I have a Tabcontrol inside a ModalPopupextender that is displayed only on a button click. when the page does a postback I get this stupid error:
htmlfile: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.
The Tab Control should check if it is visible prior to setting the focus on the first tab. Should be an easy fix.
Please fix this ASAP.
Thanks.
Alex
