ModalPopupExtender OK Button click event not firing?

Question

I have a Button inside an UpdatePanel. The button is being used as the OK button for a ModalPopupExtender. For some reason, the button click event is not firing. Any idea

Answer 1

It appears that a button that is used as the OK or CANCEL button for a ModalPopupExtender cannot have a click event. I tested this out by removing the

OkControlID="ModalOKButton"

from the ModalPopupExtender tag, and the button click fires. I'll need to figure out another way to send the data to the server.
