问题 While creating a simple custom expander, I encountered the problem where items inside IT wouldn't bind. I found the fix on this link: http://codeoverload.wordpress.com/2012/03/04/wpf-expander-headertemplates-dont-forget-the-binding/ Which happens to treat that exact same issue, however what I understand from it is "found this by luck, not really sure why it worked ;D" My question being now: why does adding Header={Binding} fixes the issue.

问题 Here's a simplification of my real models in ASP.NET MVC, that I think will help focus in on the problem: Let's say I have these two domain objects: public class ObjectA { public ObjectB ObjectB; } public class ObjectB { } I also have a view that will allow me to create a new ObjectA and that includes selecting one ObjectB from a list of possible ObjectBs.
