
    }
}
else
{
    <ul class="nav navbar-nav navbar-right">
        <li>@Html.ActionLink("Register", "Register", "Account", routeValues: null, htmlAttributes: new {area = "", id = "registerLink" })</li>
        <li>@Html.ActionLink("Log in", "Login", "Account", routeValues: null, htmlAttributes: new { area = "", id = "loginLink" })</li>
    </ul>
}

Linking Between Two Areas

ASP.NET MVC Views often need to link to some action method residing in controller classes. Unless otherwise specified, action methods and controllers are assumed to be from the current area. In case you wish to link to an action method belonging to some other area, here is how you would do just that:

<h3>You are inside main area. To navigate to some other area please click on the following links</h3>
<%= Html.ActionLink("Main Area", "Index", "Home", new { area = "" }, null)%>
<br /><br />
<%= Html.ActionLink("Blog Area", "Index", "Home", new { area = "Blog" }, null)%>
<br /><br />
<%= Html.ActionLink("Help Desk Area", "Index", "Home", new { area = "HelpDesk" }, null)%>
<br /><br />
<%= Html.ActionLink("Shopping Area", "Index", "Home", new { area = "Shopping" }, null)%>

The above fragment is from the Index view of the main area. It renders four hyperlinks using ActionLink(). Notice the fourth parameter that specifies area name. This parameter governs the area whose action method is being linked to.

Redirecting to an Action Belonging to Another Area

You can also redirect to some action method of a specific area using RedirectToAction() method. Consider the following action method:

public ActionResult Index()
{
    return RedirectToAction("Index", "Home", new { Area = "HelpDesk" });
}

As you can see, the Index() action method of the main area redirects the control to Index() action method of the HelpDesk area.

Property	Description
Url	The Url property indicates a URL to which the form is to be submitted. You can also specify a controller and action method in the BeginForm() method instead of setting the URL property.
HttpMethod	The HttpMethod property indicates the HTTP method (GET or POST) to be used while making an Ajax request.
Confirm	The Confirm property is used to specify a message that will be displayed in a confirm dialog to the end user. If user clicks OK on the confirmation dialog the Ajax call is made.
OnBegin	The OnBegin property specifies a name of JavaScript function that is called at the beginning of the Ajax request.
OnComplete	The OnComplete property specifies a name of JavaScript function that is called at the end of the Ajax request.
OnSuccess	The OnSuccess property specifies a name of JavaScript function that is called when the Ajax request is successful.
OnFailure	The OnFailure property specifies a name of JavaScript function that is called if the Ajax request fails.
LoadingElementId	While an Ajax request is being made you can display a progress message or animation to the end user. The LoadingElementId indicates an ID of a DOM element that is serving this purpose. Note that the Ajax helper will simply display and hide this element. Displaying some progress message of animation inside this element is your responsibility.
LoadingElementDuration	The LoadingElementDuration property specifies a time duration in milliseconds that controls the duration of the progress message or animation.
UpdateTargetId	The UpdateTargetId property specifies an ID of a DOM element that will be populated with the HTML returned by the action method.
InsertionMode	The InsertionMode property governs how the HTML replacement should occur in a DOM element as specified by UpdateTargetId property. The possible values are InsertAfter, InsertBefore and Replace.
