Just found out that ASP.NET 2.0 doesn’t support dynamically loading “bindable” templates from a file; you’re restricted to writing them inline. In other words, if you’re using a FormView or DetailView control, and plan to use the new two-way data binding features, any use of LoadTemplate is out of the window. Plus the BindableTemplateBuilder (for creating a two-way data bound template on the fly) is currently an internal class. Which seems a big shame… (or maybe it’s just me??)

Does anyone know of any potential ways around this?

(Since finding this out, I’ve put in a request to at least make BindableTemplateBuilder a public class here).
