Fun with callbacks Part 3: Strongly-typed callbacks

Yes, you are correct. It looks a little counter-intuitive at first, but it ensures that the page is in a consistent state during a callback even if multiple callbacks are triggered at once.
The data that you want to be up-to-date must be passed as a part of the callback parameter, and Form will have the values it had during the latest postback.

Bertrand, I meant whether are available the actual input values (at the moment of a callback) which have been changed since the last postback, but from your post I see that they are not available and only old values from the last postback can be obtained (and this is exactly what I observed in my test project). In other words I need to pass manually through the callback args all the information I want to gather from the page. Am I correct?

This is good, but what about the current 1.1 version - this stuff you are doing is all beta material that can't be used on production environments.

See http://www.dart.com/powerweb/livecontrols.asp

I just wish these controls were cheaper :)

Sergey: during a callback, the page is in exactly the same state it was during the last postback, so the Form and QueryString parameters are still available, in addition to the callback parameters. Does that answer your question?

Accessing request params

Callbacks look like great techology capable to improve web controls development significantly.
Thank you Bertrand for introducing the technology and providing us with amazing demos.
My question is: are request params (the form input values) available during callbacks?

Very classy stuff, Bertrand! Especially the RefreshPanel at gotdotnet.
