Some people get nervous when they read that Ivonna doesn't support AJAX. I decided to clarify this issue.

The current version of Ivonna supports Ajax-enabled controld. It means that if you add an UpdatePanel, or even a TabContainer, to your page, nothing bad happens. There are some known problems, namely, if you place a password control inside a tab, its value won't get read on a postback. So, let's say that a TabContainer is almost supported.

Ivonna doesn't support callbacks. Everithing works like Ajax is not enabled. For example, if you have an UpdatePanel, and you disable partial endering, a callback will become a regular postback, and this is how Ivonna will treat the situation, regardless of the partial rendering enabled or not. In other words, you'll have the same results, except that the IsCallback property will be set to false.

If you want to develop some more sophisticated AJAX stuff and test it with Ivonna, I'll be happy to listen to your suggestions. Keep in mind, however, that most of it would be client-side scripts that are not in the Ivonna's domain.
