Brock,
Thank you for your explanation. However, I encounter an error when cached
page is used to execute my request instead of new page, when I do the
following:
1) Click "Back" button on my internet explorer, which brings my cached page.
2) Then click on *any* control that has a handler.
"An error has occurred because a control with auto-generated id '_ctl6'
could not be located to raise a postback event. To avoid this error,
explicitly set the ID property of controls that raise postback events. "
Do you know why that happens?
Thanks,
Amelyan
