The problem was that the DefaultFocus javascript was not rendered at all.

After investigating the problem, I walked into two problems, solving which solved my problem as well:

1. DefaultButton requires a control’s UniqueID property, but DefaultFocus requires a control’s ClientID property. Strange, but it really works :) !
2. Do not use hyphen characters in your ID properties (I had an auto ID using a GUID), since it will cause your focus to fail (the javascript is not being rendered). If you have or want to use some kind of separation, use the underscore character instead (it will work).

Hope that helps somebody out there too ;) !
