c# razor url parameter from view

Why does Request["parameterName"] returns null within the view? I know I can get it from the controller but I have to make a little check in the View. I am using ASP.NET MVC 3.

@(ViewContext.RouteData.Values["parameterName"])

worked with ROUTE PARAM.

Request.Params["paramName"]

did not work with ROUTE PARAM.

You can use the following:

Request.Params["paramName"]

If you're doing the check inside the View, put the value in the ViewBag.

In your controller:

ViewBag["parameterName"] = Request["parameterName"];

It's worth noting that the Request and Response properties are exposed by the Controller class. They have the same semantics as HttpRequest and HttpResponse.
