Answer 1

It depends in which part of the Web Page life cycle you are creating the controls.

If you want the controls to handle postbacks and events, you must create them in the pages "OnInit" or "OnPreInit" function.

If you are creating these controls on Page_Load or later, it's too late. The controls will not fire events or hold user changes, because by then the postback information has already been processed.

Answer 2

Try setting the checkbox's AutoPostBack property to true. If that doesn't fix the problem, then it's likely a lifecycle issue, as Andrew said.
