HTML.Button in ASP.NET MVC

I figured it out. It goes something like this:

<form method="post" action="<%= Html.AttributeEncode(Url.Action("CastUpVote")) %>">
<input type="submit" value="<%=ViewData.Model.UpVotes%> up votes" />
</form>

Several of the extension methods got moved to Microsoft.Web.Mvc, which is the MVC Futures DLL. You might want to look there for things that have gone missing.

Just write <input type="button" ... /> into your html. There's nothing special at all with the html controls.
