David,

How do I use this with query string (i.e. Default.aspx?Action=1)

Hien Khieu: the constants are a replacement to hard coded literal strings, and can be used the same way. So you can certainly append extra things to them. But note that the value of the constant in the ~/ virtual path, which is not meant for client consumption. It's only meant for server side usages like LoadControl.

Thank you very much, David.

Your T4 stuff is awesome.

Haha, I did something like this a while ago.

But I don't really maintain it anymore. Nice work :)

For those interested in factoring out the paths, I've always taken the following approach (Only works in Web Projects, not Web Applications). Create multiple, static "URL" methods on each page's code-behind. Each method should be a valid "signature" for the page, with strongly-typed arguments. The method should return the proper URL for calling that page with the provided arguments. This puts the "magic path string" as well as the URL concatenation logic into the page itself. Now none of the rest of the application needs to know where the page is, or what its parameters are called.

Is there a way to create a richer code generation by building a custom T4 host for ASP.NET forms web application?

How hard would be to add menu items to WAP project to build MVP kind of classes (view and presenters) from Model classes? I guess we could right click on a model class (business entity and you would be presented with 2 menu items to generate Presenter and View)?

Thanks,

Rad

Rad: this could certainly be done, but it would be completely different from this template, because it would do 'one time generation' instead of 'support code' (see this post: http://blogs.msdn.com/davidebb/archive/2009/07/17/two-ways-to-use-t4-templates-support-code-vs-one-time-generation.aspx). What you're describing would be analogous to what ASP.NET MVC supports (e.g. Add View).
