I have the following situation: A user will define a certain filter on a page, and on postback I will query the database using that filter and return a bunch of matching records to the user, each with a checkbox next to it, so he can choose whether to act on each of those records. In Classic ASP / PHP I can generate a lot of controls n...

Unfortunately, when ViewState is disab...
