问题 I'm using the Data Annotation validation extensively in ASP.NET MVC 2. This new feature has been a huge time saver, as I'm now able to define both client-side validation and server-side validation in one place.

问题 <% using (Html.BeginForm("SubmitUserName")) { %> <input type='text' name='user-name' /> <input type='submit' value='Send' /> <% } %> What should be a signature of a corresponding Action method to accept user-name parameter? public ActionResult SubmitUserName(string user-name) {...} Method signature above does not work for some reason ;-) I know there is an ActionNameAttribute to handle situation with a dash in action name. Is there something like ParameterNameAttribute ? 回答1: As everyone has

问题 I am making an application that deals with vehicles. I need two DropDownLists: Makes: All Vehicle Makes Models: Models that belong to the selected value of the Make DropDownList How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so

问题 I've given some thought to implementing badges (just like the badges here on Stack Overflow) and think it would be difficult without Windows services, but I'd like to avoid that if possible. I came up with a plan to implement some examples: Audobiographer: Check if all fields in the profile is filled out.
