You can put a flag in your navbar in _Layout.cshtml page.

1. Get data from the database to know if your use is registered or not? If yes then set the flag to TRUE in your ViewBag.

Code in your controller:

ViewBag.IsRegistered= true;

2. And pass this model in your cshtml page

Here is the sample:

    <div class="navbar-collapse collapse">  
        <ul class="nav navbar-nav">  
            <li>  
                <a href="@Url.Action("Index", "Home")">  
                    <span class="glyphicon glyphicon-home"></span>  
                      Home  
                </a>  
            </li>  
            <li>  
                <a href="@Url.Action("Register", "Register")">  
                    <span class="glyphicon glyphicon-search"></span>  
                    Register
                </a>  
            </li>  
            <li>  
            <a href="@Url.Action("Login", "Login")">  
                Login
            </a>  
            </li> 
            @{ 
            if(@ViewBag.IsRegistered){
            <li>  
            <a href="@Url.Action("Search", "Home")">  
                <img src="path to image" alt="test"> 
            </a>  
            </li> 
              }    
            }
        </ul>  
    </div>
