cssasp.netviewcontext

How to use ViewContext?

I have layout page in asp.net MVC application and this page contains a navbar 

 <ul class="sidenavbar">
   <li><a   style="font-size:large">ASP.NET Tutorial</a></li>
   <li>@Html.ActionLink("Home","Home")</li>
   <li>@Html.ActionLink("Introduction", "Introduction")</li>
   <li>@Html.ActionLink("Getting Started", "GettingStarted")</li>
 </ul>

See I have actionmethod for each item in my navbar now I want to apply css class active to currently selected list item how can I achieve this using ViewContext or if there is any better way?

Solution

  • This may work

    <ul class="nav navbar-nav">
  <li class="@(ViewContext.RouteData.Values["controller"].ToString() == "Home" ? "active" : "")">@Html.ActionLink("Home", "Index", "Home")</li>
  <li class="@(ViewContext.RouteData.Values["controller"].ToString() == "About" ? "active" : "")">@Html.ActionLink("About", "About", "Home")</li>
  <li class="@(ViewContext.RouteData.Values["controller"].ToString() == "Contact" ? "active" : "")">@Html.ActionLink("Contact", "Contact", "Home")</li>
</ul>
