Clean way to pass data to Master Page from View in ASP.NET MVC2 (set css class from view) - asp.net-mvc-2

Question

I have a ASP.NET MVC2 application with a master page. The master page renders the site layout divs as follows:
<div id="wrapper">
<div id="column1">
{contentplaceholder}
</div>
<div id="column2">
{contentplaceholder}
</div>
</div>
In my View, I would like to apply a classname to the wrapper div, so when viewing the homepage, the wrapper div would be:
<div id="wrapper" class="homepage">
</div>
or on the contact page it would be
<div id="wrapper" class="contact">
</div>
Ideally I would like to set this variable in the view aspx page, rather than in a controller action. What would be the cleanest way to achieve this? I was thinking something along the lines of:
In Master page:
<div id="wrapper" class="<%=WRAPPER_CLASS%>">
</div>
and then in View:
<% WRAPPER_CLASS = "contact"; %>
(obviously the above example doesn't work, but does anyone have any good ideas?)

Answer 1

Why not try this, within the master page:
<div id="wrapper" class="<asp:ContentPlaceHolder ID="page-class" runat="server" />">
</div>
and in the aspx view
<asp:Content ID="page-class-content" ContentPlaceHolderID="page-class" runat="server">
homepage
</asp:Content>
