问题 I need to write a little wizard application into which a user inputs some information. I was going to write this as a silverlight application.

问题 Okay, my site is www.kristianbak.com. I have a css class called activebutton . I want that to change whenever another View is active. Currently it's merely hard-coded in the HTML (sitemaster).

So I need a radio button which records to the database it's value like normal which I have setup with a RadioButtonFor and if "No"(false) is selected then a group/list of other radiobuttons will display.

问题 We have an MVC.Net 2 application running with .Net 4.0. There are cases where embedded code in our views may err, sending malformed HTML to the browser. How can I tell Internet Explorer to close any open attributes and elements so it can properly render an error message? To catch and log errors in the embedded code, I'm enclosing the view's HTML and embedded code in the try block of a try-catch structure and just want a simple message displayed to the user after logging the error. Example: <%

问题 I am making an ajax call to my controller which is going to perform a long operation. The operation can fail for many reasons or succeed. If I want to force the failure code of my ajax call to execute ("error"), what do I need to do in my controller before returning?
