Thanks Marcelo,
Would you provide me a simplified page and usercontrol with some buildin
controls(button or textboxes) that are dynamicall loaded and bind event
handlers so that I can perform some test on them?

| Steven,
|
| Yes, you got it right. the events are builtin events, when I need to
| bubble-up events to the parent usercontrol (for example to remove the
child
| control) that works fine, simple built-in events like button onclick are
the
| events that need to be triggered twice before getting processed.
|
| Thanks,
| Marcelo Cabrera.
