问题 I'd like to wrap a span with an action link because I'm adhering to an existing CSS theme. It doesn't look like any of Html.ActionLink 's constructors allow for this.

问题 So I'm looking into writing some custom MVC extensions and the first one I'm attempting to tackle is a FormattedTextBox to handle things such as currency, dates, and times. I have the rendering of it working perfectly, formatting it, working with strong types and everything all golden.
